As previously touched on in C2H4’s FW20 collection, the Quark and Atom are built on top of Vibram models meaning they are chunky, functional, and hard-wearing. The Quark is a low-top sneaker that’s. A quark (/ k w ɔːr k, k w ɑːr k /) is a type of elementary particle and a fundamental constituent of matter. Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons, the components of atomic nuclei. All commonly observable matter is composed of up quarks, down quarks and electrons. Intel Quark is a line of bit x86 SoCs and microcontrollers by Intel, designed for small size and low power consumption, and targeted at new markets including wearable devices. The line was introduced at Intel Developer Forum in Quark processors, while slower than Atom processors, are much smaller. Only two types of quark are necessary to build protons and neutrons, the constituents of atomic nuclei. These are the up quark, with a charge of + 2/ 3e, and the down quark, which has a charge of − 1/ 3e. The proton consists of two up quarks and one down quark, which gives it a total charge of + e.

Spin is an intrinsic property of elementary particles, and its direction is an important degree of freedom. It is sometimes visualized as the rotation of an object around its own axis hence the name " spin " , though this notion is somewhat misguided at subatomic scales because elementary particles are believed to be point-like.

A quark of one flavor can transform into a quark of another flavor only through the weak interaction, one of the four fundamental interactions in particle physics.

By absorbing or emitting a W boson , any up-type quark up, charm, and top quarks can change into any down-type quark down, strange, and bottom quarks and vice versa.

Both beta decay and the inverse process of inverse beta decay are routinely used in medical applications such as positron emission tomography PET and in experiments involving neutrino detection.

While the process of flavor transformation is the same for all quarks, each quark has a preference to transform into the quark of its own generation.

The relative tendencies of all flavor transformations are described by a mathematical table , called the Cabibbo—Kobayashi—Maskawa matrix CKM matrix.

Enforcing unitarity , the approximate magnitudes of the entries of the CKM matrix are: [68]. There exists an equivalent weak interaction matrix for leptons right side of the W boson on the above beta decay diagram , called the Pontecorvo—Maki—Nakagawa—Sakata matrix PMNS matrix.

According to quantum chromodynamics QCD , quarks possess a property called color charge. There are three types of color charge, arbitrarily labeled blue , green , and red.

Every quark carries a color, while every antiquark carries an anticolor. The system of attraction and repulsion between quarks charged with different combinations of the three colors is called strong interaction , which is mediated by force carrying particles known as gluons ; this is discussed at length below.

The theory that describes strong interactions is called quantum chromodynamics QCD. A quark, which will have a single color value, can form a bound system with an antiquark carrying the corresponding anticolor.

This is analogous to the additive color model in basic optics. Similarly, the combination of three quarks, each with different color charges, or three antiquarks, each with anticolor charges, will result in the same "white" color charge and the formation of a baryon or antibaryon.

In modern particle physics, gauge symmetries — a kind of symmetry group — relate interactions between particles see gauge theories.

Color SU 3 commonly abbreviated to SU 3 c is the gauge symmetry that relates the color charge in quarks and is the defining symmetry for quantum chromodynamics.

SU 3 c color transformations correspond to "rotations" in color space which, mathematically speaking, is a complex space.

Every quark flavor f , each with subtypes f B , f G , f R corresponding to the quark colors, [74] forms a triplet: a three-component quantum field that transforms under the fundamental representation of SU 3 c.

In particular, it implies the existence of eight gluon types to act as its force carriers. Two terms are used in referring to a quark's mass: current quark mass refers to the mass of a quark by itself, while constituent quark mass refers to the current quark mass plus the mass of the gluon particle field surrounding the quark.

Most of a hadron's mass comes from the gluons that bind the constituent quarks together, rather than from the quarks themselves.

While gluons are inherently massless, they possess energy — more specifically, quantum chromodynamics binding energy QCBE — and it is this that contributes so greatly to the overall mass of the hadron see mass in special relativity.

The Standard Model posits that elementary particles derive their masses from the Higgs mechanism , which is associated to the Higgs boson.

In QCD, quarks are considered to be point-like entities, with zero size. The following table summarizes the key properties of the six quarks.

Mass and total angular momentum J ; equal to spin for point particles do not change sign for the antiquarks. As described by quantum chromodynamics , the strong interaction between quarks is mediated by gluons, massless vector gauge bosons.

Each gluon carries one color charge and one anticolor charge. In the standard framework of particle interactions part of a more general formulation known as perturbation theory , gluons are constantly exchanged between quarks through a virtual emission and absorption process.

When a gluon is transferred between quarks, a color change occurs in both; for example, if a red quark emits a red—antigreen gluon, it becomes green, and if a green quark absorbs a red—antigreen gluon, it becomes red.

Therefore, while each quark's color constantly changes, their strong interaction is preserved. Since gluons carry color charge, they themselves are able to emit and absorb other gluons.

This causes asymptotic freedom : as quarks come closer to each other, the chromodynamic binding force between them weakens.

The color field becomes stressed, much as an elastic band is stressed when stretched, and more gluons of appropriate color are spontaneously created to strengthen the field.

Above a certain energy threshold, pairs of quarks and antiquarks are created. These pairs bind with the quarks being separated, causing new hadrons to form.

This phenomenon is known as color confinement : quarks never appear in isolation. The only exception is the top quark, which may decay before it hadronizes.

Hadrons contain, along with the valence quarks q v that contribute to their quantum numbers , virtual quark—antiquark q q pairs known as sea quarks q s.

Sea quarks form when a gluon of the hadron's color field splits; this process also works in reverse in that the annihilation of two sea quarks produces a gluon.

The result is a constant flux of gluon splits and creations colloquially known as "the sea". Despite this, sea quarks can hadronize into baryonic or mesonic particles under certain circumstances.

Under sufficiently extreme conditions, quarks may become "deconfined" out of bound states and propagate as thermalized "free" excitations in the larger medium.

In the course of asymptotic freedom , the strong interaction becomes weaker at increasing temperatures.

Eventually, color confinement would be effectively lost in an extremely hot plasma of freely moving quarks and gluons.

This theoretical phase of matter is called quark—gluon plasma. The exact conditions needed to give rise to this state are unknown and have been the subject of a great deal of speculation and experimentation.

An estimate puts the needed temperature at 1. The quark—gluon plasma would be characterized by a great increase in the number of heavier quark pairs in relation to the number of up and down quark pairs.

Given sufficiently high baryon densities and relatively low temperatures — possibly comparable to those found in neutron stars — quark matter is expected to degenerate into a Fermi liquid of weakly interacting quarks.

This liquid would be characterized by a condensation of colored quark Cooper pairs , thereby breaking the local SU 3 c symmetry.

Because quark Cooper pairs harbor color charge, such a phase of quark matter would be color superconductive ; that is, color charge would be able to pass through it with no resistance.

Elementary particle. A proton is composed of two up quarks , one down quark , and the gluons that mediate the forces "binding" them together.

The color assignment of individual quarks is arbitrary, but all three colors must be present. Murray Gell-Mann George Zweig Quarks are observed to occur only in combinations of two quarks mesons , three quarks baryons.

There was a recent claim of observation of particles with five quarks pentaquark , but further experimentation has not borne it out.

The masses must be implied indirectly from scattering experiments. The numbers in the table are very different from numbers previously quoted and are based on the July summary in Journal of Physics G, Review of Particle Physics, Particle Data Group.

A summary can be found on the LBL site. The masses quoted are model dependent, and the mass of the bottom quark is quoted for two different models.

But in other combinations they contribute different masses. In the pion , an up and an anti-down quark yield a particle of only The masses of C and S are from Serway, and the T and B masses are from descriptions of the experiments in which they were discovered.

Each of the six "flavors" of quarks can have three different " colors ". The quark forces are attractive only in "colorless" combinations of three quarks baryons , quark-antiquark pairs mesons and possibly larger combinations such as the pentaquark that could also meet the colorless condition.

Quarks undergo transformations by the exchange of W bosons, and those transformations determine the rate and nature of the decay of hadrons by the weak interaction.
