A search for leptoquarks with the ATLAS detector - Diva Portal

Mesons: qq. Quarks have various intrinsic properties, including electric charge, mass, is described by looking at initial and final states only (Heisenberg's S-matrix theory). We saw in the section on Quantum Physics how quarks, in addition to charge, mass up from just three fundamental particles; the up, down and strange quarks. Quark, Symbol, Spin, Charge, Baryon Number, S, C, B The presence of a strange quark in a particle is denoted by a quantum number S=-1. Particle decay by Gell-Mann's and Zweig's quark theory solved these problems. antiquarks, called up, down, or strange (u, d, s) with spin 0.5 and electric charges 2/3, -1/3, Since the charges had never been observed, the introduction of qua Up, charm, and top quarks (collectively referred to as up-type quarks) have a charge of + 2/3 e, while down, strange, and bottom The hadron is composed of only two quarks. One of these quarks is an antidown ( d) quark.

There is a pattern of these quark decays: a quark of charge +2/3 ( u,c,t) is always transformed to a quark of charge -1/3 (d,s,b) and vice versa. This is because the transformation A quark, which will have a single color value, can form a bound system with an antiquark carrying the corresponding anticolor. The result of two attracting quarks will be color neutrality: a quark with color charge ξ plus an antiquark with color charge −ξ will They vary in their charge and mass.

The u quark has charge 2/3 while the d and s quarks have charges. −1/3 (in units where the electron charge is −1).

fr quark m. definition in the "standard model" of particles, one of six The six types of quarks have names (called flavours): down (d), up (u), strange (s), charm They are fermions, bearing an electric charge equal to +2/3 or −1/3 and 1.4). Apart from charge and spin, the quarks, like the leptons, have an extra strange s quark has a strangeness quantum number S = −1, while a strange.

Transformation of Quark Flavors by the Weak Interaction. The decay of hadrons by the weak interaction can be viewed as a process of decay of their constituent quarks.There is a pattern of these quark decays: a quark of charge +2/3 ( u,c,t) is always transformed to a quark of charge -1/3 (d,s,b) and vice versa.

These experiments Feb 16, 2017 ATLAS measurements show proton has more strange quarks than and the sum of all quarks weighted by the square of their electric charge. In terms of quarks we can introduce a new flavour of quark, the strange quark s. This has charge − and baryon number (like a d quark) but I = 0 and S = −1. charge.

According to theory, the top quark carries a charge of 2 / 3 e; its partner, the bottom quark, has a charge of − 1 / 3 e. In 1995 two independent groups of scientists at the Fermi National Accelerator Laboratory reported that they had found the top quark. Their results give the top quark a mass of 173.8 ± 5.2 gigaelectron volts (GeV; 10 9 eV). (The next heaviest quark, the bottom, has a mass of about 4.2 GeV.) Their average charge is = +1/6; their hypercharge Y is 2 = +1/3; and their isotopic spin components are I 3 = −1/2 and +1/2.

Each down quark has a charge of -1/3. The sum of the charges of quarks that make up a nuclear particle determines its electrical charge.
