Figure 6.6. The transverse decay length (Lxy) of the tracks coming from the secondary vertex. If a secondary vertex is reconstructed on the opposite side of the primary vertex from the jet direction Lxy < 0 and the jet is much more likely to have come from a light quark than a b quark. - "A measurement of the top quark's charge"
av M Mårtensson · 2019 — leptoquarks where both leptoquarks decay to a b-quark and a t -lepton. quarks (down, strange, and bottom) have an electric charge of -1/3 e.
Search for a vectorlike quark with charge 2/3 in t+Z events from pp Together with the up quark, it forms the neutrons (one up quark, two down quarks) and protons (two up quarks, one down quark) of atomic nuclei. It is part of the first generation of matter, has an electric charge of − 1 / 3 e and a bare mass of 4.7 +0.5 −0.3 MeV/c 2. quote the 1S mass.

The six quarks, in order of increasing heaviness, are listed below.
From: Encyclopedia of Physical Science … Other articles where Strange quark is discussed: quark: Quark flavours: Strange quarks (charge −13e) occur as components of K mesons and various other extremely short-lived subatomic particles that were first observed in cosmic rays but that play no part in ordinary matter. The history of the proposal of the quark model of hadrons is interesting.. The quark model was independently proposed by physicists Murray Gell-Mann and George Zweig in 1964. The proposal came shortly after Gell-Mann's 1961 formulation of a particle classification system known as the [Eightfold Way]—or, in more technical terms, SU(3) flavor symmetry.
Antiquarks have the same mass as the corresponding quark, but an opposite electric charge (–2/3 or +1/3) and an opposite color charge… Search for a vectorlike quark with charge 2/3 in t+Z Let's focus on the following item: In quantum electrodynamics (QED) (+2/3) electric charge and a down quark (d) with (-1/3) electric charge P(udu) while neutrons comprise up-down-down, N(udd).
(physics) In the Standard Model of particle physics, a property possessed by quarks, anti-quarks, and gluons that determine rules for how these particles may
Antiparticles • For every quark, there exists a corresponding antiquark. • Antiquarks have the same mass as the corresponding quark, but an opposite electric charge (–2/3 or +1/3) and an opposite color charge… In which Hank plays a song for youthe video was made in Illustrator and After Effects and it took a ridiculously long time to do.
particles with unbelievably strange names: bosons and leptons, quarks and in theory), depending on its charge, it would behave differently.
The up quark (charge 2 / 3 e) and down quark (charge − 1 / 3 e) make up protons and neutrons and are thus the ones observed in ordinary matter. Strange quarks (charge − 1 / 3 e) occur as components of K mesons and various other extremely short-lived subatomic particles that were first observed in cosmic rays but that play no part in ordinary matter. SparkCharge is a company dedicated to making EV ownership easy by creating Charging as a Service, a convenient way for drivers to have their electric vehicles charged. They have created the world's first and only portable, ultra-fast EV charging system called the Roadie. They have also created BoostEV. Strange quark is denoted by S, and its antiparticle is denoted by S. Its electric charge is -1/3 e. Only two types of quark are necessary to build protons and neutrons, the constituents of atomic nuclei.
This has charge − and baryon number (like a d quark) but I = 0 and S = −1. charge. 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).

Let's focus on the following item: In quantum electrodynamics (QED) (+2/3) electric charge and a down quark (d) with (-1/3) electric charge P(udu) while neutrons comprise up-down-down, N(udd).
What does strange quark mean? Information and translations of strange quark in the most comprehensive dictionary definitions resource on the web. The gluons have no charge, and the charges of quarks and antiquarks cancel, but the extra up quarks each have 2/3 of the charge of the proton (4/3 altogether), while the extra down quark adds charge of -1/3 of the proton’s charge. Thus 2/3 + 2/3 – 1/3 = 1 gives the proton’s charge. Occam’s razor and recent data from CERN on photon-photon interactions favour a highly P.C.M.
