First, quarks had to have half-integer spin (intrinsic angular momentum) values for the model to work, but at the same time they seemed to violate the Pauli exclusion principle, which governs the behaviour of all particles (called fermions) having odd half-integer spin.

Using a quark combination model with the equal-velocity combination approximation, we study the production of hadrons with strangeness and charm flavor quantum numbers in Pb+Pb collisions at sNN= 5.02 TeV. We present analytical expressions and numerical results for these hadrons’ transverse momentum spectra and yield ratios. Our numerical results agree well with the experimental data ...Pentaquarks are heavier cousins of protons and neutrons, which are also made of quarks. In ordinary matter, quarks come in two types, up and down. Atom smashers can blast four heavier types of quarks into brief existence: charm, strange, top, and bottom.

The flavours of quarks are up, down, top (or truth), bottom (or beauty), charm and strange. Physics gets weirder the smaller you go.

Matter is made up of quarks: protons, neutrons, and quarks are the basic components of all matter. There are six quarks overall, which are separated into three pairs (or families). They're up/down, charm/strange, and top/bottom. QUARKS’ TYPES. Up, down, top, bottom, weird, and appeal are the six varieties. Some Important terms of 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. This is because the transformation proceeds by the exchange of charged W bosons, which must change the charge by one unit. The general pattern is that the quarks will decay to the most massive quark ... The 12 elementary particles of matter are six quarks (up, charm, top, Down, Strange, Bottom) 3 electrons (electron, muon, tau) and three neutrinos (e, muon, tau).
