Webb27 sep. 2024 · Quark Rules of Thumb. One of the few theorists to foresee why two charm quarks might mingle was Jean-Marc Richard, now at the Institute of Physics of the 2 Infinities in Lyon, France. In 1982, he and two colleagues studied a simple quark model and initially found that four quarks would rather form two pairs — mesons. WebbFrom SU(3) to SU(6) and to the quark model.-The subsequent step which, although not logically necessary, has been important for the construction of the nonrelativistic quark model was the idea [due to Gursey & Radicati (21) and Sakita (22)] of the SU(6) invariance and the failure to obtain a relativ istic formulation of this symmetry.

Webb13 okt. 2024 · In the quark model, the wave function of a baryon contains three constituent quarks. The wave function is the product of four parts describing the spatial, spin, flavor, and color configuration. The Pauli principle requires the baryon to be antisymmetric with respect to the exchange of any pair of quarks.
