The Pair Production of Quarks

R. Marshall

Abstract: A brief overview of the history of e+ annihilation is presented, from the first days in the 1950s up to the start of PETRA in 1978. The pre-LEP situation on R measurements is reviewed, followed by a description of how the b-quark measurements at PETRA showed that the t-quark must exist.

The theoretic model explains the generating of heavy quarks and of heavy particles using the known quark s(strange) and two semi-light quarks: λ±(435 MeV) and v±(∼574 MeV) resulting from a cold genesis theory1 of astro-particles’ forming, (CGT), the masses of the quarks c• (charm) and b• (bottom) of the Standard Model but also the values used by de Souza: c = 1.7 GeV and b = 5 GeV, being re-obtained as tri-quark clusters in the form: [(qq¯)q]], by a simple de-excitation reaction, with the emission of a preonic boson obtained in CGT: z0 = 34me, respective: z2 = 4z0 and zμ = 6z0- for the quarks b• and b. A similar de-excitation reaction, with emission of a preonic boson zk = n⋅z0, (n = 1÷7), representing less than 2.7% from the particle’s mass, explains the experimentally obtained masses of heavy baryons and mesons and of some multi-quark particles, with discrepancy <1% generally. The heavy current quarks result by lighter current quarks with quasi-crystalline internal structure, with trigonal/hexagonal symmetry of preonic kernels of two preonic bosons: z2 = 4z0; zπ = 7z0, the top-quark resulting as: t = 17(bb¯) + b = (7x5)⋅m(b), with a kernel of regular hexagonal polyhedron form, given by kernels of b-quarks. The model is compatible with the generation model and explains the quarks pairs forming from relativist e−- e+ jets.
