Definition of baryon
WebMay 22, 2024 · Each baryon has a baryon number of 1 and each antibaryon has a baryon number of -1. Other non-baryonic particles have a baryon number of 0. Since there are exotic hadrons like pentaquarks and tetraquarks, there is a general definition of baryon number as: where n q is the number of quarks, and n q is the number of antiquarks. WebAug 17, 2016 · The ratio of baryons to photons or the baryon abundance is defined as: n ≡ N b N γ ≃ 2.75 × 10 − 8 Ω b h 2. where N b is the number density of baryons, and N γ = 4.11 × 10 8 m − 3 is the number density of photons. Thus the primordial abundances of baryonic matter in the standard Big Bang nucleosynthesis scenario (BBN) is ...
