WebThese models contain additional scalars. The simplest models contain a color singlet and a colored sextet. For such a baryon number violation to be observed in experiments, the scalars cannot be much heavier than a few tera-electron-volts. We find that such models are strongly constrained by LHC physics, LEP physics, and flavor physics. WebBaryon number conservation: Protons and neutrons are examples of baryons. Electrons, photons and neutrinos have no baryon number. The number of baryons must be the …

In particle physics, a baryon is a type of composite subatomic particle which contains an odd number of valence quarks (at least 3). Baryons belong to the hadron family of particles; hadrons are composed of quarks. Baryons are also classified as fermions because they have half-integer spin. The name "baryon", … Meer weergeven Baryons are strongly interacting fermions; that is, they are acted on by the strong nuclear force and are described by Fermi–Dirac statistics, which apply to all particles obeying the Pauli exclusion principle. … Meer weergeven Experiments are consistent with the number of quarks in the universe being a constant and, to be more specific, the number of … Meer weergeven Baryons are classified into groups according to their isospin (I) values and quark (q) content.

This is one of the indicators for whether an interaction is able to occur or not. The baryon number of a particle depends if it is a baryon, anti–baryon or neither. …

WebAstronomers therefore use the term ‘baryonic’ to refer to all objects made of normal atomic matter, essentially ignoring the presence of electrons which, after all, represent only ~0.0005 of the mass. Neutrinos, on the other hand, are (correctly) considered non-baryonic by astronomers. Webbe produced is the electron. That takes care of mass-energy and charge. For baryon number, the neutron and the proton each have B = +1, and the electron has B = 0, so that balances fine. Check. But -- the neutron has a lepton number of zero, and so does the proton, but the electron has a lepton number of +1. Ouch.
