Take your pick of the Standard Model’s shortcomings: almost all of them motivate the search for additional Higgs bosons. Their properties are usually assumed to be simple. Much as the 125 GeV Higgs ...
For 16 years, scientists hypothesized the existence of a quasi-particle called a semi-Dirac fermion, named after mathematician Paul Dirac whose eponymous equation describes these fermions.
A general quantum field theory is considered in which the fields are assumed to be operator‐valued tempered distributions. The system of fields may include any number of boson fields and fermion ...
