To this purpose, we calculate the two-loop contributions to the gg → hh amplitudes that involve a … WebIn quantum field theory, a quartic interaction is a type of self-interaction in a scalar field. Other types of quartic interactions may be found under the topic of four-fermion …
Web24 de jun. de 2024 · We present a simple mechanism for generating a Higgs quartic in composite Higgs models without a corresponding quadratic term. This quartic term will originate from a Higgs dependent kinetic mixing between additional fermionic states. The mechanism can be naturally embedded to models with maximal symmetry as well as … WebThe Higgs quartic coupling at the two-loop level constrains the leptoquark Yukawa couplings for R~2,S3,R~2+S3 with values with three generations. In the effective potential approach, the...
WebThis Higgs-fermion coupling was first described by Steven Weinberg in 1967 to model lepton masses.
