Scattering with Baryon Number Violation: The Case of Higgs Particle Production

Baryon Number Violation in Particle Decays

It has been argued in the past that in baryogenesis via out-of-equilibrium decays one must consider loop diagrams that contain more than one baryon number violating coupling. In this note we argue that the requirement with regard to baryon number violating couplings in loop diagrams is that the interaction between the intermediate on-shell particles and the final particles should correspond to ...

2002 Electroweak Baryon Number Violation

The conditions for baryogenesis in the early universe are well-known (cf. Refs. [1, 2]): 1. C and CP violation, 2. thermal nonequilibrium, 3. violation of baryon number conservation. How realistic are these requirements? Well, noninvariance under the charge conjugation transformation (C) and the combined charge conjugation and parity reflection transformation (CP) have been observed in the labo...

Higgs boson decays, baryon number violation, and supersymmetry at the LHC

Baryon number violating interactions could modify the signatures of supersymmetric models at the Large Hadron Collider. In this article we investigate the predictions for the Higgs mass and the Higgs decays in a simple extension of the minimal supersymmetric standard model where the local baryon and lepton numbers are spontaneously broken at the TeV scale. This theory predicts baryon number vio...

The electroweak phase structure and baryon number violation for Large Higgs Mass

The electroweak phase structure and baryon number violation for large Higgs mass. The classical transitions between topologically distinct vacua in a SU (2)–Higgs model, using a Higgs field of mass approximately 120 GeV, is examined to probe the crossover region between the symmetric and broken phase. For the volumes used, this crossover is approximately 10 GeV wide.
