Vacuum structure of the left-right symmetric model

+ in the Left - Right Symmetric Model

A novel left - right symmetric model

A novel gauge model which has a spontaneously broken parity symmetry is constructed. The model has only 2 parameters beyond those of the standard model. Some of the unusual implications of the model are discussed. 1 Email: [email protected] The standard model of particle physics (SM) is an extremely successful description of past and existing experiments. At present there is no experim...

The Number of Neutrinos and the Left - Right Symmetric Model

The meaning of Nν in the Left-Right Symmetric Model (LRSM) is discussed. In its original definition Nν is the number of neutrinos or generations of leptons, so, in the Standard Model its value is three. However the determination of Nν in experiments and in astrophysical observations is subject to different theoretical interpretations. We present arguments that gives Nν as a parameter of the LRS...

Higgs sector of the minimal left-right symmetric model

We perform an exhaustive analysis of the most general Higgs sector of the minimal left-right symmetric model ~MLRM!. We find that the CP properties of the vacuum state are connected to the Higgs spectrum: if CP is broken spontaneously, the MLRM does not approach the standard model in the limit of a decoupling left-right symmetry breaking scale. Depending on the size of the CP phases, scenarios ...

B + S42+!-in the Left-right Symmetric Model A

We begin to analyze and contrast the predictions for the decay b + sP+!-in the Left-Right Symmetric Model(LRM) with those of the Standard Model(SM). In particular, we show that the forward-backward asymmetry of the lepton spectrum can be used to distinguish the SM from the simplest manifestation of the LRM.
