26. LHC phenomenology of general SU(2)xSU(2)xU(1) models

M. Tomas Jezo (LPSC)

General SU(2)xSU(2)xU(1) models represent a well-motivated intermediate step towards the unification of the Standard Model gauge groups. Based on a recent global analysis of low-energy and LEP constraints of these models, we perform numerical scans of their various signals at the LHC. We show that total cross sections for lepton and third-generation quark pairs, while experimentally easily...

20. Baryon and lepton number violation at the LHC

Dr Christopher Smith (IPN Lyon)

16/05/2012 11:30

Baryon (B) and lepton (L) numbers are conserved in the standard model lagrangian, but generally not in new physics models. In this talk, we adopt an effective approach to analyze, in a model-independent way, the possible signatures of B and L violating interactions at the LHC. Then, we particularize the discussion to the minimal supersymmetric standard model, where such interactions may now be...

4. Unlocking the Standard Model : the 1-generation case

Dr Bruno Machet (CNRS)

16/05/2012 11:55

I show that the Standard Model of weak interactions cannot have less than two Higgs doublets as soon as they are considered (to transform) as $\bar q_i q_j$ and $\bar q_i \gamma_5 q_j$ bilinears. There are exactly two for one generation of quarks, which is the simple case under scrutiny here. All basic physical properties, not only of massive gauge bosons, but also of fermions and J=0 mesons...
