Search for New Physics Beyond the Standard Model at BaBar
A review of selected recent BaBar results are presented that illustrate the ability of the experiment to search for physics beyond the standard model. The decays B→ τν and B→ sγ provide constraints on the mass of a charged Higgs. Searches for Lepton Flavour Violation could provide a clear signal for beyond the standard model physics. Babar does not observe any signal for New Physics with the cu...
متن کاملStandard Model Stability Bounds for New Physics within Lhc Reach
We analyse the stability lower bounds on the Standard Model Higgs mass by carefully controlling the scale independence of the effective potential. We include resummed leading and next-to-leading-log corrections, and physical pole masses for the Higgs boson, MH , and the top-quark, Mt. Particular attention is devoted to the cases where the scale of new physics Λ is within LHC reach, i.e. Λ ≤ 10 ...
متن کاملThe Standard Model Instability and the Scale of New Physics *
We apply a general formalism for the improved effective potential with several mass scales to compute the scale M of new physics which is needed to stabilize the Standard Model potential in the presence of a light Higgs. We find, by imposing perturbativity of the new physics, that M can be as large as one order of magnitude higher than the instability scale of the Standard Model. This implies t...
متن کاملNew Physics Beyond the Standard Model with Weakly Interacting Particles
In this thesis, two of the most exciting areas in high energy physics nowadays are studied: neutrino physics and collider physics, which play important roles in the intensity and energy frontiers, respectively. For neutrino physics, assuming that the neutrino mass matrix is dominated by a term with the permutation symmetry S3, it is possible to explain neutrino data only if the masses are quasi...
متن کاملNew Physics behind the Standard Model ’ s door ? ∗
We review the main reasons pushing us beyond the SM and we argue in favor of new physics at the electroweak scale (hence experimentally accessible at present or near–future machines). We focus on the appealing possibility that such new physics is given by a super-symmetric (SUSY) extension of the SM. We discuss the minimal case, Constrained Minimal Supersymmetric SM, and more general (maybe mor...
