Probe New Physics in Leptonic Bc Decays at CERN LHC
With respect to large samples of Bc mesons expected to be produced at CERN Large Hadron Collider(LHC) and the large branching ratios Br(Bc → τ ν̄) and Br(Bc → μν̄), we suggest that Bc purely leptonic decays could offer an unique probe of the standard model and its extensions such as two Higgs doublet models and models involving supersymmetry, and also the structure of charged weak currents. PACS ...
متن کاملHiggs Triplet Effects in Purely Leptonic Processes
We consider the effect of complex Higgs triplets on purely leptonic processes and survey the experimental constraints on the mass and couplings of their single and double charge members. Present day experiments tolerate values of the Yukawa couplings of these scalars at the level of the standard electroweak gauge couplings. We show that the proposed measurement of the ratio R LCD = σ(ν µ e)/[σ(...
متن کاملNew Physics Effects in B Decays
The two B-factories, Belle [1] and BaBar [2], has been played major roles in the B decays study. Their wonderful design and excellent operation enables their fruitful analysis results. Also recently the Tevatron experiments, CDF and DØ, join the game with their BS studies. From the experimental results of B decay studies, we learn that most of measurements are consistent with the Standard Model...
متن کاملNew physics effects in rare Z decays
Virtual effects induced by new physics in rare Z decays are reviewed. Since the expected sensitivity of the giga–Z linear collider is of the order of 10, we emphasize the importance of any new physics effect that gives a prediction above this limit. It is also pointed out that an improvement on the known experimental constraints on rare Z decays will provide us with a critical test of the valid...
متن کاملUniversality-breaking effects in leptonic Z decays.
We analyze the possibility of universality violation in diagonal leptonic decays of the Z boson, in the context of interfamily ”see-saw” models. In a minimal extension of the Standard Model with right-handed neutrino fields, we find that universality-breaking effects increase quadratically with the heavy Majorana neutrino mass and may be observed in the running LEP experiments. PACS numbers: 12...
