“…Only a left-handed NP term would not give rise to any T -odd effect. In this connection, we observe that, if the decay Λ b → Λ c τν τ confirms the anomaly found in the semi-leptonic decay of B [7,8,9], a zero value for any of the above-mentioned T -odd observables would be an indication in favor of a V − A NP contribution [66]. B) Such observables may imply also TRV; unlike other measurements which were suggested [32] few years ago, this implication is independent of the CP T theorem.…”

“…Therefore it is essential to realize experiments where, either a clear contradiction with the SM is found, or at least more stringent constraints on physics beyond it are established. Indeed, in the past few years, some data concerning semi-leptonic decays exhibited strong tensions with the SM predictions [7][8][9][10][11].…”

We consider two-body and quasi-two-body decays of the type f 1 → f 2 B, where f 1 and f 2 are spin-1/2 fermions and B a spin-0 or spin-1 boson. After recalling the non-covariant formalism for decay amplitudes, we derive the expression of the differential decay width and of the polarizations of the final spinning particles, both onand off-shell. We find an intriguing geometrical interpretation of the results about the polarization. We also illustrate some methods for measuring the polarizations of the resonances and for optimizing data analysis. Then we propose applications to semi-leptonic weak decays, with a major attention to the T -odd component of the polarization; this may help to find, simultaneously, possible time-reversal violations and hints to physics beyond the standard model. We suggest also a CP T test. Last, we discuss some T -odd observables for the production process of f 1 and for the study of the strong final state interactions of non-leptonic decays.

Recent investigations have suggested that the singlet six-quark combination uuddss may be a deeply bound state S, called Sexaquark. An essentially stable state S is a potentially excellent Dark Matter candidate. We present the first search for a stable, doubly strange sixquark state in the decays of Υ(4S) → ΛΛ. Based on a data sample of Υ(2S) and Υ(3S) decays collected by the BABAR Experiment we report the most recent results and set stringent limits on the existence of such exotic particle.

Higgs boson decay h → Zγ and muon magnetic dipole moment in the μνSSM

To solve the µ problem and generate three tiny neutrino masses in the MSSM, the µ from ν Supersymmetric Standard Model (µνSSM) introduces three singlet right-handed neutrino superfields, which lead to the mixing of the Higgs doublets with the sneutrinos. The mixing affects the lightest Higgs boson mass and the Higgs couplings. The present observed 95% CL upper limit on signal strength of the 125 GeV Higgs boson decay h → Zγ is 6.6, which still is plenty of space to prove the existence of new physics. In this work, we investigate the signal strength of the 125 GeV Higgs boson decay channel h → Zγ in the µνSSM. Besides, we consider the two-loop electroweak corrections of muon anomalous magnetic dipole moment (MDM) in the model, which also make important contributions compared with one-loop electroweak corrections.
