Annual Review of Nuclear and Particle Science, 1980 The author reviews the experimental knowledge of the properties of the tau lepton and the tau neutrino. The conventional theory of lepton properties and interactions is summarized; and that theory is compared with experiment. Future directions for research in tau and tau neutrino physics are described.

Search for medium response to jet quenching via hadron chemistry around the quenched jets [PDF]
EPJ Web of ConferencesWe present a unique signal of medium response to jet quenching: the enhancement of baryon-to-meson ratios for associated particles at intermediate transverse momentum around the triggered quenched jets.

CP asymmetry in the angular distribution of τ → KS πν τ decays
Journal of High Energy Physics, 2020 In this work, we study the C P asymmetry in the angular distribution of τ → K S πν τ decays, taking into account the known C P violation in K 0 − K ¯ 0 $$ {K}^0-{\overline{K}}^0 $$ mixing. It is pointed out for the first time that, once the well-measured

Leptonic decays of the tau lepton [PDF]
EPJ Web of Conferences, 2019 In these proceedings we review the SM prediction for the tau leptonic decays, including the radiative $ (\tau \to \ell \lambda \nu \bar \nu ) $ and the five-body $ (\tau \to \ell \ell '\ell '\nu \bar \nu ) $ decay modes, which are among the most powerful tools to study precisely the structure of the weak interaction and to constrain possible ...

Leptonic and semi-leptonic B decays [PDF]
Nuclear Physics B - Proceedings Supplements, 2001 We present results for the semi-leptonic and leptonic decays of B mesons. These non-perturbative matrix elements are important for constraining the CKM matrix. Results are presented for the pseudoscalar and vector decay constants, as well as flavour breaking ratios and heavy quark symmetry relations.

Freeze-in Dirac neutrinogenesis: thermal leptonic CP asymmetry
European Physical Journal C: Particles and Fields, 2020 We present a freeze-in realization of the Dirac neutrinogenesis in which the decaying particle that generates the lepton-number asymmetry is in thermal equilibrium.

Probing new physics in class-I B-meson decays into heavy-light final states
Journal of High Energy Physics, 2021 With updated experimental data and improved theoretical calculations, several significant deviations are being observed between the Standard Model predictions and the experimental measurements of the branching ratios of B ¯ s 0 → D s ∗ + L ...

Softly broken lepton numbers and maximal neutrino mixing [PDF]
, 2001 We consider lepton mixing in an extension of the Standard Model with three right-handed neutrino singlets. We require that the three lepton numbers L_e, L_\mu, and L_\tau be separately conserved in the Yukawa couplings, and we assume that they are softly

Physics Letters B, 1996 It is assumed that three lepton families $( _e, e)$, $( _ , )$, $( _ , )$ carry charges, which are sources of electronic, muonic and tauonic massless vector particles, respectively. Various manifestations of these hypothetical photons are discussed.
