Invisible decays of vector Charmonia and Bottomonia to determine the Weak Mixing Angle at quarkonia scale

G. Hernández-Tomé, C. S. Kim, G. López Castro

We compute the branching fractions of vector quarkonia ( $V_{Q} = J / ψ, ψ^{'}, Υ (n S)$ ) decays into neutrino pairs, considering both Dirac and Majorana types, within the Standard Model (SM)…

Non-standard interactions in $τ^{-} \to (π^{-} η, π^{-} π^{0}) ν_{τ}$ decays

G. López Castro

Originally thought as clean processes to study the hadronization of the weak currents, semileptonic tau lepton decays can be useful to set constraints on non-standard (NS) weak int…

Constraints on a sub-eV scale sterile neutrino from non-oscillation measurements

C. S. Kim, G. López Castro, Dibyakrupa Sahoo

Anomalies in several short-baseline neutrino oscillation experiments suggest the possible existence of sterile neutrinos at about eV scale having appreciable mixing with the alread…

Discovering intermediate mass sterile neutrinos through $τ^{-} \to π^{-} μ^{-} e^{+} ν$ (or $ν ˉ$ ) decay

C. S. Kim, G. López Castro, Dibyakrupa Sahoo

Distinguishing the Dirac and Majorana nature of neutrinos remains one of the most important tasks in neutrino physics. By assuming that the $τ^{-} \to π^{-} μ^{-} e^{+} ν$ (or $ν ˉ$ ) dec…

Effective-field theory analysis of the $τ^{-} \to η^{(')} π^{-} ν_{τ}$ decays

E. A. Garcés, M. Hernández Villanueva, G. López Castro +1

The rare $τ^{-} \to η^{(')} π^{-} ν_{τ}$ decays, which are suppressed by $G$ -parity in the Standard Model (SM), can be sensitive to the effects of new interactions. We study the sen…
