Abstract We investigate the Λ c → Λℓ + ν ℓ decay with a focus on potential new physics (NP) effects in the ℓ = μ channel. We employ an effective Hamiltonian within the framework of the Standard Model Effective Field Theory (SMEFT) to cons

Abstract We benefit from the lattice QCD determination by the HPQCD of the Standard Model (SM) form factors for the B ¯ s → D s $$ {\overline{B}}_s\to {D}_s $$ [Phys. Rev. D 101 (2020) 074513] and the SM and tensor ones for the B ¯ s → D s ∗

Abstract We study the d 2Γ d /(dωd cos θ d ), dΓ d /d cos θ d and dΓ d /dE d distributions, which are defined in terms of the visible energy and polar angle of the charged particle from the τ −decay in b → cτ μ ν ¯ μ ν τ πν τ ρ

Abstract In the context of lepton flavor universality violation (LFUV) studies, we fully derive a general tensor formalism to investigate the role that left- and right-handed neutrino new-physics (NP) terms may have in b → cτ ν ¯ $$ \overline{\n

For a general H_b→H_c τ ν_τ decay, we analyze the role of theτpolarization vector P^μ in the context of lepton flavor universality violation studies. We use a general phenomenological approach that includes several new physics terms and we mak
