The $Λ_{c} \to Λ l^{+} ν_{ℓ}$ weak decay including new physics

Fernando Alvarado, Luis Alvarez-Ruso, Eliecer Hernandez +2

We investigate the $Λ_{c} \to Λ ℓ^{+} ν_{ℓ}$ decay with a focus on potential new physics (NP) effects in the $ℓ = μ$ channel. We employ an effective Hamiltonian within the fram…

New physics effects on $Λ_{b} \to Λ_{c}^{*} τ ν ˉ_{τ}$ decays

Meng-Lin Du, Neus Penalva, Eliecer Hernández +1

We benefit from a recent lattice determination of the full set of vector, axial and tensor form factors for the $Λ_{b} \to Λ_{c}^{*} (2595) τ ν ˉ_{τ}$ and $Λ_{c}^{*} (2625) τ ν ˉ_{τ}$ semileptonic…

Visible energy and angular distributions of the charged particle from the $τ -$ decay in $b \to c τ (μ ν ˉ_{μ} ν_{τ}, π ν_{τ}, ρ ν_{τ}) ν ˉ_{τ}$ reactions

N. Penalva, E. Hernández, J. Nieves

We study the $d^{2} Γ_{d} / (d ω d cos θ_{d})$ , $d Γ_{d} / d cos θ_{d}$ and $d Γ_{d} / d E_{d}$ distributions, which are defined in terms of the visible energy and polar angle of the charged particle f…

The role of right-handed neutrinos in $b \to c τ (π ν_{τ}, ρ ν_{τ}, μ ν ˉ_{μ} ν_{τ}) ν ˉ_{τ}$ from visible final-state kinematics

N. Penalva, E. Hernández, J. Nieves

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-p…

$B ˉ_{c} \to η_{c}$ , $B ˉ_{c} \to J / ψ$ and $B ˉ \to D^{(*)}$ semileptonic decays including new physics

N. Penalva, E. Hernández, J. Nieves

We apply the general formalism derived in N. Penalva et al. [Phys. Rev. D 101, 113004 (2020)] to the semileptonic decay of pseudoscalar mesons containing a $b$ quark. While present…

Hadron and lepton tensors in semileptonic decays including new physics

N. Penalva, E. Hernández, J. Nieves

We extend our general framework for semileptonic decay, originally introduced in N. Penalva et al. [Phys. Rev. D100, 113007 (2019)], with the addition of new physics (NP) tensor te…
