Shedding light on the $X (3930)$ and $X (3960)$ states with the $B^{-} \to K^{-} J / ψ ω$ reaction

L. M. Abreu, M. Albaladejo, A. Feijoo +2

We have studied the contribution of the state $X (3930)$ , coming from the interaction of the $D D$ and $D_{s}^{+} D_{s}^{-}$ channels, to the $B^{-} \to K^{-} J / ψ ω$ decay. The pu…

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…

Tau longitudinal and transverse polarizations from visible kinematics in (anti-)neutrino nucleus scattering

E. Hernández, J. Nieves, F. Sánchez +1

Since the $ν_{τ} (ν ˉ_{τ}) A_{Z} \to τ^{\mp} X$ reaction is notoriously difficult to be directly measured, the information on the dynamics of this nuclear process should be extracted from…

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…

New physics and the tau polarization vector in $b \to c τ ν ˉ_{τ}$ decays

N. Penalva, E. Hernández, J. Nieves

For a general $H_{b} \to H_{c} τ ν ˉ_{τ}$ decay we analyze the role of the $τ$ polarization vector $P^{μ}$ in the context of lepton flavor universality violation studies. We use a ge…

$D D ˉ^{*}$ scattering and $χ_{c 1} (3872)$ in nuclear matter

M. Albaladejo, J. M. Nieves, L. Tolos

We study the behaviour of the $χ_{c 1} (3872)$ , also known as $X (3872)$ , in dense nuclear matter. We begin from a picture in vacuum of the $X (3872)$ as a purely molecular $(D \bar D^…
