Predictions and Tests for Semi-leptonic Decays of Beauty Hadrons,

Elvio Di Salvo, Ziad J. Ajaltouni, Flavio Fontanelli

We make predictions and propose tests for the semi-leptonic decays $B \to D^{(*)} l ν ˉ_{l}$ and $Λ_{b} \to Λ_{c} l ν ˉ_{l}$ , with $l$ = $e$ , $μ$ and $τ$ . Preliminarily, we study such pr…

Searching for New Physics in the Differential Decay Width of a Lambda_b Semi-leptonic Decay

E. Di Salvo, Z. J. Ajaltouni

We propose to investigate the effects of new physics in the semi-leptonic sequential decay $Λ_{b} \to Λ_{c} (\to Λ π) τ ν ˉ_{τ}$ . Firstly, we write the general, model independent, non…

Parametrizations of the Spin Density Matrix

Elvio Di Salvo, Ziad Jean Ajaltouni

We propose for the spin density matrix two parametrizations which automatically fulfil the non-negativity conditions, without setting any bound on the parameters. The first one rel…

Observation of two resonances in the $Λ_{b}^{0} π^{\pm}$ systems and precise measurement of $Σ_{b}^{\pm}$ and $Σ_{b}^{*\pm}$ properties

LHCb collaboration, R. Aaij, C. Abellán Beteta +837

The first observation of two structures consistent with resonances in the final states $Λ_{b}^{0} π^{-}$ and $Λ_{b}^{0} π^{+}$ is reported using samples of $pp$ collision data collected by the…

Central exclusive production of $J / ψ$ and $ψ (2 S)$ mesons in $pp$ collisions at $s = 13$ TeV

LHCb collaboration, R. Aaij, B. Adeva +808

Measurements are reported of the central exclusive production of \jpsi and \psitwos mesons in $pp$ collisions at a centre-of-mass energy of 13 TeV. Backgrounds are significantly re…

Detailed Study of the Decay Lambda_b --> Lambda_c tau {\bar ν}_τ

E. Di Salvo, F. Fontanelli, Z. J. Ajaltouni

We examine in detail the semi-leptonic decay $Λ_{b} \to Λ_{c} τ ν ˉ_{τ}$ , which may confirm previous hints, from the analogous $B$ decay, of a new physics beyond the standard model.…
