Measurements of the Absolute Branching Fractions of $B^{\pm} \to K^{\pm} X_{c c ˉ}$

J. P. Lees, V. Poireau, V. Tisserand +232

A study of the two body decays $B^{\pm} \to X_{c c ˉ} K^{\pm}$ , where X $_{c c ˉ}$ refers to one charmonium state, is reported by BaBar collaboration using a data sample of 42…

Tracking performance for long-lived particles at LHCb

Luis Miguel Garcia, Louis Henry, Brij Jashal +1

The LHCb experiment is dedicated to the study of the $c -$ and $b -$ hadron decays, including long-lived particles such as $K_{s}$ and strange baryons ( $Λ^{0}$ , $Ξ^{-}$ , etc... ). These kin…

Search for the doubly charmed baryon $Ξ_{cc}^{+}$

LHCb collaboration, R. Aaij, C. Abelán Beteta +905

A search for the doubly charmed baryon $Ξ_{cc}^{+}$ is performed through its decay to the $Λ_{c}^{+} K^{-} π^{+}$ final state, using proton-proton collision data collected with the LHCb de…

Search for $B^{-} \to Λ p ˉ ν ν ˉ$ with the BABAR experiment

The BABAR Collaboration, J. P. Lees, V. Poireau +235

We search for the rare flavor-changing neutral current process $B^{-} \to Λ p ν ν$ using data from the BABAR experiment. A total of 424 fb $^{- 1}$ of $e^{+} e^{-}$ col…

Radiative $b$ -baryon decays to measure the photon and $b$ -baryon polarization

Luis Miguel García Martín, Brij Jashal, Fernando Martínez Vidal +4

The radiative decays of $b$ -baryons facilitate the direct measurement of photon helicity in $b \to s γ$ transitions thus serving as an important test of physics beyond the Standard M…
