Measurement of the Λb0 → Λ(1520)μ+μ- Differential Branching Fraction

Lesya Shchutska, Olivier Schneider, Aurelio Bay, Guido Haefeli, Frédéric Blanc, Tatsuya Nakada, Michel De Cian, Elena Graverini, Renato Quagliani, Aravindhan Venkateswaran

The branching fraction of the rare decay Lambda(0 )(b)-> Lambda(1520)mu(+)mu(-) is measured for the first time, in the squared dimuon mass intervals q(2), excluding the J/psi and psi(2S) regions. The data sample analyzed was collected by the LHCb experimen ...

Lesya Shchutska, Olivier Schneider, Aurelio Bay, Guido Haefeli, Frédéric Blanc, Tatsuya Nakada, Michel De Cian, Elena Graverini, Renato Quagliani, Aravindhan Venkateswaran

Jet fragmentation functions are measured for the first time in proton-proton collisions for charged pions, kaons, and protons within jets recoiling against a Z boson. The charged-hadron distributions are studied longitudinally and transversely to the jet d ...
