LHCb Collaboration; Adeva Andany, Bernardo; Dosil Suárez, Álvaro; Fernández Albor, Víctor Manuel; Gallas Torreira, Abraham Antonio; García Pardiñas, Julián; Lemos Cid, Edgar; Lucio Martínez, Miriam; Martínez Santos, Diego; Plo Casasus, Máximo; Romero Vidal, Antonio; Saborido Silva, Juan José; Santamarina Ríos, Cibrán; Vázquez Regueiro, Pablo; Vázquez Sierra, Carlos; Vieites Díaz, María; Sanmartín Sedes, Brais (Springer, 2015)

The first measurement of CP asymmetries in the decay B0s→J/ψK∗(892)0 and an updated measurement of its branching fraction and polarisation fractions are presented. The results are obtained using data corresponding to an ...

LHCb Collaboration; Adeva Andany, Bernardo; Álvarez Cartelle, Paula; Dosil Suárez, Álvaro; Fernández Albor, Víctor Manuel; Gallas Torreira, Abraham Antonio; García Pardiñas, Julián; Hernando Morata, José Ángel; Pazos Álvarez, Antonio; Pérez Trigo, Eliseo; Plo Casasus, Máximo; Romero Vidal, Antonio; Saborido Silva, Juan José; Sanmartín Sedes, Brais; Santamarina Ríos, Cibrán; Seco Miguélez, Marcos Antonio; Vázquez Regueiro, Pablo; Vázquez Sierra, Carlos; Vieites Díaz, María (Springer, 2014)

We report on measurements of the time-dependent CP violating observables in B 0s → D ∓s K ± decays using a dataset corresponding to 1.0 fb−1 of pp collisions recorded with the LHCb detector. We find the CP violating ...

Measurement of the CKM angle γ using B ± → DK ± with D → K0S π + π −, K0S K + K − decays

LHCb Collaboration; Adeva Andany, Bernardo; Álvarez Cartelle, Paula; Fernández Albor, Víctor Manuel; Gallas Torreira, Abraham Antonio; García Pardiñas, Julián; Hernando Morata, José Ángel; Pazos Álvarez, Antonio; Pérez Trigo, Eliseo; Plo Casasus, Máximo; Romero Vidal, Antonio; Saborido Silva, Juan José; Sanmartín Sedes, Brais; Santamarina Ríos, Cibrán; Seco Miguélez, Marcos Antonio; Vázquez Regueiro, Pablo; Vázquez Sierra, Carlos; Vieites Díaz, María (Springer, 2014)

A binned Dalitz plot analysis of B± → DK± decays, with D → K0S + − and D → K0S K+K−, is performed to measure the CP-violating observables x± and y±, which are sensitive to the Cabibbo-Kobayashi-Maskawa angle . The ...

Observation of the Λ0b → J/ψ pπ − decay

LHCb Collaboration; Adeva Andany, Bernardo; Álvarez Cartelle, Paula; Dosil Suárez, Álvaro; Fernández Albor, Víctor Manuel; Gallas Torreira, Abraham Antonio; Hernando Morata, José Ángel; Pazos Álvarez, Antonio; Pérez Trigo, Eliseo; Plo Casasus, Máximo; Romero Vidal, Antonio; Saborido Silva, Juan José; Sanmartín Sedes, Brais; Santamarina Ríos, Cibrán; Seco Miguélez, Marcos Antonio; Vázquez Regueiro, Pablo; Vázquez Sierra, Carlos; Vieites Díaz, María (Springer, 2014)

The first observation of the Cabibbo-suppressed decay Λ 0b → J/ψpπ − is reported using a data sample of proton-proton collisions at 7 and 8 TeV, corresponding to an integrated luminosity of 3 fb−1. A prominent signal is ...

Measurement of the time-dependent CP asymmetries in B0s → J/ψK0S

The first measurement of decay-time-dependent CP asymmetries in the decay B0s → J/ψK0S and an updated measurement of the ratio of branching fractions B(B0s→J/ψK0S)/B(B0→J/ψK0S)are presented. The results are obtained using ...
