Observation of J/psi-pair production in pp collisions at root s=7 TeV

Jian Wang, Olivier Schneider, Yi Zhang, Lei Zhang, Aurelio Bay, Guido Haefeli, Jessica Prisciandaro, Tatsuya Nakada, Christoph Frei, Mark Tobin, Frédéric Blanc, Minh Tâm Tran, Michel De Cian, Greig Alan Cowan, Vladislav Balagura, Plamen Hristov Hopchev, Frédéric Guillaume Dupertuis, Julien Rouvinet, Christophe Salzmann, Pierre Jaton, Barinjaka Rakotomiaramanana, Joël Bressieux, Raluca Anca Muresan, Johan Luisier, Albert Puig Navarro, Anne Keune, Vincent Fave, Christophe Bauer, Mathias Oleg Knecht, Neal Gauvin

The production of J/psi pairs in proton-proton collisions at a centre-of-mass energy of 7 TeV has been observed using an integrated luminosity of 37.5 pb(-1) collected with the LHCb detector. The production cross-section for pairs with both J/psi in the ra ...

Observation of (B)over-bar(s)(0) -> J/psi f '(2)(1525) in J/psi K(+)K(-)Final States

Jian Wang, Olivier Schneider, Yi Zhang, Lei Zhang, Aurelio Bay, Guido Haefeli, Jessica Prisciandaro, Tatsuya Nakada, Christoph Frei, Mark Tobin, Frédéric Blanc, Minh Tâm Tran, Michel De Cian, Greig Alan Cowan, Vladislav Balagura, Plamen Hristov Hopchev, Bastien Luca Muster, Frédéric Guillaume Dupertuis, Julien Rouvinet, Christophe Salzmann, Pierre Jaton, Barinjaka Rakotomiaramanana, Joël Bressieux, Raluca Anca Muresan, Johan Luisier, Albert Puig Navarro, Anne Keune, Vincent Fave, Christophe Bauer, Mathias Oleg Knecht, Neal Gauvin

The decay (B) over bar (0)(s) (->) J/psi K+K- is investigated using 0:16 fb(-)1 of data collected with the LHCb detector using 7 TeV pp collisions. Although the J/00 psi phi channel is well known, final states at higher K+K- masses have not previously been ...

Precision measurement of the B-s(0)-(B)over-bar(s)(0) oscillation frequency with the decay B-s(0) -> D-s(-)pi(+)

Jian Wang, Olivier Schneider, Yiming Li, Yi Zhang, Lei Zhang, Aurelio Bay, Guido Haefeli, Jessica Prisciandaro, Tatsuya Nakada, Christoph Frei, Mark Tobin, Frédéric Blanc, Minh Tâm Tran, Michel De Cian, Greig Alan Cowan, Maurizio Martinelli, Vladislav Balagura, Donal Patrick Hill, Jean Wicht, Ilya Komarov, Plamen Hristov Hopchev, Bastien Luca Muster, Frédéric Guillaume Dupertuis, Julien Rouvinet, Christophe Salzmann, Pierre Jaton, Barinjaka Rakotomiaramanana, Joël Bressieux, Songmei Wu, Raluca Anca Muresan, Johan Luisier, Anne Keune, Vincent Fave

A key ingredient to searches for physics beyond the Standard Model in B-s(0) mixing phenomena is the measurement of the B-s(0)-(B) over bar (0)(s) oscillation frequency, which is equivalent to the mass difference Delta m(s) of the B-s(0) mass eigenstates. ...
