Search for Invisible Decays of a Dark Photon Produced in e+e- Collisions at BaBar

J. P. Lees

We search for single-photon events in 53 fb^-1 of e+e- collision data collected with the BaBar detector at the PEP-II B-factory. We look for events with a single high-energy photon…

Search for new -like particles produced in association with a -lepton pair

The BABAR Collaboration, J. P. Lees, others

We report on a search in annihilations for new -like particles produced in association with a -lepton pair. These objects, with a similar mass and similar decay mo…

A Search for the Rare Decays B --> pi l+l- and B0 --> eta l+l-

The BABAR Collaboration, J. P. Lees, others

We present the results of a search for the rare flavor-changing neutral-current decays B --> pi l+l- (pi=pi+/-, pi0 and l = e,mu) and B0 --> eta l+l- using a sample of e+e- --> Y(4…

Search for the rare decays Bs -->mumu and Bd -->mumu

LHCb Collaboration, R. Aaij, B. Adeva +542

A search for the decays Bs-->mumu and Bd-->mumu is performed with about 37 pb^{-1} of pp collisions at sqrt{s} = 7 TeV collected by the LHCb experiment at the Large Hadron Collider…

Simultaneous Extraction of the Fermi constant and PMNS matrix elements in the presence of a fourth generation

Heiko Lacker, Andreas Menzel

Several recent studies performed on constraints of a fourth generation of quarks and leptons suffer from the ad-hoc assumption that 3 x 3 unitarity holds for the first three genera…

CKM Matrix: Status and New Developments

A. Höcker, H. Lacker, S. Laplace +1

An analysis of the CKM matrix parameters within the {\it R}fit approach is presented using updated input values with special emphasis on the recent measurements from BAB…
