Exclusive measurements of b → sγ transition rate and photon energy spectrum

J. P. Lees, +370 more
- 26 Sep 2012 - 
TL;DR: In this paper, the authors measured the radiative transition rate of b→sγ with a sum of 38 exclusive final states and found that the inclusive branching fraction with a minimum photon energy of 1.9 GeV is found to be B(B → X_sγ)=(3.29±0.19± 0.48)×10+(-4) where the first uncertainty is statistical and the second is systematic.
Journal ArticleDOI

Search for Low-Mass Dark-Sector Higgs Bosons

J. P. Lees, +379 more
TL;DR: This work presents a search for a dark Higgs boson using 516 fb(-1) of data collected with the BABAR detector and sets 90% confidence level upper limits on the product of the standard model-dark-sector mixing angle and the dark-sector coupling constant.
Journal ArticleDOI

Study of the reaction e^{+}e^{-}->psi(2S)pi^{-}pi^{-} via initial state radiation at BaBar

J. P. Lees, +363 more
- 01 Jan 2012 - 
TL;DR: In this paper, the authors investigated the ψ(2S)π+π− mass distribution from 3.95 to 5.95, and measured the center-of-mass energy dependence of the associated e+e−→ψ( 2S)− cross section.
Journal ArticleDOI

Measurements of the absolute branching fractions of B±→ K±Xcc̄

Bernard Aubert, +633 more
TL;DR: In this article, the authors studied the two-body decays of mesons to a charmonium state and showed that the lower bound of the decays is l3.2 at 90% C.L.
Journal ArticleDOI

Study of e+e-→pp̄ via initial-state radiation at BABAR

J. P. Lees, +346 more
- 10 May 2013 - 
TL;DR: In this article, the authors studied the energy dependence of the cross-section of the p-invariant mass spectrum for the e^+e^-→pp γ with the BABAR detector at the SLAC National Accelerator Laboratory at an energy of 10.6 GeV.
