Recent BABAR Results on Two-photon Physics
V. P. Druzhinin
Recent BABAR results on two-photon processes are presented. A high statistics study of the two-photon production of the charmonium states eta_c and eta_c(2S) is performed. The mass…
A geometric solution to the coincidence problem, and the size of the landscape as the origin of hierarchy
Raphael Bousso, Ben Freivogel, Stefan Leichenauer +1
Without assuming necessary conditions for observers such as galaxies or entropy production, we show that the causal patch measure predicts the coincidence of vacuum energy and pres…
Search for Production of Invisible Final States in Single-Photon Decays of Upsilon(1S)
P. del Amo Sanchez
We search for single-photon decays of the Upsilon(1S) resonance, Upsilon->gamma+invisible, where the invisible state is either a particle of definite mass, such as a light Higgs bo…
Search for f_J(2220) in radiative J/psi decays
The BABAR Collaboration, P. del Amo Sanchez
We present a search for f_J(2220) production in radiative J/psi -> gamma f_J(2220) decays using 460 fb-1 of data collected with the BABAR detector at the SLAC PEP-II e+e- collider.…
Search for b-->u transitions in B- --> DK- and B- --> D*K- Decays
The BABAR Collaboration, P. del Amo Sanchez et al.
We report results from an updated study of the suppressed decays B- to D K- and B- to D* K- followed by D to K+pi-, where D(*) indicates a D(*)0 or an anti-D(*)0 meson, and D* deca…
Limits on tau Lepton-Flavor Violating Decays in three charged leptons
BaBar Collaboration, J. P. Lees
A search for the neutrinoless, lepton-flavor violating decay of the tau lepton into three charged leptons has been performed using an integrated luminosity of 468 fb^-1 collected w…
