Measurement of B(J/psi->eta_c gamma) at KEDR
V. V. Anashin, V. M. Aulchenko, E. M. Baldin +80
We present a study of the inclusive photon spectrum from 6.3 million J/psi decays collected with the KEDR detector at the VEPP-4M e+e- collider. We measure the branching fraction o…
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…
Measurement of J/psi to eta_c gamma at KEDR
V. V. Anashin, V. M. Aulchenko, E. M. Baldin +79
We present a study of the inclusive photon spectra from 5.9 million J/psi decays collected with the KEDR detector at the VEPP-4M e+e- collider. We measure the branching fraction of…
Measurement of Γ_{ee}(J/ψ)*Br(J/ψ->e^+e^-) and Γ_{ee}(J/ψ)*Br(J/ψ->μ^+μ^-)
KEDR Collaboration, V. V. Anashin, V. M. Aulchenko +80
The products of the electron width of the J/ψmeson and the branching fraction of its decays to the lepton pairs were measured using data from the KEDR experiment at the VEPP-4M ele…
