Low regularity solutions to a gently stochastic nonlinear wave equation in nonequilibrium statistical mechanics

Luc Rey-Bellet, Lawrence E. Thomas

We consider a system of stochastic partial differential equations modeling heat conduction in a non-linear medium. We show global existence of solutions for the system in Sobolev s…

Particle-number scaling of the phase sensitivity in realistic Bayesian twin-mode Heisenberg-limited interferometry

Raphael Pooser, Olivier Pfister

We investigate the scaling of the phase sensitivity of a nonideal Heisenberg-limited interferometer with the particle number N, in the case of the Bayesian detection procedure prop…

Absolute Branching Ratio Normalization for Rare pi+ and mu+ Decays in the PIBETA Experiment

E. Frlez

We have used the PIBETA detector at the PSI for a precise measurement of rare pion and muon weak decays. We have collected a large statistical sample of (1) pi+ -> e+ nu, (2) pi+ -…

Precise Measurement of the Pion Axial Form Factor in the Pi+ -> e+ nu gamma Decay

E. Frlez, D. Pocanic, V. A. Baranov +23

We have studied radiative pion decays Pi+ -> e+ nu gamma in three broad kinematic regions using the PIBETA detector and a stopped pion beam. Based on Dalitz distributions of 42,209…

Design, Commissioning and Performance of the PIBETA Detector at PSI

E. Frlez, D. Pocanic, K. A. Assamagan +41

We describe the design, construction and performance of the PIBETA detector built for the precise measurement of the branching ratio of pion beta decay, pi+ -> pi0 e+ nu, at the Pa…

Observation of Parity Nonconservation in Moller Scattering

the SLAC E158 Collaboration, P. L. Anthony

We report a measurement of the parity-violating asymmetry in fixed target electron-electron (Moller) scattering: A_PV = -175 +/- 30 (stat.) +/- 20 (syst.) parts per billion. This f…
