Precise Measurement of pi+ -> e+ nu Branching Ratio
E. Frlež, L. P. Alonzi, V. A. Baranov +23
The PEN Collaboration is conducting a new measurement of the pi+ -> e+ nu branching ratio at the Paul Scherrer Institute, with the goal uncertainty of delta B/B(pie2)=5E-4 or lower…
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…
Precise Measurement of the Pi+ -> Pi0 e+ nu Branching Ratio
D. Pocanic, E. Frlez, V. A. Baranov +25
Using a large acceptance calorimeter and a stopped pion beam we have made a precise measurement of the rare Pi+ -> Pi0 e+ Nu,(pi_beta) decay branching ratio. We have evaluated the…
