New Precise Measurement of the Pion Weak Form Factors in the Pi+ -> e+ nu gamma Decay

M. Bychkov, D. Počanić, B. A. VanDevender +29

We have measured the branching ratio over a wide region of phase space, based on a total of 65,460 events acquired using the PIBETA detector. Minimum- fit…

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…
