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 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…
Light response of pure CsI calorimeter crystals painted with wavelength-shifting lacquer
E. Frlez, Ch. Broennimann, B. Krause +6
We have measured scintillation properties of pure CsI crystals used in the shower calorimeter built for a precise determination of the pi+ -> pi0 e+ nu decay rate at the Paul Scher…
New Bounds from Searching for Muonium to Antimuonium Conversion
L. Willmann, P. V. Schmidt, H. P. Wirtz +26
A new upper limit for the probability of spontaneous muonium to antimuonium conversion was established at (90%C.L.) in 0.1~T magnetic f…
