Precise measurement of the Pi+ -> Pi0 e+nu branching ratio
Dinko Pocanic,E. Frlež,V. A. Baranov,W. Bertl,Ch. Brönnimann,M. Bychkov,J. F. Crawford,M. Daum,N. V. Khomutov,A. S. Korenchenko,S. M. Korenchenko,T. Kozlowski,N. P. Kravchuk,N. A. Kuchinsky,Wenhui Li,R. C. Minehart,D. Mzhavia,Barry Ritchie,Stefan Ritt,A. M. Rozhdestvensky,V. V. Sidorkin,L. C. Smith,I. Supek,Zviad Tsamalaidze,B. A. VanDevender,Yang Wang,H. P. Wirtz,H. P. Wirtz,K.O.H. Ziock +28 more
TL;DR: In this article, the authors used a large acceptance calorimeter and a stopped pion beam to make a precise measurement of the rare branching ratio decay branching ratio and found that the branching ratio decays with the number of observed observations.

Design and test of the CMS pixel readout chip
M. Barbero,M. Barbero,W. Bertl,G. Dietrich,A. Dorokhov,A. Dorokhov,Wolfram Erdmann,K. Gabathuler,St. Heising,Ch. Hörmann,Ch. Hörmann,Roland Horisberger,H.Chr. Kästli,Danek Kotlinski,Beat H. Meier,R. Weber,R. Weber +16 more
TL;DR: The readout chip for the CMS pixel detector must handle an enormous flux of data, while keeping the data loss at a minimum as mentioned in this paper, and full size prototype readout chips bump-bonded to sensors have been tested in a pion beam simulating an LHC-like environment.

TL;DR: The theory of Fermi beta decays is one of themost precise components of the Standard Model (SM) ofelectroweak interactions as discussed by the authors, and is therefore analogous to superallowed FermI (SF) tran-sitions in nuclear beta decay.

TL;DR: The branching ratio for radiative muon capture (RMC), relative to the nonradiative process, is sensitive to {ital g}{sub {ital p}}, the induced pseudoscalar coupling constant of the weak hadronic current.

TL;DR: In this article, a large solid-angle photon pair-spectrometer was constructed to measure RMC at TRIUMF, which consists of a cylindrical photon converter and a large-volume drift chamber to track the e+e− pairs.
