Precision muon decay measurements and improved constraints on the weak interaction
TWIST Collaboration, A. Hillairet, R. Bayes +28
The TWIST Collaboration has completed its measurement of the three muon decay parameters ρ, δ, and P_μξ. This paper describes our determination of ρ, which governs the shape of the…
Towards Antihydrogen Trapping and Spectroscopy at ALPHA
Eoin Butler, Gorm. B. Andresen, Mohammad. D. Ashkezari +37
Spectroscopy of antihydrogen has the potential to yield high-precision tests of the CPT theorem and shed light on the matter-antimatter imbalance in the Universe. The ALPHA antihyd…
Confinement of antihydrogen for 1000 seconds
ALPHA Collaboration, G. B. Andresen, M. D. Ashkezari +36
Atoms made of a particle and an antiparticle are unstable, usually surviving less than a microsecond. Antihydrogen, made entirely of antiparticles, is believed to be stable, and it…
Centrifugal separation and equilibration dynamics in an electron-antiproton plasma
G. B. Andresen, M. D. Ashkezari, M. Baquero-Ruiz +34
Charges in cold, multiple-species, non-neutral plasmas separate radially by mass, forming centrifugally-separated states. Here, we report the first detailed measurements of such st…
Alpha Antihydrogen Experiment
ALPHA Collaboration, M. C. Fujiwara, G. B. Andresen +37
ALPHA is an experiment at CERN, whose ultimate goal is to perform a precise test of CPT symmetry with trapped antihydrogen atoms. After reviewing the motivations, we discuss our re…
Precise measurement of parity violation in polarized muon decay
TWIST Collaboration, J. F. Bueno, R. Bayes +28
We present a new high precision measurement of parity violation in the weak interaction, using polarized muon decay. The TWIST collaboration has measured , where is…
