162. The muon g-2: status from a theorist's point of view

Prof. Massimo Passera (INFN)

19/10/2016, 11:00

Fundamental physics and precision experiments with muons, pions, neutrons, antiprotons, and other particles

Oral

I will present recent developments in the Standard Model prediction of the muon g-2 and the long-standing discrepancy with its measured value

199. Prospects of Intensity and Precision Frontier

Prof. Naohito SAITO (J-PARC / KEK)

19/10/2016, 11:30

Fundamental physics and precision experiments with muons, pions, neutrons, antiprotons, and other particles

Oral

While we have been longing for the signals of new physics beyond the standard model, there is no convincing indication yet at the high energy frontier, LHC. There is an increasing importance in exploring intensity and precision frontier especially to shape a possible new physics by further investigating the flavor dynamics and by testing symmetries in the nature. In this talk, we try to cover...

214. New insights into the proton radius puzzle and nuclear structure from muonic deuterium

Mr Julian J. Krauth (MPQ Garching)

19/10/2016, 12:00

Low energy precision tests of the Standard Model

Oral

In 2010 the CREMA collaboration measured the rms charge radius of the proton via laser spectroscopy of the 2S-2P Lamb shift in muonic hydrogen [1, 2]. Very recently the charge radius of the deuteron was determined [3]. Both measurements yield very precise charge radii but both values result 7 standard deviations away from the expected values, given by CODATA [4]. Follow-up measurements of the...

221. Commissioning of new DC muon beam line, MuSIC-RCNP at Osaka University

Dr Dai Tomono (Osaka University)

19/10/2016, 12:20

Fundamental physics and precision experiments with muons, pions, neutrons, antiprotons, and other particles

Oral

We have constructed a new DC muon beamline, MuSIC (MUon Science Innovative muon beam Channel) at Research Center for Nuclear Physics (RCNP), Osaka University. The MuSIC comprises the world’s most efficient DC muon source using the first pion capture solenoid system and muon beam transport magnets from the solenoid end to an experimental port. We are now commissioning the beamline and...

152. NLO prediction for μ → eννγ and μ → eeeνν decays in the SM

Dr Matteo Fael (Bern Universität)

19/10/2016, 12:40

Oral

We present the differential decay rates and the branching ratios of the μ → eννγ and μ → eeeνν decays in the SM at next-to-leading order. These two rare decay modes of the muon are among the source of background in the experiments searching for charge lepton flavour violating (CLFV) decays μ → eγ and μ → eee. Indeed, the SM decays are indistinguishable from the CLFV ones except for the energy...
