Development of very slow negative muon beam

H. Natori

Negative muon is utilized as a good probe not only in the elementary particle physics, but also in the non-destructive elemental analysis. Developments of slow negative muon beam are on going in J-PARC to make more sophisticated analysis. Beam tuning down to …

Axion Dark Matter Research with IBS/CAPP

Yannis Kyriakos Semertzidis, Jihn E. Kim, SungWoo Youn, Jihoon Choi et autres

The axion, a consequence of the PQ mechanism, has been considered as the most elegant solution to the strong-CP problem and a compelling candidate for cold dark matter. The Center for Axion and Precision Physics Research (CAPP) of the Institute for Basic …

COMET Phase-I technical design report

R. Abramishvili, G. Adamov, R.R. Akhmetshin, A. E. Allin et autres

Abstract The Technical Design for the COMET Phase-I experiment is presented in this paper. COMET is an experiment at J-PARC, Japan, which will search for neutrinoless conversion of muons into electrons in the field of an aluminum nucleus ($\mu$–$e$ conversion, $\mu^{-}N \rightarrow …

High rate tolerant multi-wire proportional chamber and its performance evaluation

N. Teshima, K. Yamamoto, M. Aoki, Y. Seiya et autres

We plan an experiment called DeeMe to search for muon to electron conversion with a sensitivity on the order of $10^{-14}$. In the experiment, a magnetic spectrometer will consist of four HV-switching MWPCs with high rate tolerance and an electromagnet. We present …

An experiment to search for mu-e conversion at J-PARC MLF in Japan, DeeMe experiment

H. Natori

Charged lepton flavor violation (CLFV) is a good probe for new physics beyond the standard model of elementary particle physics. The DeeMe experiment is going to search for one of the CLFV processes, mu-e conversion in a nuclear field, with a sensitivity …
