Title: High-energy electrons from the muon decay in orbit: Radiative corrections

Abstract

We determine the Ο(α) correction to the energy spectrum of electrons produced in the decay of muons bound in atoms. We focus on the high-energy end of the spectrum that constitutes a background for the muon-electron conversion and will be precisely measured by the upcoming experiments Mu2e and COMET. As a result, the correction suppresses the background by about 20%.

High energy spectrum of internal positrons from radiative muon capture on nuclei

Journal Article Plestid, Ryan ; Hill, Richard J. - Physical Review. D.

The Mu2e and COMET collaborations will search for nucleus-catalyzed muon conversion to positrons (μ^-→e⁺) as a signal of lepton number violation. A key background for this search is radiative muon capture where either (1) a real photon converts to an e⁺e^- pair “externally” in surrounding material, or (2) a virtual photon mediates the production of an e⁺e^- pair “internally.” If the e⁺ has an energy approaching the signal region then it can serve as an irreducible background. In this work we describe how the near end point internal positron spectrum can be related to the real photon spectrum from the same nucleus,more »« less

Muon to electron conversion: how to find an electron in a muon haystack

Journal Article Kurup, A. - Philosophical Transactions of the Royal Society. A, Mathematical, Physical and Engineering Sciences

The standard model (SM) of particle physics describes how the Universe works at a fundamental level. Even though this theory has proven to be very successful over the past 50 years, we know it is incomplete. Many theories that go beyond the SM predict the occurrence of certain processes that are forbidden by the SM, such as muon to electron conversion. This paper will briefly review the history of muon to electron conversion and focus on the high-precision experiments currently being proposed, COMET (Coherent Muon to Electron Transition) and Mu2e, and a next-generation experiment, PRISM. The PRISM experiment intends tomore »« less

Search for $$\mu^- \rightarrow e^+$$ conversion: what can be learned from the SINDRUM-II positron data on a gold target

Journal Article MacKenzie, M. ; Murat, P. - TBD

In their 2006 paper setting the current limit on \mumemconv\ conversion search on a gold target \cite{sindrum_ii:Bertl2006}, the SINDRUM-II collaboration published, along with the electron momentum distribution, the momentum distribution of reconstructed positrons. Near the positron spectrum endpoint, there is a statistically significant excess of observed events over the expected background. We estimate that in the region 88 MeV/c < p < 95 MeV/c there are 13 events with an expected background of about 1-1.5 event, which has not been discussed by the authors. Those 13 events form a bump with a width consistent with the experimental resolution, making one think of amore »« less

Study of the Mu2e sensitivity to the $$\mu^-\rightarrow e^+$$ conversion process

Thesis/Dissertation Diociaiuti, Eleonora

The Mu2e experiment at Fermilab (Batavia, IL) will search for the coherent neutrinoless conversion of a muon into an electron in the electric field of an aluminum atom. The conversion process results in a monochromatic electron with energy slightly below the muon rest mass (more »« less
