Using muons from backscattered photons on targets for various studies at the EIC

Most proposals involving the use of muon beams utilize protons on targets to produce pions, which then decay into muons for various studies.  Such muon beams usually require emittance cooling before they are useful.  However, an alternative is to use muon beams produced by backscattered photon beams on suitable targets, thereby obviating the need for muon beam cooling.  Preliminary studies indicate that the EIC’s electron beam of ~20 GeV yields ~5 x 10^13 photons/sec of energy ~5 GeV.  Simulations are currently being performed to understand the kinematics of muons produced from the EIC backscattered photons on various targets.

In this workshop, we will look deeper into muon beams from backscattered photons on various targets and discuss physics implications from their use.  This should be an important extension of the EIC.
