The Mu2e experiment at Fermilab will search for the charged-lepton flavor violating neutrino-less conversion of a negative muon into an electron in the field of an aluminum nucleus. The Mu2e detector is composed of a tracker, an electromagnetic calorimeter and an external active veto for cosmic rays. The calorimeter plays an important role in providing excellent particle identification...
Radiatiave muon capture (RMC) is a key background in searches for charge-changing lepton number violation at Mu2e ($\mu^-\rightarrow e^+$). In particular there are concerns that high energy positrons, whose progenitor is either a real- or virtual-photon, can bleed into the signal region for the charge-changing search.
In this work I show positrons produced from off-shell photons can be...
The SpinQuest (Fermilab E1039) experiment will measure an azimuthal asymmetry in the Drell-Yan production of $\mu+$ $\mu-$ pairs from 120 GeV/c proton interactions with polarized nucleons to extract the Sivers function for $\bar{u}$ and $\bar{d}$. A nonzero asymmetry would be “smoking gun” evidence for orbital angular momentum of the light sea-quarks: predicted to be a major contributor to the...
The SpinQuest (Fermilab-E1039) experiment is designed to identify Drell-Yan production of μ+μ− pairs from 120 GeV/c proton interactions. In the next 10 minutes, I will present the exciting ideas for reusing and repurposing the E1039 spectrometer to detect sub-GeV dark-sector particles: a collection of particles that are not charged under the Standard Model forces, and only couple feebly to the...
