The electric dipole moments~(EDM) of fundamental particles inherently violate parity~(P) and time-reversal~(T) symmetries. By virtue the CPT theorem in quantum field theory, latter also implies violation combined charge-conjugation parity~(CP) symmetry. We aim to measure EDM muon using frozen-spin technique within a compact storage trap. This method exploits high effective field, \$E \approx 165\$ MV/m, experienced rest frame with momentum about 23 MeV/c when it passes through solenoidal...
We propose an evolution of the Mu2e experiment, called Mu2e-II, that would leverage advances in detector technology and utilize increased proton intensity provided by Fermilab PIP-II upgrade to improve sensitivity for neutrinoless muon-to-electron conversion one order magnitude beyond providing deepest probe charged lepton flavor violation foreseeable future. Mu2e-II will use as much infrastructure possible, providing, where required, improvements apparatus accommodate beam cope with...
An observation of Charged Lepton Flavor Violation (CLFV) would be unambiguous evidence for physics beyond the Standard Model. The Mu2e and COMET experiments, under construction, are designed to push sensitivity CLFV in mu e conversion process unprecedented levels. Whether is observed or not, there a strong case made further improving sensitivity, examining on additional target materials. Mu2e-II proposed upgrade Mu2e, with at least an order magnitude rate over Mu2e. approach challenges this...
Since the first version of Mu2e TDR released at beginning 2015, Calorimeter system has undergone a long list changes to arrive its final design. These were primarily caused by two reasons: (i) technology choice between proposed solution BaF2 crystals readout with solar blind Avalanche Photodiodes (APDs) and backup option CsI Silicon Photomultipliers (SiPM) been completed (ii) channels numbering, mechanical electronics substantially modified while proceeding engineering towards project. This...
