Abstract

Charge-parity (C ⁣PC\!P) violation in the tau-charm energy region is a promising area for sensitive tests of Standard Model (SM) predictions and searches for new, beyond the SM physics. A future Tau-Charm Facility that operates at center-of-mass energies between 2.0 and 7.0 GeV, with a peak luminosity of 0.5×10350.5\times10^{35}~cm2^{-2}s1^{-1}, would provide huge numbers of hadrons and tau (τ\tau) leptons that are produced in low-background environments and with well understood kinematic properties. In this report, prospects for unique studies of C ⁣PC\!P violation in the decay of charmed hadrons, and in the production and decay of hyperons and τ\tau leptons at a next-generation tau-charm facility are discussed. In addition, opportunities for improved tests of CPTCPT invariance test in K0Kˉ0K^{0}-\bar{K}^{0} mixing are presented.
