Description

The Super Tau Charm Facility (STCF), a planned symmetric electron-positron collider in China, aims to facilitate $e^+e^−$ collisions across a center-of-mass energy range of 2 to 7 GeV, targeting a peak luminosity of $0.5×10^{35}\mathrm{cm}^{−2}\mathrm{s}^{−1}$. With an anticipated annual integrated luminosity exceeding $1~ab^{−1}$, the STCF is poised to generate vast datasets. These will enable precision measurements of XYZ particles' properties, exploration of new CP violation sources within strange-hyperon and tau-lepton sectors, and accurate Cabibbo angle ($\theta_c$) measurements to test the unitarity of the CKM matrix; search for anomalous decays with sensitivities extending down to the level of SM-model expectations, among other objectives. This talk will cover the STCF's physics goals and outline the latest advancements in the project’s R&D.
