43. Proposal for the prompt inclusive J/psi production measurement at future Super c-tau factories

While B-factories data of prompt inclusive J/ψ production at √s = 10.6 GeV can be described with NLO NRQCD perturbative calculations, there is a significant discrepancy in the predictions of this model with the exclusive J/ψ cross-sections measured at center-of-mass energies up to 4.6 GeV performed by BESIII. This inconstancy is most likely caused by the failure of perturbative calculations...

44. Parametric simulation of the SCT detector

The progress in development of the parametric simulation of the general particle detector for the Super Char-Tau factory project is presented. The simulation is the part of the Aurora project, which is a software suit for SCTF. The tracker, calorimeter, FARICH and muon systems are parameterised and provide responses to primary generated particles. That information is utilised to reconstruct a...

A sensitivity study for the charged lepton flavor violating process $\tau \to \gamma\mu$ at the Super Tau Charm Facility is performed using a fast simulation. With the expected performance of current detector design and the luminosity of 1ab$^{-1}$ in one year, the upper limit of the branching fraction $\mathcal{B}(\tau \to \gamma\mu)$ could be determined to be $1.6\cdot10^{-8}$. The...

We report a feasibility study of pure leptonic decay $D_s^{+}\to\ell^+\nu_{\ell}$ by using a fast simulation software package at STCF. With an expected luminosity of 1 ab$^{-1}$ collected at STCF at a center-of-mass energy of 4.009 GeV, the statistical sensitivity of the branching fraction is determined to be 0.3%. Combining this result with the c → s quark mixing matrix $|V_{cs}|$ element ...

47. A prototype readout ASIC for the RICH detector

Ring Imaging CHerenkov (RICH) detector is one of the candidates for PID (Particle Identification) at STCF. As for the MPGD (Micro Pattern Gas Detector) detector, the readout electronics must feature high density, low noise, and low power consumption. In this poster, a new prototype readout ASIC for the RICH detector is presented. The chip integrates 32 readout channels and is fabricated in a...

49. Use of Artificial Neural Network for Event Reconstruction in FARICH detector

Focusing Aerogel RICH (FARICH) Detector employs a non-uniform aerogel radiator to measure velocity of charged particles with high precision and identify them in the momentum range of a few GeV/c. PID system based on FARICH with SiPM readout is proposed for the SCTF detector which should provide pi/K separation in the entire momentum region of the experiment and mu/pi separation up to 1.5 GeV/c...
