We give a report on new developments in the ReneSANCe Monte Carlo event generator and its application to the processes used for luminosity monitoring such as small/large angle Bhabha scattering e+e- -> e+e-, e+e- -> gamma gamma and e+e- -> mu+mu-. One-loop EW and higher order corrections, beam energy spread, polarization, and a number of background processes are taken into account.
Radiative corrections due to initial state radiation in electron-positron annihilation are calculated within the QED structure function approach. Results are shown in the next-to-leading logarithmic approximation up to O(alpha^4L^3) order, where L=ln(s/m^2_e) is the large logarithm. Dependence on factorization scale and scheme choices is analyzed. The results are relevant for future...
Parity-violating electron scattering is a powerful tool for precision tests of the Standard Model, enabling highly accurate measurements of the weak mixing angle. The upcoming MOLLER experiment at the Jefferson Lab will measure the electron's weak charge with 0.1% precision, providing sensitivity to new physics at the O(10) TeV scale. This talk will present recent theoretical work aimed at...
The Circular Electron–Positron Collider (CEPC) enables high-precision electroweak studies at the 𝑍 pole. We present a simulation-based study of the forward–backward charge asymmetry ($A^\mu_{FB}$) in $e^+e^-\to\mu^+\mu^-$ events using the TDR reference detector. After optimized event selection, the signal efficiency reaches about 90% with negligible background contamination. Signal and...
Sphaleron production in the Standard Model at high-energy particle collisions remains experimentally unobserved, with theoretical predictions hindered by its nonperturbative real-time nature. In this work, we investigate a quantum simulation approach to this challenge. Taking the $1+1$D $O(3)$ model as a protocol towards studying dynamics of sphaleron in the electroweak theory, we identify the...
