Monte Carlo programs for small-angle Bhabha scattering
The article titled “Monte Carlo programs for small-angle Bhabha scattering” was published in Chinese Physics C by a team of authors from the JINR Laboratory of Nuclear Problems, the JINR Laboratory of Theoretical Physics and Dubna State University. Among the authors are staff members from the Department of Colliding Beams of our laboratory I. R. Boyko, L. V. Kalinovskaya, A. A. Kanpf, R. R. Sadykov, and V. L. Yermolchik.
Luminosity monitoring at $e^+$$e^–$ colliders was investigated using SANC Monte Carlo event generator ReneSANCe and integrator MCSANC for simulation of Bhabha scattering at low angles. Results are presented for center-of-mass energies of the Z boson resonance and at 240 GeV for the conditions of typical luminosity detectors. It is shown that bremsstrahlung events with extremely low electron scattering angles are relevant to match the precision tags of future electron-positron colliders.
