Leptonic decays of neutral vector mesons followed by e+e- -annihilation with account of radiative corrections
Description
The Breit-Wigner formula for the total cross section of e++e-→V→l++l- process is generalized with account of all radiation corrections (RC) of order α and a finite value of energy resolution ΔE1. The value of RC caused by emission of virtual, soft and Bremsstrahlung photons by final leptons is estimated and it is shown that it depends on the value of maximum angle of noncollinearity reaching the biggest value by ΔΘmax→0.
