Description
SuperB experiment could represent an ideal environment to test a new
U(1) symmetry related to light dark forces candidates.
A promising discovery channel is represented by the resonant
production of a boson $U$, followed by its decay into lepton pairs.
Beyond approximations adopted in the literature, an exact tree level
calculation of the radiative processes $e^+ e^- \rightarrow \gamma, U
\rightarrow \mu^+ \mu^- \gamma, e^+ e^- \gamma$ and corresponding QED
backgrounds is performed, including also the most important
higher-order corrections.
The calculation is implemented in a release of the generator
BabaYaga@NLO useful for data analysis and interpretation.
The distinct features of $U$ boson production are shown and the
statistical significance is analysed.
