Description
Contrarily to most of the previous colliders, the initial state at the LHC is charge
asymmetric. This property has been measured on the W process by the ATLAS and the CMS
collaborations using their 2010 datasets.
We propose a new method to use the global charge asymmetry of a production process
to constrain the mass of its final state.
We'll illustrate this method using particle level MC samples run through a fast
simulation of an LHC detector on the W->l+nu process. In particular, we'll propagate
separately the theoretical and the experimental uncertainties in order to estimate
the mass resolution of our method.
The application of this new method can be interesting to obtain further constraints
in some BSM searches as we'll briefly illsutrate.
