Project Description:

The Drell-Yan process is an important tool in understanding the
dynamics of quarks and gluons in the proton. The process is q + qbar
--> Z --> e+e- or mu+mu- , and there is the W+ and W- mediated charged
current process too with the W decaying to a charged lepton and
neutrino. Both of these processes help to disentangle the quark
flavour content of the proton and is essential input for all
predctions of other processes at the LHC. At large invariant mass of
the leptons a new kinematic regime is available where theoretical
uncertainties are large and these measurements will help to constrain
the theory. In addition this highly off-shell region is sensitive to
new physics through propagator modifications in effective field
theories. Therefore a precision measurement of the Drell-Yan cross
section slope with invariant mass provides a new search for phyiscs
beyond the Standard Model.
