Resummation of boson-jet correlation at hadron colliders
Abstract
We perform a precise calculation of the transverse momentum (q→T) distribution of the boson+jet system in boson production events. The boson can be either a photon, W, Z or Higgs boson with mass mV, and q→T is the sum of the transverse momenta of the boson and the leading jet with magnitude qT = |q→T|. Using renormalization group techniques and soft-collinear effective theory, we resum logarithms log (Q/qT) and log R at next-to- leading logarithmic accuracy including the non-global logarithms, where Q and R are respectively the hard scattering energy and the radius of the jet. Specifically, we investigate two scenarios of pTJ ≲ mV or pTJ ≳ mV in Z +jet events, and we examine the qT distributions with different jet radii and study the effect of non-global logarithms. In the end we compare our theoretical calculations with Monte Carlo simulations and data from the LHC.
