SUMMARY:Studying the Strong Interaction in W/Z events at the LHC
DESCRIPTION:Pierre-Hugues Beauchemin Tufts University Events with jets in t
 he final state are copiously produced via the strong interaction at the LH
 C. Precise measurements of Standard Model cross sections and parameters as
  well as most of the searches for new physics benefit from a thorough unde
 rstanding of QCD\, particularly in the perturbative regime. These are amon
 g the largest sources of uncertainty on top mass measurements and Higgs cr
 oss section estimates. Robust and precise QCD predictions are therefore cr
 ucial for the success of the overall LHC physics program. Because they are
  relatively background-free\, and because of the wide range of jet kinemat
 ics that they can probe\, events with a vector bosons V (with V = W or Z) 
 produced in association with one or more jets provide an ideal test bench 
 to improve our understanding of the strong interaction. Measurements of th
 e kinematic properties and dynamics of V+jet processes and comparisons to 
 theoretical predictions are therefore playing a key role in the LHC physic
 s program. These are the subject of the present talk.  ** The talk will b
 e in French or English\, depending on the public **
