Search for anomalous production of highly boosted Z bosons decaying to mu(+)mu(-) in proton-proton collisions at root s=7 TeV
Original language description
Results are reported from a search for the anomalous production of highly boosted Z bosons with large transverse momentum and decaying to mu(+)mu(-). Such Z bosons may be produced in the decays of new heavy particles. The search uses pp collision data atroot s = 7 TeV, corresponding to an integrated luminosity of 5.0 fb(-1) recorded with the CMS detector. The shape of the observed transverse momentum distribution of Z bosons is consistent with standard model expectations. Constraints are obtained on models predicting the production of excited quarks decaying via electroweak processes. Assuming a compositeness scale that is equal to the excited quark mass as well as transition coupling strengths between Z bosons and excited quarks that are equal to standard model couplings to quarks, masses of excited quarks below 1.94 TeV are excluded at the 95% confidence level. For excited quark production via a novel contact interaction, masses below 2.22 TeV are excluded, even if the excited quark
