Higher-order QCD corrections to vector boson production at hadron colliders
نویسنده
چکیده
We present two recent results on higher-order QCD corrections to the production of vector bosons in hadron collisions. We discuss the resummation of logarithmic-enhanced QCD corrections at small values of qT and the matching procedure to consistently combine resummation with the fixed-order perturbative result at intermediate and large qT . We study the perturbative uncertainty of the results and we compare our prediction with Tevatron data for Z bosons production.

Next-to-leading order QCD corrections to slepton pair production via vector-boson fusion
Slepton pairs can be produced in vector-boson fusion processes at hadron colliders. The next-to-leading order QCD corrections to the electroweak production cross section for pp → l̃+l̃− + 2 jets at order αsα 4 have been calculated and implemented in a NLO parton-level Monte Carlo program. Numerical results are presented for the CERN Large Hadron Collider PACS Nos: 11.10.Gh, 12.60.Jv, 14.80.Ly
متن کاملSUSY–QCD Corrections to Higgs Boson Production at Hadron Colliders
We analyze the next-to-leading order SUSY-QCD corrections to the production of Higgs particles at hadron colliders in supersymmetric extensions of the Standard Model. Besides the standard QCD corrections due to gluon exchange and emission, genuine supersymmetric corrections due to the virtual exchange of squarks and gluinos are present. At both the Tevatron and the LHC, these corrections are fo...
متن کاملNNLO QCD corrections to the Higgs-strahlung processes at hadron colliders
We implement, at next-to-next-to-leading order, the QCD corrections to Standard Model Higgs boson production in association with vector bosons at hadron colliders, qq̄ → HV with V = W,Z. They consist of the two–loop corrections to the Drell–Yan process for the production of off-shell vector bosons, qq̄ → V , and in the case of Z final states, of the additional contribution from heavy-quark loop m...
متن کاملHigher-order Qcd Corrections for Vector Boson Production at Hadron Colliders
The study of vector boson production in hadron collisions, the well know Drell-Yan (DY) process, is nowadays extremely important. Owing to the large production rates and clean experimental signatures of W and Z productions, these processes are standard candles for calibration purposes, they lead to precise determinations of vector boson masses and widths and provide important information on par...
متن کاملElectroweak and QCD corrections to Higgs production via vector-boson fusion at the LHC
The radiative corrections of the strong and electroweak interactions are calculated at next-to-leading order for Higgs-boson production in the weak-boson-fusion channel at hadron colliders. Specifically, the calculation includes all weak-boson fusion and quark– antiquark annihilation diagrams to Higgs-boson production in association with two hard jets, including all corresponding interferences....
