We illustrate the effects of one-loop weak corrections onto the production of neutral gauge bosons of the Standard Model at RHIC-Spin, Tevatron and LHC, in presence of quark/gluon radiation from the initial state. We find such effects to be rather large, up to O(10 − 20%) in typical observables at all such colliders, where the cross section is measurable, thus advocating their inclusion in prec...

We calculate next-to-next-to-leading order soft-gluon corrections to top quark total and differential cross sections in hadron colliders. We increase the accuracy of our previous estimates by including additional subleading terms, including next-to-next-to-next-toleading-logarithmic and some virtual terms. We show that the kinematics dependence of the cross section vanishes near threshold and i...

We compute the threshold-resummed cross section for pseudo-scalar MSSM Higgs boson production by gluon fusion at hadron colliders. The calculation is performed at next-to-next-to leading logarithmic accuracy. We present results for both the LHC and Tevatron Run II. We analyze the factorization and renormalization scale dependence of the results, finding that after performing the resummation the...

Inclusive production via gluon fusion will be the most important production channel for Higgs boson discovery at the LHC. I report on a calculation of the inclusive Higgs boson production cross section at pp and p¯ p colliders at next-to-next-to-leading order in QCD.

We present the latest version of micrOMEGAs, a code that calculates the relic density of the lightest supersymmetric particle (LSP) in the minimal supersymmetric standard model (MSSM). All tree-level processes for the annihilation of the LSP are included as well as all possible coannihilation processes with neutralinos, charginos, sleptons, squarks and gluinos. The crosssections extracted from ...

We calculate theO(αs) andO(αWmt /M2 W ) corrections to the production of a single top quark via the weak process qq̄ → tb̄ at the Fermilab Tevatron and the CERN Large Hadron Collider. An accurate calculation of the cross section is necessary in order to extract |Vtb| from experiment.

Predictions for the total, elastic and single diffractive cross sections calculated for the LHC in the framework of the Miettinen-Pumplin model are presented. The total cross section is expected to be 15% smaller than that determined by Donnachie and Landshoff in the model with soft pomeron. The diffractive cross section is almost constant in the Tevatron–LHC energy range.

We present a next-to-leading-order calculation of the production of a Z boson with two jets, one or more of which contains a heavy quark (Q = c, b). We show that the cross section with only one heavy-quark jet is larger than that with two heavyquark jets at both the Fermilab Tevatron and the CERN LHC. These processes are the dominant irreducible backgrounds to a Higgs boson produced in associat...

Understanding the pattern of gluon radiation in tt̄ production and decay processes is important for making an accurate determination of the top mass from the momenta of its decay products. The larger energy of the LHC pp collider boosts the top cross section by a factor of 100 compared to that at the Tevatron, but it also increases the amount of additional gluon radiation. We calculate the cross...

We study the effects of top-Higgs anomalous coupling in the production of a pair of Higgs boson via gluon fusion at the Large Hadron Collider (LHC). The introduction of anomalous ttH coupling can alter the hadronic double Higgs boson cross section and can lead to characteristic changes in certain kinematic distributions. We perform a global analysis based on available LHC data on the Higgs to c...
