“…All information is encoded in the hard p T,j spectrum of the signal plus the Z + jet background. The NLO correction to the backgrounds pp → Z/W + jet are known [18]. We show the leading order as well as the NLO cross sections as a function of the p min T,j cut in fig.…”

Astrophysical bounds severely limit the possibility of observing collider signals of gravity with less than 3 flat extra dimensions. However, small distortions of the compactified space can lift the masses of the lightest graviton excitations, evading astrophysical bounds without affecting collider signals of quantum gravity. Following this procedure we reconsider theories with one large extra dimension. A slight space warping gives a model which is safe in the infrared against astrophysical and observational bounds, and which has the ultraviolet properties of gravity with a single flat extra dimension. We extend collider studies to the case of one extra dimension, pointing out its peculiarities. Finally, for a generic number of extra dimensions, we compare different channels in LHC searches for quantum gravity, introducing an ultraviolet cutoff as an additional parameter besides the Planck mass.

“…Even for as simple a process as Drell-Yan, the leading order (LO) results seriously underestimate the cross sections. This has led to the incorporation of the next-to-leading order (NLO) or next-to-leading log (NLL) [24,25] results in Monte Carlos codes [24] or event generators such as JETRAD [23]. However, no calculations exist for the higher order QCD corrections to cross sections mediated by a generic contact interaction.…”

We consider lepton pair production at a hadron collider in a class of effective theories with the relevant operators being four-fermion contact interaction. Despite the nonrenormalizable nature of the interaction, we explicitly demonstrate that calculating QCD corrections is both possible and meaningful. Calculating the corrections for various differential distributions, we show that these can be substantial and significantly different from those within the SM. Furthermore, the corrections have a very distinctive flavour dependence. And finally, the scale dependence of the cross sections are greatly reduced once the NLO corrections are taken into account.

“…At NLO, this is relatively straightforward to do and both phase-space slicing [33][34][35][36][37][38][39] and subtraction [40][41][42][43][44][45] techniques which solve the problem were worked out long time ago. However, as is clear from the massive amount of literature on the subject [46,47,, analogous techniques at NNLO are considerably more complicated to develop and complete solutions took much longer to emerge.…”

We report on a calculation of the vector current contributions to the electroweak production of top quark pairs in e + e − annihilation at next-to-next-to-leading order in Quantum Chromodynamics.Our setup is fully differential and can be used to calculate any infrared-safe observable. The real emission contributions are handled by a next-to-next-to-leading order generalization of the phasespace slicing method. We demonstrate the power of our technique by considering its application to various inclusive and exclusive observables.
