QCD

In these lecture notes I describe the theory of QCD and its application, through perturbation theory, at particle colliders.Comment: 58 pages, contribution to the Proceedings of the 2014 European School of High-Energy Physics. Garderen, the Netherlands, 18 June - 1 July 201

Top quark in theory

I review how the top quark is embedded in the Standard Model and some its proposed extensions, and how it manifests itself in various hadron collider signals.Comment: 12 page

Radiative corrections to eγe \gamma scattering

We investigate the effects of photon radiation on deep-inelastic \re\gamma scattering. Depending on the set of variables chosen, we find appreciable effects in the kinematic region accessible at LEP2. Convenient analytic results for $O(\alpha)$ corrected differential cross sections are presented.Comment: 9 pages, latex + 1 postscript figure, all uuencode

Charm Production in Deep-Inelastic eγe\gamma Scattering To Next-To-Leading Order in QCD

We discuss the calculation of $F_2^{\gamma}({\rm charm})$ to next-to-leading order (NLO) in QCD, including contributions from both hadronlike and pointlike photons. We show that the former dominates strongly below $x\simeq 0.01$, and the latter above this value. This fact makes $F_2^{\gamma}({\rm charm})$ for $x \geq 0.01$ calculable, whereas for $x \leq 0.01$ it serves to constrain the small-$x$ gluon density in the photon. Both ranges in $x$ are accessible at LEP2. Theoretical uncertainties are well under control. We present rates for single-tag events for the process for $e^+e^- \rightarrow e^+e^- c X$ for LEP2. Although these event rates are small, we believe a measurement of $F_2^{\gamma}({\rm charm})$ is feasible.Comment: 7 pages Latex, with 2 eps figs., uuencode

Model-independent QED corrections to photon structure-function measurements

We present the first calculation of QED radiative corrections to deep-inelastic electron-photon scattering in terms of those variables that are reconstructed in measurements of the photon structure function in electron-positron collisions. In order to cover the low-$Q^2$ region, we do not invoke the QCD-improved parton model but rather express our results in terms of the photon structure functions. Both analytical and numerical results are given.Comment: Latex, 8 pages, 3 figures, uses epsfig.sty, 12pt.st

Electroweak-boson hadroproduction at large transverse momentum: factorization, resummation, and NNLO corrections

We study the resummation of singular distributions for electroweak-boson production at large transverse momentum in hadronic collisions. We describe the factorization properties of the cross section near partonic threshold and construct the resummed cross section at next-to-leading logarithmic accuracy in moment space in terms of soft gluon anomalous dimensions. We present full analytical results for the expansion of the resummed cross section up to next-to-next-to-leading order. Our results can be applied to W, Z, and virtual gamma production at hadron colliders.Comment: 15 pages LaTeX, 2 postscript figure
