Theoretical Challenges for a Precision Measurement of the W Mass at Hadron Colliders

We discuss the O(alpha) electroweak radiative corrections to W and Z boson production and their impact on the measurement of the W mass at hadron colliders. The results of recent improved calculations are presented. We also briefly discuss the O(alpha) corrections to Drell-Yan production in the high invariant mass region.Comment: 12 pages latex, uses aipproc.sty, 6 postscript figures, to appear in the Proceedings of the MRST Conference, Rochester, NY, May 8-9, 200

Measuring the W Boson Mass at Hadron Colliders

We discuss the prospects for measuring the W mass in Run II of the Tevatron and at the LHC. The basic techniques used to measure M_W are described and the statistical, theoretical and detector-related uncertainties are discussed in detail.Comment: Latex, 13 pages, 6 figures, 1 table, invited talk presented at the Mini-Workshop ``Electroweak Precision Data and the Higgs Mass'', DESY Zeuthen, Germany, February 28 - March 1, 2003, to appear in the Proceeding

Measuring Trilinear Gauge Boson Couplings at Hadron and Lepton Colliders

We discuss the measurement of the $WWV$ ($V=\gamma,\, Z$) gauge boson couplings in present and future collider experiments. The major goals of such experiments will be the confirmation of the Standard Model (SM) predictions and the search for signals of new physics. The present limits on these couplings from Tevatron and LEP2 experiments as well as the expectations from future hadron and lepton collider experiments are summarized. We also study the impact of initial state radiation on the sensitivity limits which can be achieved at the NLC and a $\mu^+\mu^-$ collider.Comment: LaTeX, uses aipproc.cls, aipproc.sty, 11 pages, 3 figures, talk given at the Workshop on Physics at the First Muon Collider, Fermilab, November 1997, to appear in the Proceeding

Electroweak Radiative Corrections to Weak Boson Production at Hadron Colliders

We summarize the status of calculations of the electroweak radiative corrections to W and Z boson production via the Drell-Yan mechanism at hadron colliders. To fully exploit the precision physics potential of the high-luminosity environment of the Fermilab Tevatron pbar p (Run II) and the CERN LHC pp colliders, it is crucial that the theoretical predictions are well under control. The envisioned precision physics program includes a precise measurement of the W boson mass and width, and the (leptonic) weak mixing angle, as well as probing the Standard Model (SM) of electroweak interactions at the highest accessible center-of-mass energies. Some numerical results are presented.Comment: Latex, 5 pages, 4 figures, talk given by UB at RADCOR2002/Loops and Legs, Kloster Banz, Germany, Sep. 2002, to appear in the Proceeding

Hadron collider limits on anomalous WWγWW\gamma couplings

A next-to-leading log calculation of the reactions $pp$ and $p\overline{p}\rightarrow W^\pm\gamma X$ is presented including a tri-boson gauge coupling from non-Standard Model contributions. Two approaches are made for comparison. The first approach considers the tri-boson $WW\gamma$ coupling as being uniquely fixed by tree level unitarity at high energies to its Standard Model form and, consequently, suppresses the non-Standard Model contributions with form factors. The second approach is to ignore such considerations and calculate the contributions to non-Standard Model tri-boson gauge couplings without such suppressions. It is found that at Tevatron energies, the two approaches do not differ much in quantitative results, while at Large Hadron Collider (LHC) energies the two approaches give significantly different predictions for production rates. At the Tevatron and LHC, however, the sensitivity limits on the anomalous coupling of $WW\gamma$ are too weak to usefully constrain parameters in effective Lagrangian models.Comment: Revtex 23 pages + 8 figures, UIOWA-94-1
