Two-Loop Formfactors in Theories with Mass Gap and Z-Boson Production
The two-loop formfactor both for a U(1) × U(1) and a SU(2) × U(1) gauge theory with massive and massless gauge bosons respectively is evaluated at arbitrary momentum transfer q2. The asymptotic behaviour for q2 → ∞ is compared to a recent calculation of Sudakov logarithms. The result is an important ingredient for the calculation of radiative corrections to Z-boson production at hadron and lept...
متن کاملFirst observation of electroweak Z boson plus two jet production
Events with jets produced in association with a Z boson in proton-proton collisions can be used to study distributions sensitive to the vector boson fusion (VBF) process at CERN’s Large Hadron Collider. This process is interesting to study because of its similarity to the VBF production of a Higgs boson as well as its sensitivity to new physics via the WWZ triple gauge coupling. Evidence for el...
متن کاملA Z ′ Boson and the Higgs Boson Mass
The Standard Model fit prefers values of the Higgs Boson mass mH that are below the 114 GeV direct lower limit from LEP II. The discrepancy is acute if the 3.2σ disagreement for sinθ` eff W from the two most precise measurements is attributed to underestimated systematic error. In that case the data suggests new physics to raise the predicted value of mH . One of the simplest possibilities is a...
متن کاملStandard Model Higgs boson mass from inflation: two loop analysis
We extend the analysis of [1] of the Standard Model Higgs inflation accounting for two-loop radiative corrections to the effective potential. As was expected, higher loop effects result in some modification of the interval for allowed Higgs masses mmin < mH < mmax, which somewhat exceeds the region in which the Standard Model can be considered as a viable effective field theory all the way up t...
متن کاملZ 3 Dark Matter and Two - Loop Neutrino Mass
Dark matter is usually distinguished from ordinary matter by an odd-even parity, i.e. the discrete symmetry Z 2. The new idea of Z 3 dark matter is proposed with a special application to generating radiative Majorana neutrino masses in two-loop order.
