چکیده

We analyse some features of WW scattering processes at LHC. The severe cancellations between fusion diagrams and the other contributions evidence the necessity of complete calculations for studying the high WW invariant mass region and disentangling the standard Higgs case from new physics.

Gauge-Boson Pair Production at the LHC: Anomalous Couplings and Vector-Boson Scattering

We compare vector boson fusion and quark antiquark annihilation production of vector boson pairs at the LHC and include the effects of anomalous couplings. Results are given for confidence intervals for anomalous couplings at the LHC assuming that measurements will be in agreement with the standard model. We consider all couplings of the general triple vector boson vertex and their correlations...

Boson - boson scattering and Higgs production at the LHC from a six fermion

Boson-boson scattering and Higgs production in boson-boson fusion hold the key to electroweak symmetry breaking. In order to analyze these essential features of the Standard Model we have performed a partonic level study of all processes q1q2 → q3q4q5q6lν at the LHC using the exact matrix elements at O(α 6 em) provided by PHASE, a new MC generator. These processes include also three boson produ...

Gauge-boson scattering signals at the LHC

We have extended our earlier treatment of the gauge-boson scattering with radiative corrections in the standard model at supercollider energies, and computed the rates for gauge-boson scattering modes in pp collisions leading to the final states W+W−, ZZ(4l), ZZ(2l2ν), W±Z, and W±W±. Our results at the LHC energy of √ s = 14 TeV for mH = 1000 GeV are compared with those recently obtained by Bag...

Theoretical Aspects of Higgs Physics at the LHC

The strategies recently developed to study Higgs boson properties at the LHC are reviewed. It is shown how to obtain model-independent determinations of couplings to fermions and gauge bosons by exploiting different production and decay channels. We consider the case of Weak Boson Fusion Higgs production with H → bb̄ PACS. 14.80.Bn Standard-Model Higgs boson – 13.85.Hd Inelastic Scattering: many...

Phenomenology of Higgsless Models at the LHC and the ILC

We investigate the signatures of the recently proposed Higgsless models at future colliders. We focus on tests of the mechanism of partial unitarity restoration in the longitudinal vector boson scattering, which do not depend on any Higgsless model-building details. We study the LHC discovery reach for charged massive vector boson resonances and show that all of the preferred parameter space wi...
