Probing the Green-Schwarz Mechanism at the Large Hadron Collider
We investigate the phenomenology of new abelian gauge bosons, which we denote as X bosons, that suffer a mixed anomaly with the Standard Model, but are made selfconsistent by the Green-Schwarz mechanism. A distinguishing aspect of the resulting effective theory is the decay of X bosons into Standard Model gauge bosons, X → ZZ,WW, γZ. We compute the production cross-section of the X boson from v...
متن کاملSupersymmetric Higgs production at the Large Hadron Collider
We review the status of theoretical predictions for the production of neutral Higgs bosons at the LHC. Special emphasis is put on the role of bottom quarks in the gluon fusion process and in the associated production of Higgs bosons with bb̄ pairs. PACS. 14.80.Cp Non-standard-model Higgs bosons – 12.38.Bx Perturbative calculations
متن کاملProbing Intermediate Mass Higgs Interactions at the CERN Large Hadron Collider
We analyze the potentiality of the CERN Large Hadron Collider to probe the Higgs boson couplings to the electroweak gauge bosons. We parametrize the possible deviations of these couplings due to new physics in a model independent way, using the most general dimension–six effective lagrangian where the SU(2)L ⊗ U(1)Y is realized linearly. For intermediate Higgs masses, the decay channel into two...
متن کاملSpin Determination at the Large Hadron Collider
The quantum field theory describing the Electroweak sector demands some new physics at the TeV scale in order to unitarize the scattering of longitudinal W bosons. If this new physics takes the form of a scalar Higgs boson then it is hard to understand the huge hierarchy of scales between the Electroweak scale ∼ TeV and the Planck scale ∼ 10 GeV. This is known as the Naturalness problem. Normal...
متن کاملBlack holes at the Large Hadron Collider.
If the scale of quantum gravity is near TeV, the CERN Large Hadron Collider will be producing one black hole (BH) about every second. The decays of the BHs into the final states with prompt, hard photons, electrons, or muons provide a clean signature with low background. The correlation between the BH mass and its temperature, deduced from the energy spectrum of the decay products, can test Haw...
