LHC Sensitivity to the Resonance Spectrum of a Minimal Strongly Interacting Electroweak Symmetry Breaking Sector

José Ramón Peláez

Universidad Complutense de Madrid

We present a unified analysis of the two main production processes of vector boson pairs at the LHC, VV-fusion and q-qbar annihilation, in a minimal strongly interacting electroweak symmetry breaking sector. Using a unitarized electroweak chiral Lagrangian formalism and modeling the final V_L V_L strong rescattering effects by a form factor, we describe q-qbar annihilation processes in terms of the two chiral parameters that govern elastic V_L V_L scattering. Depending on the values of these two chiral parameters, the unitarized amplitudes may present resonant enhancements in different angular momentum-custodial isospin channels. Scanning this two parameter space, we generate the general resonance spectrum of a minimal strongly interacting electroweak symmetry breaking sector and determine the regions that can be probed at the LHC.

The almuerzo-seminario is intended to be an informal seminar and an open forum for discussion.
