“Bounds on new physics at LHC using effective field theory”

Palestrante: Dr. Alberto Tonero, IFT-UNESP

Dia: 23 de maio, terça-feira, às 17h.

Local: Ed. Principal, Ala 2, sala 335, IFUSP.

Resumo da palestra:

In the case in which no new resonances are directly produced at the Large Hadron Collider (LHC), new physics effects are best studied using effective field theory methods. In this scenario, the contribution of new heavy particles can be parametrized in terms of an effective lagrangian that contains higher-dimensional operators made of Standard Model fields. Largest effects are expected to come from operators with lower dimension. In the Standard Model, the leading operators appears at dimension-six and are suppressed by two powers of the new physics scale. The aim is to study of the effects of these higherdimensional operators on LHC observables. The goal is to set stringent bounds on the coefficients of dimension-6 operators taking into account new experimental measurements from the Run II of LHC and to design optimized shape analysis for the high luminosity LHC phase.
