The legacy of HL-LHC for the Standard Model EFT @ on-line
May 19 @ 11:00 am – 12:00 pm

Seminario di Fenomenologia – Dr. Riccardo Torre (INFN Sezione di Genova)

The LHC and HL-LHC physics program is not even half-way and the absence of new physics signals claims for a strategy to build what will be the HL-LHC legacy in terms of new physics searches. The lack of signals of light new physics have put the model independent Effective Field Theory (EFT) approach forefront in looking for deviations of observables from their Standard Model predictions. There are mainly three directions in which the EFT program is meeting precision and is expanding its potentials: on-shell Higgs measurements, low energy observables (flavor), and high energy precision. These three are generally described by different sectors of the Standard Model EFT (SMEFT): schematically, Higgs on-shell observables correspond to Higher Dimensional Operators (HDO) involving additional Higgs fields, flavor observables to SMEFT operators at scales well below the EW gauge boson masses (both flavor violating and flavor conserving), while high energy observables correspond to similar operators at scales much above the EW gauge boson masses. Obviously, exploiting the interplay of the three, and combining their information, becomes crucial in building an overall picture.
In this talk I will introduce the three directions highlighted above and then focus on the third: high energy precision. I will introduce the concept of BSM measurements (to be contrasted with SM measurements and BSM searches) and try to motivate why, in my view, this will be the crucial step needed to build what could become the HL-LHC legacy.

Semiclassical gravity and evaporation of dynamical black holes sourced by the quantum trace anomaly @ online
May 26 @ 11:00 am – 12:00 pm

Seminario di Fisica Teorica – Paolo Meda (Università di Genova e INFN di Genova)

A first approximation to describe the interplay between quantum matter and gravity is given by the quantum field on curved spacetimes and the semiclassical gravity, in which the backreaction of a quantum matter field propagating over a fixed spacetime geometry can be analyzed by using the so-called semiclassical Einstein equation. In this framework, the evaporation of four-dimensional spherically symmetric black holes can be explained by the appearance of an ingoing negative energy flux at the apparent horizon, which induces a negative variation of the black hole mass. I will show that this flux can be sourced by the trace anomaly of the quantum stress-energy tensor in case of a massless conformally-coupled scalar field once a certain averaged energy condition is assumed outside the horizon. As an example, I will compute the negative flux and the rate of evaporation in the Vaidya spacetime, which describes the exterior geometry of a null radiating star.

Gli esperimenti WA82 e WA92: un’eredità di silicio @ online
Jun 9 @ 11:00 am – 12:00 pm

Seminario Colloquium (D.Barberis, G.Darbo, C.Gemme, L.Rossi – INFN Sezione di Genova)

La sezione di Genova dell’INFN ha un ruolo leader in Italia, oramai da due decenni, nello sviluppo, nella realizzazione e nell’utilizzo dei rivelatori a Pixel di silicio. Questa attivita’ ha le sue radici negli esperimenti WA82 e WA92 fatti al SPS del CERN nel periodo 1985-1995. Il seminario descrive questi esperimenti, le tecniche utilizzate e i risultati raggiunti e si sofferma infine sui motivi che hanno consentito a Genova di diventare un laboratorio di riferimento per i rivelatori a pixel.
