7. Effects of atomic electron momentum distribution on resonant dark sector production

Giovanni Grilli di Cortona (Istituto Nazionale di Fisica Nucleare)

21/06/2024, 11:20

Talk

Experiments using positron beams impinging on fixed targets offer unique capabilities for probing new light dark particles feebly coupled to e^+ e^- pairs, that can be resonantly produced from positron annihilation on target atomic electrons. In this talk, I will discuss the impact of correctly accounting for the momentum distribution of the atomic electrons that shifts the center of mass...

43. ATLAS measurements of Drell Yan processes

Fabio Anulli (Istituto Nazionale di Fisica Nucleare)

21/06/2024, 11:50

Talk

ATLAS has used the W and Z boson production processes to perform a range of precision measurements providing important tests of perturbative QCD and information about the parton distribution functions for quarks within the proton. This talk will present recent differential Z+heavy flavour jets results, measurements of the Drell-Yan cross section as a function of transverse momentum based on...

12. Challenges in top mass determination at LHC

Gennaro Corcella (INFN LNF)

21/06/2024, 12:10

Talk

The top quark mass is a fundamental parameter of the Standard Model, playing a crucial role in the electroweak precision tests and in any statement regarding the stability of the Universe. I discuss a recent top mass determination [see JHEP 06 (2023) 019, 2209.00583], based on a leptonic invariant mass, taking particular care about theoretical (Monte Carlo) uncertainties.
