9. The 2H(p,gamma)3He reaction at BBN energies: implications in Cosmology, particle physics and theoretical nuclear physics

Dr Carlo Gustavino (INFN-Roma1)

25/01/2023, 17:00

Short Contribution

The LUNA collaboration has recently completed the measurement of the D(p,γ)3He cross section at Big Bang Nucleosynthesis (BBN) energies with unprecedented precision. The study of this deuterium-burning process provides a precise determination of the universal baryon density Ωb, in excellent agreement with the value derived from CMB. The new data also provide a stringent constrain the possible...

47. Bottomonium physics at Belle II

Alessandro Boschetti (INFN and University of Turin)

25/01/2023, 17:20

Short Contribution

Bottomonium ($b\overline{b}$) spectroscopy offers excellent opportunities for insights on the behavior of QCD in the non-perturbative regime. In order to guide theorists through the difficult task of modeling non-perturbative QCD phenomena, the experimental measurement of masses, widths, and transition rates of $b\overline{b}$ states is crucial. Recent analyses of Belle and Belle II data...

75. The ITS3 upgrade of the ALICE Inner Tracking System

Prof. Paola La Rocca (INFN Catania)

25/01/2023, 17:40

Short Contribution

During the LHC Long Shutdown 3 (LS3) foreseen in 2026-2028, the ALICE collaboration is planning to replace the innermost three layers of the presently installed Inner Tracking System with a novel vertex detector, called ITS3. This further upgrade will improve the efficiency and tracking capabilities of the ALICE detector, especially at low transverse momentum, opening extraordinary...

57. Relativistic fluid dynamics of multiple conserved charges in heavy-ion collisions

Jan Fotakis (University of Frankfurt)

25/01/2023, 18:00

Short Contribution

The strongly interacting matter created in high-energy heavy-ion collisions contains a multitude of conserved quantum charges, like the baryon number, strangeness, and electric charge. These conserved charges lead to coupled charge currents, e.g. a baryon diffusion current, strangeness current and electric charge current. In this talk, we briefly present a novel derivation of second-order...

42. Investigating the possibility of leakage detection in water distribution using cosmic ray neutrons

Davide Pagano (University of Brescia)

25/01/2023, 18:20

Short Contribution

Water distribution systems can experience high levels of leakage, originating from different sources, such as deterioration due to aging of pipes and fittings, material defects, and corrosion [1]. In addition to causing financial losses and supply problems, leakages in treated water distribution also represent a risk for public health. Nowadays, several techniques for leak detection have been...

44. Probing the X17 existence and properties using proton and neutron beams

Michele Viviani (INFN-Pisa)

Short Contribution

Two striking anomalies have been observed recently in the emission of electron-positron pairs in 7Li(p, e+e-)8Be and 3H(p, e+e-)4He reactions [1-2]. These anomalies have been interpreted as the signature of a new particle, a boson with a mass of 17 MeV (hereafter X17 boson), not foreseen in the particle physics standard model. It has been speculated that the X17 boson could be a mediator of a...
