      Orateur: Francesco Giacosa (UJK, Institute of Physics)
      • a) Abstract

        We discuss the status of both conventional and unconventional mesons between 1 and 2 GeV by using hadronic models that describe their masses, strong, and radiative decays. Various conventional quark-antiquark states are considered: some of them, such as the tensor mesons with JPC=2++ and mesons with JPC=3−−, form well established nonets, while other, such as the axial-tensor mesons with JPC=2−−, are poorly known and still need experimental detection. Then, we also present latest results for some non-conventional candidates, such as the case of hybrid mesons with JPC=1−+ that includes the recently discovered resonance η(1855)

        Using large datasets on the charmonium resonances J/ψ, ψ(3686) and ψ(3770) as well as at various other center-of-mass energies between 3.8 and 5.0 GeV, the BESIII experiment has a strong hadron spectroscopy program in both the light-quark and charmonium sectors. During this talk, recent highlights will be presented including studies of gluon-rich radiative J/ψ decays, the observation of a new iso-vector state in weak decays of open-charm mesons and updates on the spectroscopy of charmonium-like XYZ states.

      Orateur: Raffaele Del Grande (Technical University of Munich)
      • a) Abstract

        Understanding the dynamics of hadrons with different quark content is crucial to solve fundamental aspects of QCD as well as for the implications on the structure of dense stellar objects, such as neutron stars.
        The scarce statistics collected in old scattering experiments for reactions involving unstable hadrons, in particular in the strange quark sector, strongly affect the accuracy of the current theoretical interaction models. Additionally, the modeling of dense nuclear matter requires a precise knowledge of three-body forces, for which a direct measurement is still missing.
        In the past several years the use of correlation techniques, applied to particle pairs produced in high-energy collider experiments, have been proven capable of complementing and expanding the knowledge of hadronic interactions, especially in the strangeness sector. The present contribution provides an overview of the milestones reached by the ALICE Collaboration using the femtoscopy technique in pp collisions at √s=13 TeV. The main highlights are the unprecedented precision studies of the interaction of hadrons containing strange quarks, alongside the extension of the analysis methods to the three-body sector, aiming to experimentally probe the three-body interactions.

      Core - corona effect in air showers Grand-amphy (Institut Pascal)

      Grand-amphy (Institut Pascal)

      530 rue Andre Riviere, Orsay (GPS coordinates: 48◦42024.200N2◦10038.100E) Zoom meeting information: https://universite-paris-saclay-fr.zoom.us/j/81981401388?pwd=aFFOLzlPK0x2UjBXWWt5OUticTNLZz09 Meeting ID : 819 8140 1388 Secret code : 263477
      Orateur: Tanguy Pierog (KIT, IKP)
      • a) Abstract

        The deficit of muons in the simulation of extensive air showers is a long-standing problem and the origin of large uncertainties in the reconstruction of the mass of the high energy primary cosmic rays. Hadronic interaction models, re-tuned after early LHC data, have a more consistent description of the muon content among them but still disagree with data. Collective hadronization due to the formation of a quark gluon plasma (QGP) has already been studied as a possible cause for a larger production of muons under extreme conditions (rare, very central nuclear interactions), but without real success. However, in the view of the most recent LHC data, a collective hadronization phase might not only be limited to such extreme conditions. And because of its different ratio of electromagnetic to hadronic energy, a QGP may have the properties to solve the muon puzzle. This hypothesis is demonstrated using a theoretical approach and tested in a proper way by the modification of hadronic model spectra in CONEX to mimic the production of a QGP also in less extreme conditions with a possible large impact on air shower physics

      • a) Abstract

        An electron-ion collider (EIC) is planned to be built in the US at BNL, with start of construction foreseen early 2030. The aim of the EIC is the investigation of the nucleon (spin) structure, saturation effects, hadronisation, and an improved understanding of the hadron mass. Measurements of quarkonium production can contribute to this effort. Predictions of measurements of inclusive, semi-inclusive and exclusive quarkonium production at the EIC will be presented, in parallel with the corresponding measurements at the LHC

      Orateur: Alessio Sarti (Universita' di Roma "La Sapienza")
      • a) Abstract

        Strong interactions play a fundamental role in shaping how ions and protons interact with matter. An interesting kinetic energy range to study such interactions is in between 100 MeV/un and 1000 MeV/u: the nuclear fragmentation cross sections measured in that range have a significant importance in developing the nuclear models needed in particle therapy (PT) and space radio protection (SRP) applications. You can either study the projectiles used for cancer treatment or the protons and ions that are hitting astronauts in their long, outside earth, missions: energies are in a similar range, and the experimental data is in both cases the key to more robust and effective treatments or a better and more affordable shielding! After a quick introduction of PT and SRP landscapes, the talk will review the status of the experimental quests towards more precise cross section measurements in the relevant energy range and their impact in the field.
