High precision calculations of the properties of nucleons using lattice QCD Rajan Gupta (Los Alamos National Laboratory) Simulations of lattice Quantum Chromodynamics (QCD) are providing increasingly precise predictions of QCD with growing computing power and novel algorithms that have addressed issues of critical slowing down. This talk will cover the calculations being done by the …

Charge Radius of 54Ni and Slope Parameter in the Nuclear Equation of State Skyy Pineda (Post-doctorant MBPE) « The charge radius of the 54Ni nucleus was determined using collinear laser spectroscopy at the BEam COoler and LAser spectroscopy (BECOLA) facility [1,2] at the National Superconducting Cyclotron Laboratory at Michigan State University. The 54Ni charge radius, together …

Experimental validation of a the Gaseous Proton Recoil Telescope for quasi-absolute neutron flux measurements for fission cross section Carole Chatel (IJCLab) The improvement of neutronics simulations makes their accuracy more sensitive to the precision of the input data, such as neutron-induced cross sections. Among the most important ones, fertile actinides fission cross sections play a …

Sonder la taille du neutrino : un voyage au cœur de la mécanique quantique Leendert Hayen L’un des principaux fondements de la mécanique quantique est la dualité onde-particule, l’enchevêtrement des états et leur décohérence à la suite de l’interaction avec leur environnement. Cela s’applique également aux désintégrations radioactives, mais une compréhension détaillée des paquets d’ondes …

Nuclear-structure studies in the upper sd shell using fast rare-isotope beams Tobias Beck The neutron-deficient calcium isotopes, forming the northern boundary of the sd shell, have attracted considerable attention recently. Present studies are divided over the amount of proton pf-shell occupancy, ranging from an intact Z=20 shell closure to a considerable weakening already in the …

R&D à GANIL/SPIRAL1 : vers la production de 100Sn Vincent Bosquet (Post-doctorant MPBE) SPIRAL1 est une installation ISOL qui produit des faisceaux d’ions radioactifs depuis 25 ans, en utilisant la fragmentation comme principal mécanisme de production. Cependant, cette méthode limite la production aux noyaux proches de la vallée de stabilité. Pour surmonter cette limitation, un …

Exploring the tau neutrino appearance oscillation channel in KM3NeT/ORCA Chiara Lastoria Over the past decades, neutrino physics has emerged as a dynamic and fascinating field in particle physics. The experimental observation of the oscillation mechanism, possible if neutrinos have non-zero mass, represented evidence of physics beyond the Standard Model. Nonetheless, several properties of these mysterious …

Modelling Newtonian noise of vibroacoustic origin in the Virgo gravitational wave detector François Gautier LAUM (Laboratoire d’Acoustique de l’université du Mans) Among the noises affecting GW detectors, the « Newtonian » or « gravity-gradient » noise (seismic and atmospheric/acoustic) could limit the low-frequency sensitivity (below a few tens of Hz) of LIGO and Virgo as they reach their full …

Probing exotic cross-shell interactions at N = 28 with single-neutron transfer on 47K Charlie Paxman (Post-doctorant au GANIL) Shell evolution in nuclei far from stability is understood to arise from the complex interplay of orbital interactions, with different interactions accessible in unstable nuclei compared to those near stability. Experimental studies of these exotic regions provide …
