Experimental data on the interaction between vector mesons and nucleons are a crucial input for understanding the pattern of in-medium chiral symmetry restoration (CSR) and dynamically generated excited nucleon states. However, accessing these interactions is hampered by the short lived nature of the vector mesons, making traditional scattering experiments unfeasible. In recent years the ALICE...
Motivated by the expected improvement in the experimental determination of the μH Lamb shift measurement, I will present an updated fit of the unpolarised nucleon structure functions from available data in the nucleon resonance region in combination with Regge fits to the high-energy and deep inelastic region. The evaluation of the structure functions in the resonance region is building upon...
Atomic masses are indispensable in nuclear structure and astrophysics research, and Penning-traps enable to determine atomic masses with exceptional precision and accuracy [1]. TRIGA-Trap is a high-precision, double Penning-trap mass spectrometer located in the reactor hall of the TRIGA research reactor in Mainz, Germany, where mass measurements of heavy radioactive nuclides -- particularly...
The QUARTET collaboration aims for high-precision spectroscopy of muonic atoms at the Paul Scherrer Institute (PSI) to extract nuclear charge radii in simple atomic systems. A key motivation of the experiment is to reduce the relative uncertainties of nuclear charge radii for stable isotopes ranging from Lithium to Neon. The current uncertainties in this region suffer mainly from experimental...
The Tile Calorimeter (TileCal) is a crucial component of the ATLAS detector at the Large Hadron Collider (LHC), responsible for measuring the energy of strongly interacting particles (hadrons) produced in proton–proton collisions. Accurate simulation of its performance is essential for physics analyses relying on precise jet and missing transverse energy measurements. To validate the new...
A systematic study of Yb isotopes of even-even nuclei with neutron number N =60-130 has been done with axially deformed covariant density functional theory (CDFT) [1] using finite-range interaction DD-ME2 [2] and zero-range interaction DD-PC1 [3]. The shape coexistence and transitional nature of nuclei are found in the neighbourhood of magic nuclei through the potential energy curve. The...
Manganese isotopes have recently found increasing potential applications in various fields, including nuclear medicine. In the present work, the excitation functions for some manganese isotopes have been measured from deuteron-induced nuclear reactions on natural nickel metals from 24 MeV energy down to threshold using the well-established stacked-foil activation procedure. The activation...
This work presents an analysis of the scaling properties of total and elastic cross sections in proton–proton and neutron–proton collisions from ISR to LHC and cosmic-ray energies. Using the gray disk model, we introduce two energy-dependent functions, R(s) and f(s), that describe the evolution of the effective interaction radius and the gluon saturation density, respectively. The...
