In this study experiments were performed at bremsstrahlung end-point energies of 10–23 MeV with the beam from the MT-25 microtron (Joint Institute for Nuclear Research, Dubna) using the γ-activation technique. The experimental values of relative yields, cross sections per equivalent quantum and flux-averaged cross sections were compared with theoretical results obtained on the basis of TALYS-2.0 code with the standard parameters and the combined model of photonucleon reactions. Including isospin splitting in the combined model of photonucleon reactions allows describing experimental data on reactions with proton escape in the energy range from 15 to 23 MeV. Therefore, taking into account isospin splitting is necessary for a correct description of the decay of the giant dipole resonance.

The role of continuum coupling to the breakup of the deuteron is clearly shown through microscopic continuum discretized coupled channel (CDCC) calculations carried out with and without this coupling. The analysis was further extended to construct an effective potential (U$_{eff}$) from the sum of cluster folding (CF) and dynamical polarization (DPP) potentials that allow the continuum coupling to be more easily visualized. The considered d + $^{90}$Zr and $^{116}$Sn ADs are reasonably reproduced within the U$_{eff}$ without any additional adjustments over the wide energy range of this study from ~ 23 to 196 MeV. Both methods clearly show the growth in the influence of coupling to the breakup channel as a function of an increase in deuteron energy. The findings of this study provide evidence supporting the use of the U$_{eff}$ to describe elastic angular distribution (AD) data across a wide range of energies.

The present work presents a detailed analysis of angular distribution data for the $^{15}$N + $^{16}$O system in the energy range E$_{c.m.}$ = 10.3–20.6 MeV that are characterized by pronounced increases in cross sections at large angles > 130°. These data sets allow for the energy dependence of elastic scattering potentials and elastic proton transfer to be explored from energies just below the Coulomb barrier to energies about 1.5 times its value. For this purpose, we have implemented various forms, both phenomenological and microscopic, for the interaction potentials. An elastic proton transfer amplitude for the $^{16}$O → p + $^{15}$N configuration was added to the scattering analysis through DWBA calculations. The extracted amplitudes were roughly energy and optical model form independent and yielded a good description of the enhanced large angle cross sections. These amplitudes when then converted to $^{16}$O → p + $^{15}$N spectroscopic factors (SF), are in good agreement with previously reported light ion reaction ones. Possible channel coupling effects on the large angle cross sections that included excitation of $^{16}$O and transfer to excited $^{15}$N states were carried out through Coupled Reaction Channels (CRC) calculations and found to be small.

FASER, the ForwArd Search ExpeRiment, has successfully taken data at the LHC since the start of Run 3 in 2022. With 2022 data alone, FASER directly detected the first muon and electron neutrinos at the LHC, opening the window on the new subfield of collider neutrino physics. In this paper, we will give a full status update of the FASER and FASERnu experiments and their latest results, with a particular focus on our very first measurements of neutrino cross sections in the TeV-energy range, along with its implications for far forward hadron production.

The Compact Muon Solenoid (CMS) experiment will undergo phase-II upgrade to enhance the capacity of detectors in the High-Luminosity Large Hadron Collider era. An important extension involves the installation of the Improved Resistive Plate Chambers (iRPC) in the most forward part of the endcap muon system. The iRPC detector addresses the efficiency drop experienced by the current CMS trigger system for single muon triggers in the high pseudorapidity region. It features a double-ended read-out method, allowing the determination of the hit position along the strip using the time difference between signals from both ends. This feature provides precise spatial information for clustering. To utilize this feature and integrate iRPC cluster information into the CMS trigger system, this paper proposes a 2-Dimensional (2D) cluster-finding algorithm. This algorithm provides the 2D coordinates to CMS trigger system, with each cluster being timestamped to reduce time ambiguity in endcap trajectory reconstruction. The proposed algorithm was implemented in the firmware of the iRPC Back-End Electronics and evaluated using a dedicated cosmic muon setup. The results show a position precision of 2.55 cm and an algorithm efficiency better than 99%, demonstrating the algorithm's potential to improve muon detection and trigger efficiency in the CMS endcap region.
