High-energy hadronic collisions generate environments characterized by temperatures above 100 MeV [1,2], about 100,000 times hotter than the center of the Sun. It is therefore currently unclear how light (anti)nuclei with mass number A of a…

This paper presents the measurement of the isolated prompt photon inclusive production cross section in pp and p-Pb collisions by the ALICE Collaboration at the LHC. The measurement is performed in p-Pb collisions at centre-of-mass energies…

The first measurements of dielectron production at midrapidity ($|\eta_{\rm e}|<0.8$) in proton-proton and proton-lead collisions at $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV at the LHC are presented. The dielectron cross section is measured with the…

Levels in 8B have been investigated experimentally using the invariant-mass technique and compared to ab initio calculations. Data sets obtained using E/A=69-MeV 9C and 13O beams on a Be target have been further analyzed to extend the level…

We performed a high-precision study of the $^{215}$ Po $\alpha$-decay using a LaBr$_3$ scintillating detector in a low-background environment. The $^{227}$Ac intrinsic contamination in the LaBr$_3$ crystal undergoes a decay chain, producing…

The azimuthal anisotropy of prompt D$^\pm_\mathrm{s}$ mesons produced in lead-lead (PbPb) collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV is measured using data obtained with the CMS detector. The dataset corresponds to an…

We report a systematic measurement of elliptic flow ($v_{2}$) of $K_{s}^{0}$, $\Lambda$, $\overline{\Lambda}$, $\phi$, $\Xi^{-}$, $\overline{\Xi}^{+}$, and $\Omega^{-}$+$\overline{\Omega}^{+}$ at mid-rapidity ($|y| < 1.0$) for isobar,…

The heavy ion induced nuclear reactions are of interest to nuclear physics community since long time. In this paper, we have reported production cross sections of 196Au, 198Au, 199Tl, 200Tl, 201Tl, which might be direct reaction (DIR)…

The distribution of the pseudorapidity density of primary charged particles (${\rm d}N_{\rm ch}/ {\rm d}\eta$) in $|\eta|<1.5$ is measured in pp collisions at a center-of-mass energy of 13.6 TeV using the ALICE detector. Tracks are…

Measurements of transverse momentum ($p_{\rm T}$) and pseudorapidity ($\eta$) dependent flow vector fluctuations in p$-$Pb collisions at $\sqrt{s_{_{\rm NN}}} = 5.02$ TeV at the CERN Large Hadron Collider are presented. By studying…

In scattering experiments, high-virtuality partons, i.e., quarks and gluons, initiate a series of additional parton emissions to create collimated sprays of particles known as jets. This paper presents a measurement of the Lund jet plane…

Low-energy heavy-ion induced reactions often involve incomplete fusion, but the dependence of ICF on various entrance-channel parameters remains unclear. In this work, we measure channel-by-channel production cross-sections of different…

The angular distribution of the differential cross sections for proton elastic scattering from $^{132}$Sn at 196-210 MeV/nucleon was successfully measured over a momentum transfer range of 0.80 to 2.1 fm$^{-1}$. Using a relativistic impulse…

We report on the two-body invariant-mass spectroscopy of $^{9}$He, populated via the 1$p$1$n$ knockout reaction from the two-neutron halo nucleus $^{11}$Li at $\sim$250 MeV/nucleon. A broad $p$-wave resonant state of $^{9}$He was observed…

Quasi-elastic (QEL) scattering measurements have been performed using the $^{28, 30}$Si projectiles off the $^{90}$Zr target at energies around the Coulomb barrier. Coupled-channels (CC) calculations were carried out in a large parameter…

We report on the first measurement of angular correlations between high-energy pions and slow protons in electron-nucleus ($eA$) scattering, providing a new probe of how a nucleus responds to a fast-moving quark. The experiment employed the…

This document is the closeout report for LDRD 23-050, a type-A LDRD project awarded in FY2022 under the title "A Second EIC Detector: Physics Case and Conceptual Design". The project was motivated by the strong interest within the EIC…

The main goal of the NA61/SHINE strong interaction program is to search for the critical point in the phase diagram of strongly interacting matter and to investigate phenomena related to the onset of deconfinement. In recent years, the…

In this paper we present to what extent recent experimental results obtained for $\pi^{0}$ suppression in O-O collisions at $\sqrt{s_{NN}}$=5.36 TeV fit into the systematics for much heavier systems. The systematics with which the…

$^{133}$Xe is an interesting case for plasma physics to explore nuclear excitation by electron capture, as the process can be studied using statistical properties of $^{133}$Xe. In this work we present results on $^{133}$Xe from the…
