Quantum Chromodynamics (QCD) describes quarks and gluons interactions. Due to asymptotic freedom, a sufficiently high energy density can lead matter to transition into the Quark-Gluon Plasma (QGP), a deconfined form of matter. In heavy-ion collisions, a medium governed by strong interactions is formed, and its evolution can be studied by the produc...
The study of the quark-gluon plasma (QGP), a state of matter which is supposed to have existed after big-bang, is the objective of ultra-relativistic nuclear collisions. At the Large Hadron Collider (LHC), ALICE (A Large Ion Collider Experiment) is designed to produce and investigate the characteristics of QGP, whose presence at high temperature is...
The second-order ($ v_{2} $) and third-order ($ v_{3} $) Fourier coefficients describing the azimuthal anisotropy of prompt and nonprompt (from b-hadron decays) J/$\psi$, as well as prompt $ \psi $(2S) mesons are measured in lead-lead collisions at a center-of-mass energy per nucleon pair of $ \sqrt{\smash[b]{s_{_{\mathrm{NN}}}}} = $ 5.02 TeV. The ...
Identifying the nature of dark matter is a major unsolved problem in physics. The detection of low-energy cosmic-ray antinuclei could provide a $``$smoking gun$"$ signature of dark matter annihilation or decay, as they are produced essentially free of the astrophysical background. Such a detection could also indicate new astrophysical phenomena lik...
In this contribution, the latest results on hadronization studies of charm and beauty quarks obtained with the data collected with the ALICE experiment at the LHC are presented. Measurements of prompt and non-prompt charm-hadron production in pp, p-Pb and Pb-Pb are shown. The results are also compared with theoretical models that consider different...
A study of prompt $\Xi_{c}^{+}$ production in proton-lead collisions is performed with the LHCb experiment at a centre-of-mass energy per nucleon pair of 8.16 TeV in 2016 in $p$Pb and Pb$p$ collisions with an estimated integrated luminosity of approximately 12.5 and 17.4 nb$^{-1}$, respectively. The $\Xi_{c}^{+}$ production cross-section, as well a...
In this paper, we study the greybody factors (GFs) for fermions with different spins and bosons in the regular black hole (BH) predicted by a non-minimal Einstein-Yang-Mills (EYM) theory. We investigate the effect of magnetic charge on effective potentials and GFs. For this purpose, we consider the Dirac and Rarita-Schwinger, as well as Klein-Gordo...

The MALTA family of Depleted Monolithic Active Pixel Sensor (DMAPS) produced in Tower 180 nm CMOS technology targets radiation hard applications for the HL-LHC and beyond. Several process modifications and front-end improvements have resulted in radiation hardness up to 2 × 1015 1 MeV neq/cm2 and time resolution below 2 ns, with uniform charge coll...
Ultra-peripheral collisions (UPC) are events characterised by large impact parameters between the two projectiles, larger than the sum of their radii. In UPCs, the protons and ions accelerated by the LHC do not interact via the strong interaction and can be regarded as sources of quasireal photons. Photoproduction of vector mesons (e.g. J/$\psi$ an...
The first measurement of the cross section for incoherent photonuclear production of J/$\psi$ vector meson as a function of the Mandelstam $|t|$ variable is presented. The measurement was carried out with the ALICE detector at midrapidity, $|y|
