Time resolution of the ALICE Time-Of-Flight detector with the first Run 3 pp collisions at $s = 13.6$ TeV

ALICE Collaboration

Particle identification (PID) is a fundamental aspect of the ALICE detector system, central to its heavy-ion and proton-proton physics programs. Among the different PID strategies,…

A New Evidence of Interplay Between Tetrahedral and Octahedral Symmetries and Symmetry Breaking: Exotic Rotational Bands in $^{152}$ Sm

S. Basak, D. Kumar, T. Bhattacharjee +30

We report on an experimental evidence for a new, second tetrahedral band in $_{62}^{152}$ Sm $_{90}$ . It was populated via fusion evaporation reaction, $^{150}{\rm Nd}(Î±, 2n)…

Medium-induced modification of azimuthal correlations of electrons from heavy-flavor hadron decays with charged particles in Pb-Pb collisions at $s_{NN} = 5.02$ TeV

ALICE Collaboration

The azimuthal-correlation distributions between electrons from the decays of heavy-flavor hadrons and associated charged particles in Pb-Pb collisions at $s_{NN} = 5.02$ …

Measurement of the cross sections of $I^_{c}^{0}$ and $I^_{c}^{+}$ baryons and branching-fraction ratio BR( $I^_{c}^{0} \to I^^{-} e^{+} I^½_{e}$ )/BR( $I^_{c}^{0} \to I^^{-} I ¨ ^{+}$ ) in pp collisions at 13 TeV

ALICE Collaboration

The $p_{T}$ -differential cross sections of prompt charm-strange baryons $I^_{c}^{0}$ and $I^_{c}^{+}$ were measured at midrapidity ( $∣ y ∣ < 0.5$ ) in proton-proton (pp) colli…

Multiplicity dependence of $I^¥$ production at forward rapidity in pp collisions at $s$ = 13 TeV

ALICE Collaboration

The measurement of $I^¥$ (1S), $I^¥$ (2S), and $I^¥$ (3S) yields as a function of the charged-particle multiplicity density, $d N_{ch} / d I^\cdot$ , using the ALICE exp…
