Transverse momentum spectra and nuclear modification factors of charged particles in Xe-Xe collisions at $\sqrt{s_{\rm NN}}$ = 5.44 TeV

Invariant differential yields of deuterons and antideuterons in pp collisions at s = 0.9, 2.76 and 7 TeV and the yields of tritons, He3 nuclei, and their antinuclei at s = 7 TeV have been measured with the ALICE detector at the CERN Large Hadron Collider. The measurements cover a wide transverse momentum (pT) range in the rapidity interval |y|<0.5, extending both the energy and the pT reach of previous measurements up to 3 GeV/c for A=2 and 6 GeV/c for A=3.

Results on the production of 4 He and He‾4 nuclei in Pb–Pb collisions at sNN=2.76TeV in the rapidity range |y|<1 , using the ALICE detector, are presented in this paper. The rapidity densities corresponding to 0–10% central events are found to be dN/dyHe4=(0.8±0.4(stat)±0.3(syst))×10−6 and dN/dyHe‾4=(1.1±0.4(stat)±0.2(syst))×10−6 , respectively. [...]

First results on the longitudinal asymmetry and its effect on the pseudorapidity distributions in Pb–Pb collisions at sNN = 2.76 TeV at the Large Hadron Collider are obtained with the ALICE detector. The longitudinal asymmetry arises because of an unequal number of participating nucleons from the two colliding nuclei, and is estimated for each event by measuring the energy in the forward neutron-Zero-Degree-Calorimeters (ZNs). [...]

The production of Z0 bosons at large rapidities in Pb–Pb collisions at sNN=5.02TeV is reported. Z0 candidates are reconstructed in the dimuon decay channel ( Z0→μ+μ− ), based on muons selected with pseudo-rapidity −4.0<η<−2.5 and pT>20GeV/c . [...]

Neutral pion and $\eta $ meson invariant differential yields were measured in non-single diffractive p–Pb collisions at $\sqrt{s_{\mathrm{NN}}}$  = 5.02 TeV with the ALICE experiment at the CERN LHC. The analysis combines results from three complementary photon measurements, utilizing the PHOS and EMCal calorimeters and the Photon Conversion Method. [...]

The p$_{T}$-differential production cross section of prompt Λ$_{c}^{+}$ charmed baryons was measured with the ALICE detector at the Large Hadron Collider (LHC) in pp collisions at $ \sqrt{s}=7 $ TeV and in p-Pb collisions at $ \sqrt{s_{\mathrm{NN}}}=5.02 $ TeV at midrapidity. The Λ$_{c}^{+}$ and $ {\overline{\varLambda}}_{\overline{\mathrm{c}}} $ were reconstructed in the hadronic decay modes Λ$_{c}^{+}$ → pK$^{−}$π$^{+}$, Λ$_{c}^{+}$ → pK$_{S}^{0}$ and in the semileptonic channel Λ$_{c}^{+}$ → e$^{+}$ν$_{e}$Λ (and charge conjugates). [...]

The production of the charm-strange baryon Ξc0 is measured for the first time at the LHC via its semileptonic decay into e Ξ−+νe in pp collisions at s=7 TeV with the ALICE detector. The transverse momentum ( pT ) differential cross section multiplied by the branching ratio is presented in the interval 1<pT<8 GeV/c at mid-rapidity, |y|<0.5 . [...]

The ALICE Collaboration reports the measurement of semi-inclusive distributions of charged-particle jets recoiling from a high-transverse momentum trigger hadron in p–Pb collisions at sNN=5.02 TeV. Jets are reconstructed from charged-particle tracks using the anti- kT algorithm with resolution parameter R=0.2 and 0.4. [...]
