Measurement of basic characteristics and gain uniformity of a triple GEM detector / Patra, Rajendra Nath (Calcutta, VECC) ; Singaraju, Rama N. (Calcutta, VECC) ; Biswas, Saikat (CAPSS, Kolkata) ; Ahammed, Zubayer (Calcutta, VECC) ; Nayak, Tapan K. (Calcutta, VECC ; CERN) ; Viyogi, Yogendra P. (Calcutta, VECC)
Large area Gas Electron Multiplier (GEM) detectors have been the preferred choice for tracking devices in major nuclear and particle physics experiments. Uniformity over surface of the detector in terms of gain, energy resolution and efficiency is crucial for the optimum performance of these detectors. [...]

Enhanced production of multi-strange hadrons in high-multiplicity proton–proton collisions / ALICE Collaboration
At sufficiently high temperature and energy density, nuclear matter undergoes a transition to a phase in which quarks and gluons are not confined: the quark–gluon plasma (QGP). Such an exotic state of strongly interacting quantum chromodynamics matter is produced in the laboratory in heavy nuclei high-energy collisions, where an enhanced production of strange hadrons is observed.

Higher harmonic flow coefficients of identified hadrons in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV / ALICE Collaboration
The elliptic, triangular, quadrangular and pentagonal anisotropic flow coefficients for $\pi^{\pm}$, $\mathrm{K}^{\pm}$ and p+$\overline{\mathrm{p}}$ in Pb-Pb collisions at $\sqrt{s_\mathrm{{NN}}} = 2.76$ TeV were measured with the ALICE detector at the Large Hadron Collider. The results were obtained with the Scalar Product method, correlating the identified hadrons with reference particles from a different pseudorapidity region. [...]

J/$\psi$ suppression at forward rapidity in Pb–Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV / ALICE Collaboration
The inclusive J/$\psi$ production has been studied in Pb-Pb and pp interactions at the centre-of-mass energy per nucleon-nucleon collision $\sqrt{s_{\rm NN}} = 5.02$ TeV, using the ALICE detector at the CERN LHC. The J/$\psi$ meson is detected, in the centre-of-mass rapidity interval $2.5<y<4$ and in the transverse momentum range $p_{\rm T}<12$ GeV/$c$, via its decay to a muon pair. [...]

Elliptic flow of electrons from heavy-flavour hadron decays at mid-rapidity in Pb–Pb collisions at $\sqrt{s_{\rm NN}}= 2.76$ TeV / ALICE Collaboration
The elliptic flow of electrons from heavy-flavour hadron decays at mid-rapidity ($|y| < 0.7$) is measured in Pb–Pb collisions at $\sqrt{s_{\rm NN}}= 2.76$ TeV with ALICE at the LHC. The particle azimuthal distribution with respect to the reaction plane can be parametrized with a Fourier expansion, where the second coefficient ($v_2$) represents the elliptic flow. [...]

Measurement of azimuthal correlations of D mesons and charged particles in pp collisions at $\sqrt{s}=7$ TeV and p-Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV / ALICE Collaboration
The azimuthal correlations of D mesons and charged particles were measured with the ALICE detector in pp collisions at $\sqrt{s}=7$ TeV and p-Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV at the Large Hadron Collider. D$^0$, D$^+$, and D$^{*+}$ mesons with transverse momentum $3 < p_{\rm T} < 16$ GeV/$c$ and rapidity in the nucleon-nucleon centre-of-mass system $|y_{\rm cms}| < 0.5$ (pp collisions) and $-0.96 < y_{\rm cms} < 0.04$ (p-Pb collisions) were correlated to charged particles with $p_{\rm T} > 0.3$ GeV/$c$.

D-meson production in $p$–Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV and in $pp$ collisions at $\sqrt{s}=7$ TeV / ALICE Collaboration
The production cross sections of the prompt charmed mesons D$^0$, D$^+$, D$^{*+}$ and D$_{\rm s}^+$ were measured at mid-rapidity in p-Pb collisions at a centre-of-mass energy per nucleon pair $\sqrt{s_{\rm NN}}=5.02$ TeV with the ALICE detector at the LHC. D mesons were reconstruct ed from their decays D$^0\rightarrow {\rm K}^-\pi^+$, D$^+\rightarrow {\rm K}^-\pi^+\pi^+$, D$^{*+}\rightarrow {\rm D}^0\pi^+$, D$_s^+\rightarrow\phi\pi^+\rightarrow {\rm K}^-{\rm K}^+\pi^+$, and their charge conjugates.

We present measurements of the elliptic ($\mathrm{v}_2$), triangular ($\mathrm{v}_3$) and quadrangular ($\mathrm{v}_4$) anisotropic azimuthal flow over a wide range of pseudorapidities ($-3.5< \eta < 5$). The measurements are performed with Pb-Pb collisions at $\sqrt{s_{\text{NN}}} = 2.76$ TeV using the ALICE detector at the Large Hadron Collider (LHC). [...]
