First Observation of an Attractive Interaction between a Proton and a Cascade Baryon

S. Acharya, D. Adamová, S.P. Adhya, A. Adler et autres

This Letter presents the first experimental observation of the attractive strong interaction between a proton and a multistrange baryon (hyperon) ${\mathrm{\ensuremath{\Xi}}}^{\ensuremath{-}}$. The result is extracted from two-particle correlations of combined $p\text{\ensuremath{-}}{\mathrm{\ensuremath{\Xi}}}^{\ensuremath{-}}\ensuremath{\bigoplus}\overline{p}\text{\ensuremath{-}}{\overline{\mathrm{\ensuremath{\Xi}}}}^{+}$ pairs measured in $p\text{\ensuremath{-}}\mathrm{Pb}$ collisions at $\sqrt{{s}_{\mathrm{NN}}}=5.02\text{ }\text{ }\mathrm{TeV}$ at the …

K S 0 and Λ Production in Pb-Pb Collisions at s N N = 2.76 TeV

B. Abelev, J. Adam, D. Adamová, A. Adare et autres

The ALICE measurement of ${K}_{S}^{0}$ and $\ensuremath{\Lambda}$ production at midrapidity in Pb-Pb collisions at $\sqrt{{s}_{NN}}=2.76\text{ }\text{ }\mathrm{TeV}$ is presented. The transverse momentum (${p}_{T}$) spectra are shown for several collision centrality intervals and in the ${p}_{T}$ range from $0.4\text{ }\text{ }\mathrm{GeV}/c$ ($0.6\text{ }\text{ …

Charmonium and e + e − pair photoproduction at mid-rapidity in ultra-peripheral Pb–Pb collisions at $\sqrt{s_{\mathrm{NN}}} = 2.76\ \mbox{TeV}$

E. Abbas, B. I. Abelev, J. Adam, D. Adamová et autres

The ALICE Collaboration at the LHC has measured the J/ψ and ψ′ photoproduction at mid-rapidity in ultra-peripheral Pb–Pb collisions at $\sqrt{s_{\mathrm{NN}}}=2.76~\mathrm{TeV}$ .The charmonium is identified via its leptonic decay for events where the hadronic activity is required to be minimal. The analysis …

In this paper measurements are presented of ${\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}}$, ${K}^{\ifmmode\pm\else\textpm\fi{}}$, $p$, and $\overline{p}$ production at midrapidity ($|y|<0.5$), in Pb-Pb collisions at $\sqrt{{s}_{NN}}=2.76$ TeV as a function of centrality. The measurement covers the transverse-momentum (${p}_{T}$) range from 100, 200, and 300 MeV/$c$ up to …

We present the first wide-range measurement of the charged-particle pseudorapidity density distribution, for different centralities (the 0–5%, 5–10%, 10–20%, and 20–30% most central events) in Pb–Pb collisions at sNN=2.76TeV at the LHC. The measurement is performed using the full coverage of the …
