Inform.) ; Adolfsson, Jonatan (Lund U.) ; Aglieri Rinella, Gianluca (CERN) ; Agnello, Michelangelo (Turin Polytechnic) ; Agrawal, Neelima (INFN, Bologna) ; Ahammed, Zubayer (Calcutta, VECC) ; Ahmad, Shakeel (Aligarh Muslim U.) ; Ahn, Sang Un (KISTI, Daejeon) et al. /ALICE
At particle collider experiments, elementary particle interactions with large momentum transfer produce quarks and gluons (known as partons) whose evolution is governed by the strong force, as described by the theory of quantum chromodynamics (QCD) [1]. The vacuum is not transparent to the partons and induces gluon radiation and quark pair production in a process that can be described as a parton shower [2]. [...]

Charm-quark fragmentation fractions and production cross section at 4 midrapidity in pp collisions at the LHC / Acharya, Shreyasi (Calcutta, VECC) ; Adamova, Dagmar (Rez, Nucl. Phys. Inst.) ; Adler, Alexander (Goethe U., Frankfurt, Inst. Inform.) ; Adolfsson, Jonatan (Lund U.) ; Aglieri Rinella, Gianluca (CERN) ; Agnello, Michelangelo (Turin Polytechnic) ; Agrawal, Neelima (INFN, Bologna) ; Ahammed, Zubayer (Calcutta, VECC) ; Ahmad, Shakeel (Aligarh Muslim U.) ; Ahn, Sang Un (KISTI, Daejeon) et al.
Recent $p_{\rm T}$-integrated cross section measurements of the ground-state charm mesons and baryons, $\mathrm{D^0}$, $\mathrm{D^+}$, $\mathrm{D_s^+}$, $\Lambda_\mathrm{c}^+$, and $\Xi_\mathrm{c}^0$, are used to evaluate the charm fragmentation fractions and production cross section per unit of rapidity at midrapidity ($|y|<0.5$), in pp collisions at $\sqrt{s} = 5.02$ TeV at the LHC. The latter is $\mathrm{d}\sigma^{\mathrm{c\overline{c}}}/\mathrm{d} y|_{|y| < 0.5}=1165\pm 44(\mathrm{stat})^{+134}_{-101}(\mathrm{syst}) \ \mu\mathrm{b}$. [...]

Measurement of the cross sections of $\rm \Xi_{c}^{0}$ and $\rm \Xi_{c}^{+}$ baryons and of the branching-fraction ratio BR($\rm \Xi_{c}^{0} \rightarrow \Xi^{-}e^+ \nu$)/BR($\rm \Xi_{c}^{0} \rightarrow \Xi^{-} \pi^{+}$) in pp collisions at $\sqrt{s}$ = 13 TeV / Acharya, Shreyasi (Calcutta, VECC) ; Adamova, Dagmar (Rez, Nucl. Phys. Inst.) ; Adler, Alexander (Goethe U., Frankfurt, Inst. Inform.) ; Adolfsson, Jonatan (Lund U.) ; Aglieri Rinella, Gianluca (CERN) ; Agnello, Michelangelo (Turin Polytechnic) ; Agrawal, Neelima (INFN, Bologna) ; Ahammed, Zubayer (Calcutta, VECC) ; Ahmad, Shakeel (Aligarh Muslim U.) ; Ahn, Sang Un (KISTI, Daejeon) et al.
The $p_{\rm T}$-differential cross sections of prompt charm-strange baryons $\rm \Xi_{c}^{0}$ and $\rm \Xi_{c}^{+}$ were measured at midrapidity (|y| < 0.5) in proton–proton (pp) collisions at a centre-of-mass energy $\sqrt{s}$ = 13 TeV with the ALICE detector at the LHC. The $\rm \Xi_{c}^{0}$ baryon was reconstructed via both the semileptonic decay ($\rm \Xi_{c}^{0} \rightarrow \Xi^{-}e^+ \nu$) and the hadronic decay ($\rm \Xi_{c}^{0} \rightarrow \Xi^{-} \pi^{+}$) channels.

Measurement of prompt D$^{0}$, $\Lambda_{c}^{+}$, and $\Sigma_{c}^{0,++}$(2455) production in pp collisions at $\sqrt{s}~=~13$ TeV / Acharya, Shreyasi (Calcutta, VECC) ; Adamova, Dagmar (Rez, Nucl. Phys. Inst.) ; Adler, Alexander (Goethe U., Frankfurt, Inst.

The $p_{\rm T}$-differential production cross sections of prompt D$^{0}$, $\Lambda_{\rm c}^{+}$, and $\Sigma_{\rm c}^{0,++}(2455)$ charmed hadrons are measured at midrapidity ($|y| < 0.5$) in pp collisions at $\sqrt{s} = 13$ TeV. This is the first measurement of $\Sigma_{\rm c}^{0,++}$ production in hadronic collisions. [...]

Investigating the role of strangeness in baryon-antibaryon annihilation at the LHC / Acharya, Shreyasi (Calcutta, VECC) ; Adamova, Dagmar (Rez, Nucl. Phys. Inst.) ; Adler, Alexander (Goethe U., Frankfurt, Inst. Inform.) ; Adolfsson, Jonatan (Lund U.) ; Aglieri Rinella, Gianluca (CERN) ; Agnello, Michelangelo (Turin Polytechnic) ; Agrawal, Neelima (INFN, Bologna) ; Ahammed, Zubayer (Calcutta, VECC) ; Ahmad, Shakeel (Aligarh Muslim U.) ; Ahn, Sang Un (KISTI, Daejeon) et al.
Annihilation dynamics plays a fundamental role in the baryon-antibaryon interaction ($\rm{B}\mbox{-}\rm{\overline{B}}$) at low-energy and its strength and range are crucial in the assessment of possible baryon bound states. Experimental data on annihilation cross sections are available for the $\rm{p}\mbox{-}\rm{\overline{p}}$ system but not in the low relative momentum region. [...]

The ALICE Collaboration reports the first fully-corrected measurements of the $N$-subjettiness observable for track-based jets in heavy-ion collisions. This study is performed using data recorded in pp and Pb$-$Pb collisions at centre-of-mass energies of $\sqrt{s} = 7$ TeV and $\sqrt{s_{\rm NN}} = 2.76$ TeV, respectively. [...]

Experimental evidence for an attractive $p-\phi$ interaction / ALICE Collaboration
This Letter presents the first experimental evidence of the attractive strong interaction between a proton and a $\phi$ meson. The result is obtained from two-particle correlations of combined $p-\phi \oplus \overline{p}-\phi$ pairs measured in high-multiplicity p-p collisions at $\sqrt{s}~=~13$ TeV by the ALICE collaboration.

Kaon-proton strong interaction at low relative momentum via femtoscopy in Pb-Pb collisions at the LHC / ALICE Collaboration
In quantum scattering processes between two particles, aspects characterizing the strong and Coulomb forces can be observed in kinematic distributions of the particle pairs. The sensitivity to the interaction potential reaches a maximum at low relative momentum and vanishing distance between the two particles. [...]
