The pT-differential cross section of ω meson production in pp collisions at √s = 13 TeV at midrapidity (|y|<0.5) was measured with the ALICE detector at the LHC, covering an unprecedented transverse-momentum range of 1.6<pT<50 GeV/c. The meson is reconstructed via the ω→π+π−π0 decay channel. [...]

/ALICE
In this letter, we present the first measurement of direct photons at the transverse momentum of 1<pT<6 GeV/c at midrapidity |η|<0.8 in inelastic and high-multiplicity proton-proton collisions at a centre-of-mass energy of √s = 13 TeV. The fraction of virtual direct photons in the inclusive virtual photon spectrum is obtained from a fit to the dielectron invariant mass spectrum. [...]

Measurements of differential two-particle number and transverse momentum correlation functions in pp collisions at √s = 13 TeV
/ Acharya, Shreyasi (Clermont-Ferrand U.) ; Agarwal, Apar (Calcutta, VECC) ; Aglieri Rinella, Gianluca (CERN) ; Aglietta, Luca (Turin U. ; INFN, Turin) ; Agnello, Michelangelo (Turin Polytechnic) ; Agrawal, Neelima (Bologna U. ; INFN, Bologna) ; Ahammed, Zubayer (Calcutta, VECC) ; Ahmad, Shakeel (Aligarh Muslim U.) ; Ahn, Sang Un (KISTI, Daejeon) ; Ahuja, Ishaan (Kosice U.) et al.
Differential two-particle normalized cumulants (R2) and transverse momentum correlations (P2) are measured as a function of the relative pseudorapidity and azimuthal angle difference (Δη,Δφ) of charged particle pairs in minimum bias pp collisions at √s = 13 TeV. The measurements use charged hadrons in the pseudorapidity region of |η|<0.8 and the transverse momentum range 0.2 <pT< 2.0 GeV/c in order to focus on soft multiparticle interactions and to complement prior measurements of these correlation functions in p-Pb and Pb-Pb collisions.

/ALICE
In this Letter, the first evidence of the 4¯Λ¯¯¯¯¯¯¯He antihypernucleus is presented, along with the first measurement at the LHC of the production of (anti)hypernuclei with mass number A=4, specifically (anti)4ΛH and (anti)4ΛHe. In addition, the antiparticle-to-particle ratios for both hypernuclei (4¯Λ¯¯¯¯H / 4ΛH and 4¯Λ¯¯¯¯¯¯¯He / 4ΛHe) are shown, which are sensitive to the baryochemical potential of the strongly-interacting matter created in heavy-ion collisions [...]

Exposing the parton-hadron transition within jets with energy-energy correlators in pp collisions at √s=5.02 TeV
/ Acharya, Shreyasi (Clermont-Ferrand U.) ; Agarwal, Apar (Calcutta, VECC) ; Aglieri Rinella, Gianluca (CERN) ; Aglietta, Luca (Turin U. ; INFN, Turin) ; Agnello, Michelangelo (Turin Polytechnic) ; Agrawal, Neelima (Bologna U. ; INFN, Bologna) ; Ahammed, Zubayer (Calcutta, VECC) ; Ahmad, Shakeel (Aligarh Muslim U.) ; Ahn, Sang Un (KISTI, Daejeon) ; Ahuja, Ishaan (Kosice U.) et al.
This paper presents a fully-corrected measurement of the energy-energy correlator (EEC) within jets in pp collisions. The EEC traces the energy flow as a highly energetic parton undergoes a QCD shower followed by the confinement of partons into hadrons, probing the correlation function of the energy flow inside jets.

/ALICE
The ALICE Collaboration at the CERN LHC has measured the inclusive production cross section of isolated photons at midrapidity as a function of the photon transverse momentum (pγT), in Pb-Pb collisions in different centrality intervals, and in pp collisions, at centre-of-momentum energy per nucleon pair of √sNN=5.02 TeV. The photon transverse momentum range is between 10-14 and 40-140 GeV/c, depending on the collision system and on the Pb-Pb centrality class. [...]

/ALICE
The production of (multi-)strange hadrons is measured at midrapidity in proton-proton (pp) collisions at √s=13 TeV as a function of the local charged-particle multiplicity in the pseudorapidity interval |η|<0.5 and of the very-forward energy measured by the ALICE Zero-Degree Calorimeters (ZDC). The latter provides information on the effective energy available for particle production in the collision once subtracted from the centre-of-mass energy. [...]
