In this Letter, the first evidence of the 4ˉΛ¯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 (4ˉΛ¯H / 4ΛH and 4ˉΛ¯He / 4ΛHe) are shown, which are sensitive to the baryochemical potential of the strongly-interacting matter created in heavy-ion collisions [...]

Search for a light CP-odd Higgs boson decaying into a pair of τ-leptons in proton-proton collisions at s=13 TeV with the ATLAS detector / ATLAS Collaboration
This paper reports a search for a light CP-odd scalar resonance with a mass of 20 GeV to 90 GeV in 13 TeV proton-proton collision data with an integrated luminosity of 140 fb1 collected with the ATLAS detector at the Large Hadron Collider. The analysis assumes the resonance is produced via gluon-gluon fusion and decays into a τ+τ pair which subsequently decays into a fully leptonic μ+νμˉντeˉνeντ or e+νeˉντμˉνμντ final state. [...]

First observation of strange baryon enhancement with effective energy in pp collisions at the LHC / 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. /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. [...]

Investigating charm quark energy loss in medium with the nuclear modification factor of D0-tagged jets / 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. /ALICE
The nuclear modification factor RAA of charm jets, identified by the presence of a D0 meson among the jet constituents, has been measured for the first time in Pb-Pb collisions at a centre-of-mass energy per nucleon pair sNN=5.02 TeV with the ALICE detector at the LHC. The D0 mesons and their charge conjugates are reconstructed from the hadronic decay D0Kπ+. [...]

Measurement of f1(1285) production 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. /ALICE
This study presents the first measurement of the f1(1285) resonance using the ALICE detector in inelastic proton--proton collisions at a center-of-mass energy of 13 TeV. The resonance is reconstructed at midrapidity (|y|< 0.5) through the hadronic decay channel f1(1285)K0SK±π. [...]

Search for quasi-particle scattering in the quarkgluon plasma with jet splittings in pp and PbPb collisions at sNN = 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.
The ALICE Collaboration reports measurements of the large relative transverse momentum (kT) component of jet substructure in pp and in central and semicentral PbPb collisions at center-of-mass energy per nucleon pair sNN=5.02 TeV. Enhancement in the yield of such large-kT emissions in central PbPb collisions is predicted to arise from partonic scattering with quasi-particles of the quarkgluon plasma. [...]

The production yields of the orbitally excited charm-strange mesons Ds1(1+)(2536)+ and Ds2(2+)(2573)+ were measured for the first time in proton--proton (pp) collisions at a center-of-mass energy of s=13 TeV with the ALICE experiment at the LHC. The D+s1 and D+s2 mesons were measured at midrapidity (|y|<0.5) in minimum-bias and high-multiplicity pp collisions in the transverse-momentum interval 2<pT<24 GeV/c. [...]

The coherent J/ψ photoproduction cross section is measured for the first time at midrapidity in peripheral to semicentral Pb--Pb collisions at sNN=5.02 TeV. The centrality differential cross section dσ/dy is reported for the centrality range 40--90\%, together with the doubly-differential cross section d2σ/dydpT, extracted in two peripheral centrality classes.
