Observation of Λ hyperon local polarization in pPb collisions at sNN= 8.16 TeV
The polarization of the Λ and ¯Λ hyperons along the beam direction has been measured in proton-lead (pPb) collisions at a center-of-mass energy per nucleon pair of 8.16 TeV. [...]

Evidence for similar collectivity of high transverse momentum particles in pPb and PbPb collisions
Charged hadron elliptic anisotropies (v2) are presented over a wide transverse momentum (pT) range for proton-lead (pPb) and lead-lead (PbPb) collisions at nucleon-nucleon center-of-mass energies of 8.16 and 5.02 TeV, respectively. [...]

Flavor mixing in charmonium and light mesons with optimal distillation profiles / Urrea-Niño, Juan Andrés (Wuppertal U.) ; Finkenrath, Jacob (CERN) ; Höllwieser, Roman (Wuppertal U.) ; Knechtli, Francesco (Wuppertal U.) ; Korzec, Tomasz (Wuppertal U.) ; Peardon, Michael (Trinity Coll., Dublin)
We study the light meson - charmonium - glueball mixing using flavor-singlet meson operators built from optimal distillation profiles together with purely gluonic operators in different JPC channels at two different pion masses (420, 800 MeV) in two Nf=3+1 ensembles at close to physical charm quark mass.
