Addressing the hypertriton lifetime puzzle with ALICE at the LHC / Trogolo, Stefano (INFN, Turin ; Turin U.)
The ALICE Collaboration collected a large data sample of Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV in 2015 at the Large Hadron Collider (LHC) and the excellent particle identification (PID) capabilities allow for the detection of rarely produced (anti-)hypernuclei. [...]

Event-shape and multiplicity dependence of freeze-out radii in pp collisions at $\sqrt{s}$ = 7 TeV / Acharya, Shreyasi (Calcutta, VECC) ; Torales - Acosta, Fernando (UC, Berkeley) ; Adamova, Dagmar (Rez, Nucl. Phys. Inst.) ; Adhya, Souvik Priyam (Calcutta, VECC) ; Adler, Alexander (Goethe U., Frankfurt, Inst.

Tech., Mumbai) et al.
Two-particle correlations in high-energy collision experiments enable the extraction of particle source radii by using the Bose-Einstein enhancement of pion production at low relative momentum $q\propto 1/R$. It was previously observed that in pp collisions at $\sqrt{s}$ = 7 TeV the average pair transverse momentum $k_{\rm{T}}$ range of such analyses is limited due to large background correlations which were attributed to mini-jet phenomena.
