86. Exploring strangeness enhancement through strange-hadron correlation studies at ALICE

Chiara De Martin (Universita e INFN Trieste (IT))

Multiparton interactions

oral

Interesting features in the production of strange hadrons have been revealed in heavy-ion collisions. Observations include: the development, with centrality, of a peak in the $\Lambda/K^0_S$ ratio at intermediate $p_{\rm T}$; and the enhanced yield of strange and multi-strange baryons, compared to minimum bias pp collisions. These features have been further investigated by studying pp...

21. D-meson duos in p-p and p-Pb collisions

Hannu Paukkunen (University of Jyväskylä)

Multiparton interactions

oral

The LHCb collaboration has recently measured cross sections for the simultaneous production of two charmed-particles in p-p [1] and p-Pb [2] collisions. These include opposite-sign and same-sign D-meson pairs offering, for the first time, a chance to study the interplay of single-parton (SPS) and double-parton scattering (DPS) across different collision systems.

In this talk, we discuss our...

89. Very forward energy emission as a function of particle production at midrapidity in pp and p-Pb collisions with the Zero Degree Calorimeters of ALICE

Chiara Oppedisano (Universita e INFN Torino (IT))

Multiparton interactions

oral

Using the ALICE Zero Degree Calorimeters (ZDC) it is possible to study the very forward charged and neutral energy in pp and p-Pb collisions. By correlating these measurements with the midrapidity particle production, one obtains new direct insights into the initial stages of the collisions. New results on the energy detected in neutron and proton ALICE ZDC in pp collisions at $\sqrt{s}$ = 13...
