2561 DPyC SMF false [["minutes", "Minutes"], ["notes", "Notes"], ["paper", "Paper"], ["poster", "Poster"], ["slides", "Slides"], ["summary", "Summary"]] Cinvestav ea481e58ca9c64e14d7982cb66bcd604 3312 The Division of Particles and Fields of the Mexican Physical Society (DPyC-SMF) organizes every year the Annual Meeting (RADPyC). This space is dedicated mainly for the exposure of results of graduate students and young researchers working in high energy physics and includes some review talks on the hot topics of the field. This year the meeting will be held in Auditorio José Ádem, Cinvestav, Mexico City, México. The scientific programme will consist of invited and contributed talks, and a poster session. It will begin in the morning of Wednesday 17 June and end before lunch on Friday 19 June. We will have the following invited talks: - Ana Colmenero, HAWC (UMSNH) - Jens Erler, The EW SM and constraints on NP (Mainz, PRISMA) - Iván Martínez Soler, Neutrino physics (Durham Univ.) - Cristina Oropeza, CMS (Ibero) - Antonio Ortiz, ALICE (ICN-UNAM) - Gabriel Palacios, Accelerator physics (UNAM) - Antonio Pich, Flavor physics (IFIC) - Pedro Podesta, Belle-II (UAS) - Selomit Ramírez, QCD, Loop Tree Duality, Quantum Computing (UAS) - Saúl Ramos, Flavor physics from a top-down perspective (IF-UNAM) - Alfredo Raya, NICA (UMSNH) - Eric Vázquez, DM-neutrinos (exp.) (IF-UNAM) The whole event can be followed by Zoom: https://us02web.zoom.us/j/85815121456?pwd=t1JWdqhgarEQRyewmXIEzNlkIcqU8a.1 (858 1512 1456 & 044752).

The $\Xi^{\pm}$ yield normalized to the $K^{0}_{S}$ yield is found to increase with the charged particle multiplicity for both the transverse-to-leading and the toward-leading (jet-like) regions. Although the enhancement in the transverse-to-leading region, which is sensitive to the underlying event, can be understood as due to medium(-like) effects, the enhancement for the jet-like region is striking. The effect in the jet-like region is qualitatively reproduced by PYTHIA8 with rope hadronization and EPOS LHC. The medium(-like) effects in the leading charged particle $p_{T}$ spectrum using different Monte Carlo models (AMPT, EPOS4 with and without hydrodynamics and PYTHIA8 with the color ropes mechanism) are studied. A medium(-like)-free $p_{T}$ leading threshold for angular correlation studies involving high $p_{T}$ hadrons is reported, where the leading particle $p_{T}$ spectrum is unaffected by medium(-like) effects. Since the measurements reported by ALICE were performed considering a significantly lower $p_{T}$ leading threshold, the apparent strangeness enhancement in the jet-like region can be explained in terms of a bias due to the misidentification of the leading particle.
