Due to a planned intervention the CERN Document Server website will be read only (no new submission or restricted content) from Tuesday, June 29th at 13:30 CEST to Wednesday, June 30th at 9:30 CEST.
The website will be shortly unavailable at the beginning and at the end of the intervention.

 Experimental facilities in Latin America / Dib, C O (CCTVal, Valparaiso ; Valparaiso Ctr. Sci. Tech.) These lecture notes briefly describe the current and planned experimental facilities for high-energy physics research in Latin America. The list is not exhaustive nor the descriptions are complete, but I tried to select some of the most representative facilities and large international experiments at the time.

 HPS@L1 algorithm for the upgraded CMS level-1 hadronic tau trigger for the HL-LHC / Bhowmik, Sandeep (NICPB, Tallinn) /CMS Collaboration The High-Luminosity LHC will open an unprecedented window on the weak-scale nature of the universe, providing high-precision measurements of the standard model as well as searches for new physics beyond the standard model. The Compact Muon Solenoid (CMS) experiment is planning to replace entirely its trigger and data acquisition system to achieve this ambitious physics program.

 Beam-test evaluation of the precision timing capabilities of a CMS HGCAL prototype / Buchot Perraguin, Axel (Ecole Polytechnique) /CMS Collaboration The existing CMS endcap calorimeters will be replaced by a High Granularity Calorimeter (HGCAL) for operation at the High Luminosity (HL) LHC which will start in 2027. Radiation hardness and excellent physics performance will be achieved by utilising silicon pad sensors and SiPM-on-scintillator tiles with high transverse and longitudinal segmentation.

 Probe $p_T$-dependent flow vector fluctuations with ALICE / Nielsen, Emil Gorm (Bohr Inst.) /ALICE Collaboration One of the main goals of ultra-relativistic nuclear collisions is to create a new state of matter called the quark-gluon plasma (QGP) and study its properties. One of the experimental observables is the anisotropic flow $v_n$, defined as the correlation of the azimuthal angle of each particle with respect to a common symmetry plane $\Psi_n$.

 Activity on the Sextupole Round Coil Superferric Magnet Prototype at LASA / Mariotto, Samuele ; Leone, Augusto ; Paccalini, Antonio ; Pasini, Alessandro ; Pedrini, Danilo ; Quadrio, Mauro ; Sorbi, Massimo ; Statera, Marco ; Todero, Maurizio ; Valente, Riccardo The LASA Laboratory (INFN, Milan, Italy) is developing an unconventional type of superferric magnets suitable to arbitrary multipole order, which we refer to as round coil superferric magnets. This type of magnet is suitable for strain-sensitive superconductors because it uses round coils with large bending radius to create the magnetic field, while the round yoke with arbitrary multipoles is able to create the desired harmonic component for the magnet.
