Xsuite: an integrated beam physics simulation framework
/ Iadarola, Giovanni (CERN) ; Latina, Andrea (CERN) ; Abramov, Andrey (CERN) ; Montanari, Carlo Emilio (CERN) ; Droin, Colas (CERN) ; Di Croce, Davide (Ecole Polytechnique, Lausanne) ; Demetriadou, Despina (CERN) ; Soubelet, Felix (CERN) ; Van der Veken, Frederik (CERN) ; Sterbini, Guido (CERN) et al.
Xsuite is a modular simulation package bringing to a single flexible and modern framework capabilities of different tools developed at CERN in the past decades notably MAD-X Sixtrack Sixtracklib COMBI and PyHEADTAIL. The suite consists of a set of Python modules (Xobjects, Xpart, Xtrack, Xcoll, Xfields, Xdeps) that can be flexibly combined together and with other accelerator-specific and general-purpose python tools to study complex simulation scenarios.

Emittance and luminosity monitoring and modelling for LHC Run 3
/ Efthymiopoulos, Ilias (CERN) ; Sterbini, Guido (CERN) ; Bartosik, Hannes (CERN) ; Kostoglou, Sofia (CERN)
A comprehensive model accurately depicts and tracks emittance and luminosity evolution in the Large Hadron Collider (LHC), considering known effects like IBS, synchrotron radiation damping, coupling and incorporating data-driven factors on emittance growth and intensity losses. Used extensively in LHC Run 2, the model is updated for compatibility with new optics and operational schemes in Run 3, featuring luminosity leveling. [...]

Emittance growth studies due to Crab Cavity induced amplitude noise in the SPS
/ Fornara, Andrea (Manchester U. ; CERN) ; Trad, Georges (CERN) ; Sterbini, Guido (CERN) ; Bartosik, Hannes (CERN) ; Triantafyllou, Natalia (CERN) ; Baudrenghien, Philippe (CERN) ; Calaga, Rama (CERN) ; Appleby, Robert (Manchester U.) ; Kostoglou, Sofia (CERN) ; Levens, Thomas (CERN) et al.
In the context of the HL-LHC upgrade, RF Crab Cavities (CCs) are one of the key components to achieve the target integrated luminosity. Due to the increased bunch intensity, the collider will operate with a large crossing angle scheme to alleviate the long-range beam-beam effect. [...]
