Coupling between transverse and longitudinal beam dynamics in the first-stage CLIC decelerator / Costa, Raul (Uppsala U.) ; Latina, Andrea (CERN) ; Olvegaard, Maja (Uppsala U.)
In this paper we present the first results of full 6D multi-bunch tracking through the new Drive-Beam decelerator lattice for the first-stage of the Compact Linear Collider (CLIC). Using the new PLACET3 tracking code, we evaluate the coupling between transverse and longitudinal dynamics in the lattice finding an indirect impact of the Drive-Beam's transverse emittance in the Main-Beam performance..

Progress of the FCC-ee optics tuning working group / Bauche, J (CERN) ; da Silva, T (IRFU, Saclay) ; Shatilov, D (CERN) ; Chance, A (IRFU, Saclay) ; Wu, Y (Ecole Polytechnique, Lausanne) ; Wang, Y (Beijing, Inst. High Energy Phys.) ; Tomas, Rogelio (CERN) ; Franchi, Andrea (ESRF, Grenoble) ; Faus-Golfe, Angeles (IJCLab, Orsay) ; Dalena, Barbara (IRFU, Saclay) et al.
FCC-ee is a proposed lepton collider with a circumference close to 100 km to produce an unprecedented amount of luminosity. The FCC-ee optics tuning working group is addressing one of the most critical aspects of the FCC-ee, that is the recovery of the optics design performance in presence of realistic imperfections.

Beam-beam interaction-induced bias to precision luminosity measurement / Wanczyk, Joanna (CERN ; Ecole Polytechnique, Lausanne) ; Buffat, Xavier (CERN) ; Dabrowski, Anne (CERN) ; Kozanecki, Witold (IRFU, Saclay) ; Pieloni, Tatiana (Ecole Polytechnique, Lausanne) ; Stickland, David (Princeton U.) ; Tomas Garcia, Rogelio (CERN) ; Wu, Yi (Ecole Polytechnique, Lausanne)
The mutual electromagnetic interaction between counter-rotating bunches crossing at the interaction points (IPs) of a particle collider has been studied since the dawn of the storage-ring era. It can result in a significant bias to absolute-luminosity calibrations determined by the van der Meer (vdM) method. [...]

Status and prospects of the HL-LHC project / Zerlauth, Markus (CERN) ; Brüning, Oliver (CERN)
This contribution summarizes the status of preparations and series production of key technologies for the HL-LHC upgrade project. The upgrade will be deployed in the LHC tunnel at the end of the currently ongoing third operational run of the LHC, by creating new underground areas and upgrading the existing LHC equipment, aiming to increase the data set collected by the main LHC experiments by another order of magnitude and starting operation as of 2029..

Status of the International Muon Collider Complex Study at 10 TeV / Skoufaris, Kyriacos (CERN) /International Muon Collider Collaboration
A circular muon collider, due to strong suppression of synchrotron radiation (muons are about 207 times heavier than electrons), can provide high energy (multi-TeV) collisions using fundamental (point-like) particles improving that way the energy frontiers of lepton-antilepton machines. A unique feature of muon colliders, is the significant increase of the luminosity per beam power with beam energy. [...]
