An integrated airborne transmission risk assessment model for respiratory viruses: short- and long-range contributions / Henriques, Andre (CERN ; Geneva U.) ; Jia, Wei (Hong Kong U.) ; Aleixo, Luis (CERN) ; Mounet, Nicolas (CERN) ; Fontana, Luca (Unlisted, CH) ; Simniceanu, Alice (Geneva U. ; Unlisted, CH) ; Devine, James (CERN) ; Elson, Philip (CERN) ; Azzopardi, Gabriella (CERN) ; Rognlien, Markus (CERN ; Norwegian U. Sci. Tech.) et al.
This study presents an advanced airborne transmission risk assessment model that integrates both short- and long-range routes in the spread of respiratory viruses, building upon the CERN Airborne Model for Indoor Risk Assessment (CAiMIRA) and aligned with the new World Health Organization (WHO) terminology. Thanks to a two-stage exhaled jet approach, the model accurately simulates short-range exposures, thereby improving infection risk predictions across diverse indoor settings. [...]

Chiral symmetry breaking: Current experimental status and prospects / Friedrich, Jan (Munich, Tech. U.) /COMPASS Collaboration
Chiral symmetry, linked to the smallness of the quark masses compared to the QCD bound states, and its breaking pattern are exploited in effective field theory to describe a multitude of phenomena by a few low-energy constants. Those concern light-meson dynamics and decays, their couplings to photons and meson-nucleon interactions. [...]

Testing aspects of the CERN beam interlock system prior to installation in the accelerator / Colinet, Antoine (CERN) ; Martin, Christophe (CERN) ; Romera, Iván (CERN) ; Uythoven, Jan (CERN) ; Secondo, Raffaello (CERN) ; Bolton, Samuel (CERN) ; Guasch-Martinez, Josep (CERN)
The Beam Interlock System (BIS) is the backbone of the machine protection system throughout the accelerator complex at CERN, from LINAC4 to the LHC. After 15 years of flawless operation, a new version of the BIS is currently being produced and will be installed in the LHC, SPS and North Area during CERN’s Long Shutdown 3, planned to start in 2026.

Toward a pulsed antihydrogen beam for WEP tests in AEgIS / Huck, Saiva (CERN ; Hamburg U.) ; Auzins, Marcis (Latvia U.) ; Bergmann, Benedikt (IEAP CTU, Prague) ; Burian, Petr (IEAP CTU, Prague) ; Brusa, Roberto S (Trento U. ; TIFPA-INFN, Trento) ; Camper, Antoine (Oslo U.) ; Caravita, Ruggero (Trento U. ; TIFPA-INFN, Trento) ; Castelli, Fabrizio (INFN, Milan ; Milan U.) ; Ciuryło, Roman (Torun, Copernicus Astron. Ctr.) ; Consolati, Giovanni (INFN, Milan ; Milan Polytechnic) et al.
The AEg̅IS collaboration at CERN’s AD produces antihydrogen atoms in the form of a pulsed, isotropic source with a precisely defined formation time. AEg̅IS has recently undergone major upgrades to fully benefit from the increased number of colder antiprotons provided by the new ELENA decelerator and to move toward forming a horizontal beam to directly investigate the influence of gravity on the H̅ atoms, thereby probing the Weak Equivalence Principle for antimatter.

U.) ; Stoehlker, Thomas (Helmholtz Inst., Jena ; Darmstadt, GSI ; Unlisted, DE) et al.
Cryogenic Current Comparators (CCC) are ultrasensitive DC-Beam Transformers based on superconducting SQUID technology. With the aim to provide a robust and high resolution intensity measurement for application at FAIR and CERN machines, numerous steps of optimization were carried out over the last years by a collaboration of institutes specialized on the various subtopics.

Highlights from the NA61/SHINE / Pulawski, Szymon (Silesia U.) /NA61/SHINE Collaboration
NA61/SHINE is a multipurpose fixed-target facility at the CERN Super Proton Synchrotron. The main goals of the NA61/SHINE stronginteractions program are to discover the critical point of strongly interacting matter as well as to determine the properties of produced particles relevant for the study of the onset of deconfinement - the transition between the state of hadronic matter and the quark-gluon plasma.

With a unique geometry covering the forward rapidity region, the LHCb detector provides unprecedented kinematic coverage at low Bjorken-x down to x ~ 10−5 or lower. The excellent momentum resolution, vertex reconstruction and particle identification allow precision measurements down to very low hadron transverse momentum. [...]
