Optimization of muon suppression using sweeper magnets for the Forward Physics Facility at the HL-LHC / Ariga, Akitaka (Bern U. ; Chiba U.) ; Ariga, Tomoko (Kyushu U., Fukuoka (main)) ; Atkinson, Jeremy (Bern U.) ; Boyd, Jamie (CERN) ; Chinone, Kohei (Chiba U.) ; Dobre, Radu (Bucharest, Inst. Space Science) ; Firu, Elena (Bucharest, Inst. Space Science) ; Fujimori, Haruhi (Chiba U.) ; Gibson, Stephen (Royal Holloway, U. of London) ; Hayakawa, Daiki (Chiba U.) et al.
The Forward Physics Facility (FPF) at the High-Luminosity LHC (HL-LHC) will enable high-statistics measurements of TeV-scale neutrinos, but the intense flux of forward muons poses a major challenge for neutrino detectors in the far-forward region. [...]

Leptonic flavour transfer : a new window on flavour gauge symmetries / Darmé, L. (IP2I, Lyon) ; Fardeau, N. (IP2I, Lyon) ; Mahmoudi, F. (IP2I, Lyon ; CERN ; ENS, Lyon, Lab. Phys.) ; Palmiotto, M. (Oslo U.)
New flavour non-abelian gauge groups, which may arise as part of a fundamental theory of flavour, can lead to distinctive flavour-transfer processes. [...]

Nuclear parton distributions and nuclear shadowing / Paakkinen, Petja (CERN) ; Guzey, Vadim (Jyvaskyla U. ; Helsinki U.)
In this contribution, we review the physics and phenomenology of nuclear parton distribution functions (PDFs), with a particular focus on the small-x region of nuclear shadowing. [...]

Search for new physics using single-lepton events with high multiplicities of jets and b jets in proton-proton collisions at $ \sqrt{s}= $ 13 TeV / CMS Collaboration
This analysis investigates the existence of physics beyond the standard model in events characterized by high multiplicities of jets and bottom quark (b) jets in the single-lepton final state, without a requirement on missing transverse momentum [...]

Analysis of the $ C\!P $ structure of the Yukawa coupling between the Higgs boson and tau leptons in proton-proton collisions at $ \sqrt{s}= $ 13.6 TeV
This paper presents a measurement of the charge-parity ( $ C\!P $) structure of the Yukawa coupling between the Higgs boson (H) and tau leptons, using proton-proton collision data at $ \sqrt{s}= $ 13.6 TeV recorded with the CMS detector at the LHC, corresponding to an integrated luminosity of 62.4 fb$ ^{-1} $.

How traversable is a traversable wormhole? / Freivogel, Ben (U. Amsterdam, GRAPPA) ; Fumagalli, Alessandro (U. Amsterdam, GRAPPA) ; Tomašević, Marija (CERN)
To answer the above question, we study low-frequency scattering in the four-dimensional traversable wormhole of Maldacena, Milekhin, and Popov. [...]

Constraining the real scalar singlet extension of the SM / Bosse, Moritz (Dortmund U.) ; Hiller, Gudrun (Dortmund U. ; CERN) ; Litim, Daniel (Sussex U.) ; Maltoni, Fabio (CERN ; Louvain U., CP3 ; Bologna U.) ; Ramsey-Musolf, Michael J. (Tsung-Dao Lee Inst., Shanghai ; Shanghai Jiao Tong U. ; Shanghai Jiaotong U. ; Caltech) ; Tentori, Simone (Louvain U., CP3) ; Xia, Guotao (Tsung-Dao Lee Inst., Shanghai ; Shanghai Jiao Tong U. ; Shanghai Jiaotong U.)
The real scalar singlet extension of the standard model provides a minimal framework in which the Higgs sector can realise a strong first-order electroweak phase transition and improve the stability of the electroweak vacuum. [...]

CMB Constraints on Pre-Inflationary Axion Dark Matter Isocurvature / Petretti, Catherine (Harvard-Smithsonian Ctr. Astrophys. ; MIT) ; Singh, Praniti (Brown U. (main)) ; Braglia, Matteo (CERN) ; Chen, Xingang (Harvard-Smithsonian Ctr. Astrophys. ; MIT) ; Fan, JiJi (Brown U. (main) ; Brown U.) ; Li, Lingfeng (Nanjing Normal U. ; ICTP-AP, Beijing)
Although measurements of the Cosmic Microwave Background (CMB) are consistent with a nearly scale-invariant primordial spectrum of adiabatic perturbations, in which the energy densities of different components (radiation, baryons, and dark matter) fluctuate proportionally, there could also exist isocurvature perturbations, in which density fluctuations of the individual components differ from the adiabatic mode.
