Geant4 electromagnetic physics for Run3 and Phase2 LHC / Hahnfeld, Jonas (CERN) ; Ivanchenko, Vladimir (CERN ; Princeton U.) ; Novak, Mihaly (CERN) ; Pandola, Luciano (INFN, Catania) ; Sawkey, Daren (Varian Assoc., Palo Alto)
For the new Geant4 series 11.X, the electromagnetic (EM) physics sub-libraries were revised and reorganized in view of requirements for simulation of Phase-2 LHC experiments. EM physics simulation takes a significant fraction of the available CPU during massive production of Monte Carlo events for LHC experiments. [...]

Electron Absorbed Fractions and S Factors for Intermediate Size Target Volumes: Comparison of Analytic Calculations and Monte Carlo Simulations / Kotroumpelou, Christina (Ioannina U.) ; Kyriakou, Ioanna (Ioannina U.) ; Ivanchenko, Vladimir (CERN) ; Incerti, Sebastien (LP2I, Bordeaux) ; Emfietzoglou, Dimitris (Ioannina U.)
The absorbed fraction and the S factor represent fundamental quantities in MIRD-based dosimetry of radiopharmaceutical therapy (RPT). Although Monte Carlo (MC) simulations represent the gold standard in RPT dosimetry, dose point kernels (DPK) obtained from analytic range–energy relations offer a more practical alternative for charged-particle dosimetry (β- or α-emitters).

Nonresonant central exclusive production of charged-hadron pairs in proton-proton collisions at $\sqrt{s}$ = 13 TeV / CMS and TOTEM Collaboration
The central exclusive production of charged-hadron pairs in pp collisions at a centre-of-mass energy of 13 TeV is examined, based on data collected in a special high-$ \beta^* $ run of the LHC. The nonresonant continuum processes are studied with the invariant mass of the centrally produced two-pion system in the resonance-free region, $ m_{\pi^{+}\pi^{-}} < $ 0.7 GeV or $ m_{\pi^{+}\pi^{-}} > $ 1.8 GeV.

Search for high-mass exclusive diphoton production with tagged protons in proton-proton collisions at $ \sqrt{s} = $ 13 TeV / CMS Collaboration
A search is presented for high-mass exclusive diphoton production via photon-photon fusion in proton-proton collisions at $ \sqrt{s} = $ 13 TeV in events where both protons survive the interaction. The analysis utilizes data corresponding to an integrated luminosity of 103 fb$ ^{-1} $ collected in 2016--2018 with the central CMS detector and the CMS and TOTEM precision proton spectrometer (PPS).

Search for central exclusive production of top quark pairs in proton-proton collisions at $ \sqrt{s} $ = 13 TeV with tagged protons / CMS Collaboration
A search for the central exclusive production of top quark-antiquark pairs ($ \mathrm{t} \bar{\mathrm{t}} $) is performed for the first time using proton-tagged events in proton-proton collisions at the LHC at a centre-of-mass energy of 13 TeV. The data correspond to an integrated luminosity of 29.4 fb$ ^{-1} $. [...]

A Geant4-based simulation study for a preliminary setup of the MUonE experiment / Asenov, Patrick (INFN, Perugia ; CNR IRPI, Perugia) ; Abbiendi, Giovanni (INFN, Bologna) ; Goncerz, Mateusz (Cracow, INP) ; Ivanchenko, Vladimir (CERN) ; Kucharczyk, Marcin (Cracow, INP) ; Loukas, Dimitrios (Democritos Nucl. Res. Ctr.) ; Marconi, Umberto (INFN, Bologna) ; Matteuzzi, Clara (INFN, Milan Bicocca) ; Zdybal, Milosz (Cracow, INP)
MUonE is a proposed experiment which aims at an independent and precise determination of the leading hadronic contribution to the muon $g-2$, based on the measurement of the hadronic running of the electromagnetic coupling in the space-like region. This can be achieved by measuring with extremely high accuracy the shape of the differential cross section of the $\mu e$ elastic scattering, using a 160$\,$GeV muon beam available at CERN, off atomic electrons of a light target.

Geant4 simulation model of electromagnetic processes in oriented crystals for accelerator physics / Sytov, Alexei (INFN, Ferrara ; KISTI, Daejeon) ; Bandiera, Laura (INFN, Ferrara) ; Cho, Kihyeon (KISTI, Daejeon) ; Hwang, Soonwook (KISTI, Daejeon) ; Cirrone, Giuseppe Antonio Pablo (INFN, LNS) ; Pandola, Luciano (INFN, LNS) ; Guatelli, Susanna (Wollongong U.) ; Rosenfeld, Anatoly (Wollongong U.) ; Haurylavets, Viktar (Minsk, Inst. Nucl. Problems) ; Tikhomirov, Victor (Minsk, Inst. Nucl. Problems) et al.
Electromagnetic processes of charged particles interaction with oriented crystals provide a wide variety of innovative applications such as beam steering, crystal-based extraction/collimation of leptons and hadrons in an accelerator, a fixed-target experiment on magnetic and electric dipole moment measurement, X-ray and gamma radiation source for radiotherapy and nuclear physics and a positron source for lepton and muon colliders, a compact crystalline calorimeter as well as plasma acceleration in the crystal media. One of the main challenges is to develop an up-to-date, universal and fast simulation tool to simulate these applications. [...]

A search for new physics in central exclusive production using the missing mass technique with the CMS detector and the CMS-TOTEM precision proton spectrometerA search for new physics in central exclusive production using the missing mass technique with the CMS detector and the CMS-TOTEM precision proton spectrometer / CMS Collaboration
A generic search is presented for the associated production of a Z boson or a photon with an additional unspecified massive particle X, $ \mathrm{p}\mathrm{p}\to \mathrm{p}\mathrm{p} +\mathrm{Z}/\gamma+\mathrm{X} $, in proton-tagged events from proton-proton collisions at $ \sqrt{s}= $ 13 TeV, recorded in 2017 with the CMS detector and the CMS-TOTEM precision proton spectrometer. The missing mass spectrum is analysed in the 600-1600 GeV range and a fit is performed to search for possible deviations from the background expectation. [...]

Search for high-mass exclusive $ \gamma\gamma \to \mathrm{W}\mathrm{W} $ and $ \gamma\gamma \to \mathrm{Z}\mathrm{Z} $ production in proton-proton collisions at $ \sqrt{s}= $ 13 TeV / CMS Collaboration
A search is performed for exclusive high-mass $ \gamma\gamma \to \mathrm{W}\mathrm{W} $ and $ \gamma\gamma \to \mathrm{Z}\mathrm{Z} $ production in proton-proton collisions using intact forward protons reconstructed in near-beam detectors, with both weak bosons decaying into boosted and merged jets. The analysis is based on a sample of proton-proton collisions collected by the CMS and TOTEM experiments at $ \sqrt{s}= $ 13 TeV, corresponding to an integrated luminosity of 100 fb$ ^{-1} $. [...]
