Measurement of $W^{\pm }$-boson differential cross-sections in proton–proton collisions with low pile-up data at $\sqrt{s} = 5.02$ TeV and $13\,\hbox {TeV}$ with the ATLAS detector / ATLAS Collaboration
High precision single-differential $W^\pm $-boson production cross-sections as a function of electron or muon transverse momentum $p_\textrm{T}$ or their pseudorapity $\eta $, as well as double-differential cross-sections as functions of these variables, are measured in proton–proton collisions at centre-of-mass energies $\sqrt{s}=5.02$ TeV and 13 TeV. The W-boson charge asymmetry as a function of lepton $\eta $ is also measured. [...]

Precision Physics at High-energy Colliders and Low-energy Connections / Gluza, J (Silesia U.) ; Karmakar, B (Silesia U.)
Theory and high-energy physics connected with present and future colliders need progress in precision low-energy studies. In particular, at the FCC-ee collider, a better knowledge of input parameters by roughly one order of magnitude is required for many quantities, starting with $\alpha_{QED}$, $\alpha_s$, $m_W$ , $m_Z$, $m_H$, $m_t$.

Lepton Flavour Universality Tests Using Semileptonic b-Hadron Decays at the LHCb Detector / Kutsenko, Bogdan (Marseille, CPPM) /LHCb Collaboration
This review highlights advancements in testing Lepton Flavour Universality (LFU) through semileptonic b-hadron decays at the LHCb detector. Measurements of the LFU and provide evidence of deviations from Standard Model (SM) predictions, suggesting the presence of possible New Physics (NP). [...]

A system solution for a 100 kA class high temperature superconducting line for HL-LHC and for wider energy applications / Ballarino, Amalia (CERN) ; Bailey, Wendell (U. Southampton (main)) ; Barth, Christian (CERN) ; Cruikshank, Paul (CERN) ; Gahier, Vanessa (CERN) ; Leclercq, Yann (CERN) ; Pasdeloup, Florian (CERN) ; Willering, Gerard (CERN) ; Yang, Yifeng (U. Southampton (main))
The powering of the High Luminosity magnets of the Large Hadron Collider relies on Cold Powering Systems incorporating direct current superconducting lines, called Superconducting Links, based on magnesium diboride cables. A Cold Powering System interconnects the magnets in the accelerator existing tunnel to the power converters in newly excavated galleries that are about 8 m higher than the accelerator tunnel and up to about 100 m distant from the magnets.

Gamma Factory and Precision Physics at the LHC / Płaczek, W (Jagiellonian U.) ; Krasny, M W (LPNHE, Paris ; CERN)
In this paper, we argue that the only way to improve systematic precision of W-boson mass and weak-mixing angle measurements at the LHC is to replace proton beams with isoscalar-ion beams. This results in a significant simplification of relations between W- and Z-boson production processes, with the latter serving as a precision "standard candle". [...]

High Luminosity LHC Optics Feasibility Studies for: ATLAS, ALICE, and LHCb / Patel, Pragati (Cracow, INP) ; Trzebiński, Maciej (Cracow, INP)
Properties of proton trajectories along the High Luminosity LHC beam-line in the vicinity of ATLAS, ALICE, and LHCb interaction points are discussed. Based on this, possible locations of forward proton detectors in the vicinity of these experiments were identified. [...]

Investigating irradiation effects and space charge sign inversion in n-type Low Gain Avalanche Detectors / Kraus, Veronika (CERN ; Vienna, Tech. U.) ; Biveinytė, Margarita (Vilnius U.) ; Fernandez Garcia, Marcos (Cantabria U., Santander) ; Hidalgo, Salvador (Barcelona, Inst. Microelectron.) ; Moll, Michael (CERN) ; Villegas, Jairo (Barcelona, Inst. Microelectron.) ; Wiehe, Moritz (CERN)
Low Gain Avalanche Detectors built on n-type substrate (nLGADs) have been developed by IMB-CNM to enhance the detection of low-penetrating particles, with a wide range of applications from medicine, industry to synergies with developments for high-energy physics (HEP). In this work, irradiation effects on nLGADs were investigated through proton irradiation at the CERN PS-IRRAD facility up to proton fluences of $10^{14}\,\mathrm{cm}^{-2}$. [...]

Displaced Vertex Track Trigger for the CMS Phase-2 Level-1 Trigger Upgrade / Mccarthy, Ryan Edward (Northeastern U. (main)) /CMS Collaboration
As part of the CMS Phase-2 upgrade, track information from the outer tracker will be available at the Level-1 trigger and with this comes the expanded opportunity to trigger on physics objects such as long-lived particles. Presented here is a feasibility study in calculating displaced vertex information using an extended version of the Level-1 tracking that identifies displaced tracks. [...]
