Summary: The resistive wall impedance is a key factor in transverse beam instabilities at the proposed Future Circular Collider hadron-hadron option. Different measures, such as octupole magnets and finite chromaticity, are suggested for Landau damping to counteract the instabilities. The study compares impedances, growth rates, and stability boundaries with those of the LHC, aiming to improve the understanding of coherent instabilities and their thresholds with energy scaling for potential highest-energy collider limits.

Summary: This study focuses on the pair production and decay of long-lived mediator particles from the decay of the standard model Higgs boson. The projected sensitivity of using different production modes and decay modes for these particles is calculated. The improvement in sensitivity with the FCC-hh detector at the 100 TeV collider experiment is also studied, with a specific focus on the muon spectrometer. Dedicated long-lived particle detector designs for the 100 TeV collider experiment are proposed and their sensitivities are studied.

Summary: The effects of lattice mismatch on heteroepitaxial growth were studied, and it was found that the structure and orientation relationships vary with substrate orientation but follow similar patterns across different systems. The magnitude of mismatch affects the manner in which it is accommodated, with edge-to-edge matching and stacking faults playing important roles. The ORs were largely independent of mismatch, while the local interfacial structure changed directly with mismatch.

Summary: Research was conducted on the potential of the 100 TeV Future Circular Collider (FCC-hh) to probe heavy neutrinos, focusing on heavy neutrino production via a U(1)(B-L) Z' gauge boson. It was found that semileptonic modes are more promising for detecting TeV-scale heavy neutrinos, with potential for detection down to 5 TeV Z' and a gauge coupling as low as g(B-L) = 10(-2). Displaced vertex searches can extend this range to heavy neutrino masses as low as 10 GeV.

Summary: The FCC-hh hadron collider will provide access to clean final states, with the Zh production channel showing sensitivity to various SMEFT operators. While O-phi q((3)) shows the best sensitivity, binning in Zh rapidity can improve sensitivity to O-phi q((1)). Estimated bounds at FCC-hh are significantly better than those at HL-LHC and future lepton colliders.

Summary: A preliminary 3D finite element analysis was conducted to evaluate the stresses and strains of the complete magnet structure for the FCC-hh, with a focus on maintaining coil pre-stress at the pole-coil interfaces. The results show peak stress of about 160 MPa in the Nb3Sn coil under nominal operation, with localized gap of less than 6 mu m at the coil-pole interface. The stress in the mechanical structure is bearable with high stress values confined to very small areas.

Summary: This article discusses the preliminary results of the 3-D electromagnetic and mechanical conceptual design for high-gradient Nb3Sn lattice quadrupoles in a post-LHC 100 TeV circular hadron collider, FCC-hh. A baseline design of the main quadrupole was selected after iterations and included in the FCC-hh Conceptual Design Report. The 3-D design of Nb3Sn coil ends, especially for small apertures, was identified as a critical phase, and addressed through electromagnetic design and winding trials.

Summary: The nu nu over bar gamma gamma couplings parametrized with the non-standard dimension-seven operators defined by the Effective Field Theory framework are investigated through the process pp ->nu nu over bar gamma at the High LuminosityLHC and the Future Circular proton-proton Collider. The effective Lagrangian of nu nu over bar gamma gamma couplings is implemented into FeynRules to generate a UFO module inserted into Madgraph to generate both background and signal events. These events are then passed through Pythia 8 for parton showering and Delphes to include realistic detector effects. The sensitivities on nu nu over bar gamma gamma couplings are obtained at 95% confidence level. We show that the analysis of the signal emerging from the process pp -> nu nu over bar gamma allows to improve constraints on nu nu over bar gamma gamma couplings given by the LEP collaboration.

Summary: Rare flavour-changing neutral-current transitions b -> s mu(+) mu(-) probe higher energy scales than what is directly accessible at the LHC. Therefore, future high-energy colliders, such as the FCC-hh and MuC, are being considered for the investigation of new physics effects in these transitions. This study compares the discovery prospects at these colliders for benchmark new physics models detectable indirectly in b -> s mu(+) mu(-) decays. It is found that a 3TeV MuC has a sensitivity comparable to the FCC-hh, but the FCC-hh has a greater potential for the discovery of a resonance. A MuC of 10TeV or higher is necessary to completely cover the parameter space suggested by the bs mu mu anomalies.

Summary: Diboson production processes are important targets for precision measurements at hadron colliders. The V h production channel with h -> b (b) over bar decay has a large cross section and can be accessed at the LHC. By combining different lepton channels and a b-tagging algorithm, we improve the analysis and obtain sensitivity to dimension-6 SMEFT operators that modify the couplings of W and Z bosons to quarks. This analysis is competitive with other bounds and has implications for new physics scales.

Summary: This study investigates the incorporation of the operator Trace Coherence (TrCoh) in polarimetric and interferometric SAR methodologies for estimating vegetation biophysical parameters. A modified inversion algorithm based on the RVoG model, employing TrCoh, demonstrates improved computational efficiency and accuracy compared to conventional methods. Validation using TanDEM-X data and reference data in a paddy rice area shows the proposed approach provides higher accuracy in vegetation height estimation.

Summary: This paper presents measurements of the relative decrease of light output during irradiation of small plastic scintillator tiles read out by silicon photomultipliers. The study found substantial temporary damage during low-temperature irradiation, regardless of oxygen concentration and wrapping material. The wrapping material had an impact on the relative light loss, with the 3M(TM) Enhanced Specular Reflector Film showing the largest loss. The light loss was less at warmer temperatures and similar to that in standard atmosphere with 3% oxygen concentration. Evidence of a plateau in the radical density was seen for the data at 0 degrees C.
