Summary: Understanding the dynamics of strongly coupled non-Abelian gauge theories is a major challenge in theoretical physics, with applications in understanding long-distance behavior and in areas such as dynamical electroweak symmetry breaking or composite dark sectors. This review outlines the motivations and discusses how lattice methods have been adapted to provide vacuum phase diagrams of strongly coupled gauge theories with different gauge groups and fermion representations.

Summary: We explore the prospect of searching for a fermiophobic charged Higgs via the same sign trilepton signal at the LHC, and show that this signal can serve as an effective complementary search for exploring high tan beta regions.

Summary: Predictions for the Higgs masses are a distinctive feature of supersymmetric extensions of the Standard Model. The discovery and precise measurement of the Higgs boson at the LHC have spurred efforts to improve theoretical predictions for Higgs masses in supersymmetric models. The KUTS initiative aims to provide a platform for discussions and collaboration among different groups involved in these efforts to enhance the accuracy of predictions.

Summary: We discuss the implications of the CDF collaboration's high-precision measurement of the W boson mass on models with a non-standard Higgs, showing that an enhancement of more than 5% in the non-standard Higgs coupling to gauge bosons is required. This can be naturally explained in dynamical models such as the dilaton Higgs, Technicolor, and glueball Higgs. The needed composite scale between 2 and 3 TeV can also account for the muon g-2 anomaly and potential violations of lepton flavour universality.

Summary: An important task of the LHC is to study the Higgs-boson sector, particularly the reconstruction of the Higgs potential. Based on previous analyses, we evaluate the di-Higgs production cross sections within the 2-Higgs-Doublet Model type I and find regions of the allowed parameter space where the cross section differs significantly from its standard model prediction, indicating possible deviations in the Higgs self-couplings. We further analyze the sensitivity to beyond-the-standard model triple Higgs couplings and demonstrate how a possible measurement of these couplings depends on experimental uncertainties, suggesting that the HL-LHC may have the potential to detect and provide a rough measurement of these sizes.

Summary: The null results in the new physics searches at the LHC do not exclude the existence of a light fermiophobic particle, particularly in the case of fermiophobic type-I, where the parameter space satisfies multiple theoretical requirements and maintains the stability of the scalar potential at high energy scales.

Summary: We investigate a variant of the left-right symmetric model based on the SU(3)(C) circle times SU(2)(L) circle times U(1)(L) circle times SU(2)(R) circle times U(1)(R) gauge group (32121). Spontaneous symmetry breaking leads to the existence of neutral and charged massive gauge bosons apart from the standard model bosons. The masses of these bosons and their production cross sections have been studied using the results from the Large Hadron Collider (LHC). Constraints on the masses of certain scalars and fermions have also been derived from the LHC data.

Summary: In this paper, we explore the possibility of Higgs inflation in the positive stable region of the potential by introducing a nonminimally coupled induced gravity sector to the Standard Model. We show that under certain conditions, conventional Higgs inflation can be achieved by increasing the effective Planck mass during inflation through a phase transition of another scalar field chi.

Summary: The search for effective field theory deformations of the Standard Model is conducted through a global approach in the framework of the Standard Model Effective Field Theory. The analysis includes constraints on the coefficients of SMEFT operators and explores specific ultra-violet completions of the Standard Model, but does not find significant evidence for physics beyond the Standard Model.

Summary: We investigated the Higgs-Higgs scattering process and the possibility of a Higgs-Higgs bound state (Higgsonium) in Higgs potentials matching the values from the SM. By constructing the unitarized amplitude using different unitarization schemes, we found no Higgsonium state in the SM and determined the scattering lengths at tree-level and upon unitarization. We then extended the calculation for non-SM potentials and explored conditions for the formation of a bound state close to the Higgs-Higgs threshold.

Summary: This study examines the discovery of the Higgs boson at the Large Hadron Collider and its impact on the model landscape of particle physics. The research draws two main philosophical lessons: some SM alternatives may be more confirmed by the Higgs discovery than the SM itself, and the persistence of SM alternatives in the face of unfavorable evidence can be understood through the concept of a research programme.
