Summary: In this study, we investigate the LHC phenomenology of a particular composite Higgs model that includes SU(3) color octet top partners and color singlet top partners, in addition to the usually considered triplet representations. We highlight that some of these unusual top partners may bear resemblance to the gluinos predicted in supersymmetric models.

Summary: The model presents a composite scotogenic model for neutrino masses, generated through loops of DOUBLE-STRUCK CAPITAL Z(2)-odd composite scalars and considering three different approaches to the couplings between neutrinos and the composite sector. If the masses of the three DOUBLE-STRUCK CAPITAL Z(2)-odd right-handed neutrinos are between the TeV and Planck scales, the model can have sizable couplings and remain viable with respect to various experimental constraints. Additionally, the lightest DOUBLE-STRUCK CAPITAL Z(2)-odd composite scalar may serve as Dark Matter via thermal freeze-out or as an asymmetric relic, featured in various models based on vacuum misalignment.

Summary: The study suggests that dark matter may be a composite state of a confining sector with an approximate scale symmetry, with interactions mediated by a pseudo-Goldstone boson. Supercooling of the confining phase transition in the early universe allows for dark matter masses up to 10^6 TeV. The precise parameter space compatible with all experimental constraints in this scenario can be tested partly by telescopes and entirely by gravitational waves.

Summary: In this study, the production of t (t) over barh and t (t) over bar hh at hadron colliders in the minimal Composite Higgs Models based on the coset SO(5)/SO(4) is investigated, with a focus on the fermionic representations 5 and 14. The analysis shows that in certain regions of parameter space, the three-body decay channel W(+)W(-)t becomes significant in the production of top partners, especially in a degenerate spectrum, and this significance is further enhanced by increasing the top partner's mass.

Summary: This study examines the precision testing of mu/e universality in B -> pi l(+) l(-) decays, showing that the ratio between muonic and electronic decay widths can be accurately predicted in a wide range of the dilepton invariant mass spectrum within and beyond the Standard Model. Numerical expressions are provided to extract precise information on short-distance dynamics in case of any deviation from universality in the observed data.

Summary: Studying the accurate transfer of information from low-energy measurements to high-energy BSM models is vital for investigating potential BSM effects at the precision frontier. In this paper, we propose the use of normalising flows to construct likelihood functions that facilitate this transfer. By constructing likelihood functions in this manner, we can generate additional samples and perform a straightforward goodness-of-fit test using a chi(2) test statistic.

Summary: This study explored the expression of claudins in human disease and two different animal models of IBD. The diverse alterations in claudin expression by epithelial and inflammatory cells were recorded in IBD and both animal models. The results suggest that claudins are not exclusively expressed by epithelial cells, and changes in claudin mRNA levels should be interpreted in the context of overall tissue alterations.

Summary: This study focuses on strongly-coupled gauge theories with mass gap in the infrared and considers a large number of fermion flavours for ultraviolet completion in composite Higgs scenario. By using holographic approach, new models are introduced to incorporate the backreaction of flavour on geometry. The mass spectrum of composite bosonic states is computed and its dependence on symmetry-breaking operators and number of flavours is analyzed, with a critical survey on regions with light dilaton. Validity of holographic approach is carefully assessed and compared with lattice simulations and Nambu-Jona-Lasinio model.

Summary: In this study, CP-Violation effects in a Composite 2-Higgs Doublet Model were investigated, showing that non-trivial complex phases in interactions can induce CPV effects in the Higgs potential and Yukawa coupling parameters. The analysis also revealed significant CPV effects even with just one complex phase in the strong sector of the model.

Summary: The next generation electron-positron colliders are designed for precision studies of the Standard Model and its extensions, particularly focusing on the Higgs sector. By studying Higgs pair production through photon collisions, potential discoveries of composite Higgs models can be made. Significant deviations from the Standard Model predictions are present in a general class of composite Higgs models, primarily due to the new quartic coupling of the Higgs to tops and the presence of a light scalar resonance.

Summary: A holographic model is used to study the dynamics and spectrum of composite Higgs models, showing encouraging results close to lattice simulations in terms of masses and decay constants. The model allows computation of additional observables not yet computed on the lattice and relaxation of quenched approximation, providing insights into the fermion content of realistic composite Higgs models. Additionally, a new holographic description of top partners is provided, predicting the spectrum for models with top partners proposed by Ferretti and Karateev.

Summary: This article discusses the applications of twisted spectral triples to the Standard Model. The initial motivation was to generate a scalar field that could stabilize the electroweak vacuum and fit the Higgs mass while satisfying the first-order condition. Ultimately, the most significant aspect of the twist lies in a new field of 1-forms related to the transition from Euclidean to Lorentzian signature.

Summary: The mechanism proposed in the article allows for obtaining multiple inflection points for the inflaton potential based on the zeros of the inflaton quartic coupling beta function and a sign change of the gauge coupling beta function. A universal inflaton potential is presented that can accommodate observational data and may be tested by upcoming cosmic microwave background observations.

Summary: This study focuses on spherically symmetric magnetic and dyonic black holes within the Standard Model and general relativity. It is found that a magnetically charged black hole with mass below 9.3 x 10^35 GeV has a cloud of electroweak gauge and Higgs fields outside the event horizon. Additionally, a hairy dyonic black hole with an integer charge may decay into a magnetic black hole plus charged fermions.

Summary: This study examines the potential existence of global vacua and changes in the Higgs potential beyond the Standard Model. The model suggests that the current metastable vacuum has a sufficiently long lifetime. It predicts variations in Higgs self-couplings and significant contributions to the signal of off-shell Higgs invisible decay.

Summary: This paper proposes a novel mechanism, catalyzed baryogenesis, to explain the observed baryon asymmetry in our universe by utilizing a ball-like catalyst's motion and its interactions with Standard Model particles. The use of the electroweak-symmetric ball model is demonstrated as an example, where electroweak sphalerons inside the ball convert baryons into leptons. The model also considers the constraints on relic balls and suggests a scenario where the balls evaporate, leading to testable levels of dark radiation.

Summary: Magnetic monopoles and Q-balls are examples of topological and nontopological solitons. A new soliton state called Q-monopole-ball, which has both topological and nontopological charges, has been discovered in a monopole sector. Stable Q-monopole-balls can contain large magnetic charges and may explain the existence of dark matter.

Summary: A study finds that inelastic scattering of dark matter off a nucleus can generate electromagnetic signals with GeV-scale energy, which can be directly detected by the IceCube detector. With detailed signal and background simulations, it is discovered that IceCube can probe dark matter masses up to one gram, assuming approximately 1 GeV deposited energy in each interaction.
