Axiflavon-Higgs Unification
/ Alanne, Tommi (Heidelberg, Max Planck Inst.) ; Blasi, Simone (Heidelberg, Max Planck Inst.) ; Goertz, Florian (Heidelberg, Max Planck Inst.)
In this talk, a unified model of scalar particles that addresses the flavour hierarchies, solves the strong CP problem, delivers a dark matter candidate, and radiatively triggers electroweak symmetry breaking is discussed. The recently proposed axiflavon is embedded together with an (elementary) Goldstone Higgs-sector in a single multiplet (and thereby also a model of flavour and strong CP conservation for the latter is provided). [...]

This document summarises the current theoretical and experimental status of the di-Higgs boson production searches, and of the direct and indirect constraints on the Higgs boson self-coupling, with the wish to serve as a useful guide for the next years. The document discusses the theoretical status, including state-of-the-art predictions for di-Higgs cross sections, developments on the effective field theory approach, and studies on specific new physics scenarios that can show up in the di-Higgs final state.

Recent $\boldsymbol{B}$ Physics Anomalies - a First Hint for Compositeness?
/ Carmona, Adrián (CERN ; U. Mainz, PRISMA ; Mainz U.) ; Goertz, Florian (Heidelberg, Max Planck Inst. ; CERN)
We scrutinize the recently further strengthened hints for new physics in semileptonic $B$-meson decays, focusing on the 'clean' ratios of branching fractions $R_K$ and $R_{K^\ast}$ and examining to which pattern of new effects they point to. We explore in particular the hardly considered, yet fully viable, option of new physics in the right-handed electron sector and demonstrate how a recently proposed framework of leptons in composite Higgs setups naturally solves both the $R_K$ and $R_{K^\ast}$ anomalies via a peculiar structure of new physics effects, predicted by minimality of the model and the scale of neutrino masses.

Accessing Masses Beyond Collider Reach - in EFT
/ Goertz, Florian (Heidelberg, Max Planck Inst. ; CERN)
We demonstrate how masses of new states, beyond direct experimental reach, could nevertheless be extracted in the framework of effective field theory (EFT), given broad assumptions on the underlying UV physics, however not sticking to a particular setup nor fixing the coupling strength of the scenario. The flat direction in the $g_\ast$ vs. [...]

The Axiflavon
/ Calibbi, Lorenzo (Beijing, Inst. Theor. Phys.) ; Goertz, Florian (CERN) ; Redigolo, Diego (Tel Aviv U. ; Weizmann Inst.) ; Ziegler, Robert (Karlsruhe U., TTP) ; Zupan, Jure (CERN ; Cincinnati U.)
We show that solving the flavor problem of the Standard Model with a simple $U(1)_H$ flavor symmetry naturally leads to an axion that solves the strong CP problem and constitutes a viable Dark Matter candidate. In this framework, the ratio of the axion mass and its coupling to photons is related to the SM fermion masses and predicted within a small range, as a direct result of the observed hierarchies in quark and charged lepton masses. [...]

A flavor-safe composite explanation of $R_K$
/ Carmona, Adrian (CERN) ; Goertz, Florian (CERN)
In these proceedings we discuss a flavor-safe explanation of the anomaly found in $R_K= {\cal B}(B \to K \mu^+ \mu^-)/{\cal B}(B \to K e^+ e^-)$ by LHCb, within the framework of composite Higgs models. We present a model featuring a non-negligible degree of compositeness for all three generations of right-handed leptons, which leads to a violation of lepton-flavor universality in neutral current interactions while other constraints from quark- and lepton-flavor physics are met.
