Axion induced SUSY breaking and focus point gaugino mediation / Harigaya, Keisuke (LBNL, Berkeley ; UC, Berkeley ; CERN) ; Yanagida, Tsutomu T. (Tsung-Dao Lee Inst., Shanghai ; Tokyo U., IPMU) ; Yokozaki, Norimi (Hangzhou, Zhejiang U. ; Tohoku U.)
We consider a scenario where the supersymmetry breaking and its mediation, and the cancellation of the theta parameter of SU(3)c are all caused by a single chiral multiplet. The string axion multiplet is a natural candidate of such a single superfield. [...]

High Quality Axion in Supersymmetric Models / Choi, Gongjun (CERN) ; Yanagida, Tsutomu T. (Shanghai U. ; Tokyo U.)
In this work, we discuss how the use of the symmetries well motivated in physics beyond the Standard model (BSM) can guarantee the high quality axions. We avoid to introduce symmetries only useful for addressing the axion quality problem. [...]

Dynamically Induced Topological Inflation / Choi, Gongjun (CERN) ; Lin, Weikang (Tsung-Dao Lee Inst., Shanghai) ; Yanagida, Tsutomu T. (Tsung-Dao Lee Inst., Shanghai ; Tokyo U., IPMU)
We propose an inflation model in which the inflationary era is driven by the strong dynamics of $Sp(2)$ gauge theory. The quark condensation in the confined phase of $Sp(2)$ gauge theory generates the inflaton potential comparable to the energy of the thermal bath at the time of phase transition. [...]

Discrete R-symmetry, various energy scales, and gravitational waves / Choi, Gongjun (CERN) ; Lin, Weikang (Shanghai Jiao Tong U.) ; Yanagida, Tsutomu T. (Shanghai Jiao Tong U. ; Tokyo U.)
We present a supersymmetric model where energy scales of a discrete $R$-symmetry breaking ($Z_{6R}$) and cosmic inflation are commonly attributed to the confinement scale of a hidden $Sp(2)$ strong dynamics. Apart from these, SUSY-breaking scale, the Higgsino mass and the right-handed neutrino masses are all shown to stem from $Z_{6R}$ breaking scale inferred from CMB observables. [...]

NANOGrav results and LIGO-Virgo primordial black holes in axion-like curvaton model / Inomata, Keisuke (Chicago U., KICP) ; Kawasaki, Masahiro (Tokyo U., ICRR ; Tokyo U., IPMU) ; Mukaida, Kyohei (CERN ; DESY) ; Yanagida, Tsutomu T. (Tsung-Dao Lee Inst., Shanghai ; Shanghai Jiao Tong U. ; Tokyo U., IPMU)
We discuss a possible connection between the recent NANOGrav results and the primordial black holes (PBHs) for the LIGO-Virgo events. In particular, we focus on the axion-like curvaton model, which provides a sizable amount of PBHs and GWs induced by scalar perturbations around the NANOGrav frequency range. [...]

Flavoured $B-L$ Local Symmetry and Anomalous Rare $B$ Decays / Alonso, Rodrigo (CERN) ; Cox, Peter (Tokyo U., IPMU) ; Han, Chengcheng (Tokyo U., IPMU) ; Yanagida, Tsutomu T. (Tokyo U., IPMU)
We consider a flavoured $B-L$ gauge symmetry under which only the third generation fermions are charged. Such a symmetry can survive at low energies (~TeV) while still allowing for two superheavy right-handed neutrinos, consistent with neutrino masses via see-saw and leptogenesis. [...]

Anomaly-free local horizontal symmetry and anomaly-full rare B-decays / Alonso, Rodrigo (CERN) ; Cox, Peter (Tokyo U., IPMU) ; Han, Chengcheng (Tokyo U., IPMU) ; Yanagida, Tsutomu T. (Tokyo U., IPMU ; Hamamatsu U.)
The largest global symmetry that can be made local in the Standard Model + 3$\nu_R$ while being compatible with Pati-Salam unification is $SU(3)_H\times U(1)_{B-L}$. The gauge bosons of this theory would induce flavour effects involving both quarks and leptons, and are a potential candidate to explain the recent reports of lepton universality violation in rare B meson decays.
