Constraints on Single-Field Inflation from the BOSS Galaxy Survey / Cabass, Giovanni (Princeton, Inst. Advanced Study) ; Ivanov, Mikhail M. ; Philcox, Oliver H.E. ; Simonović, Marko ; Zaldarriaga, Matias
Non-local primordial non-Gaussianity (NLPNG) is a smoking gun of interactions in single-field inflationary models, and can be written as a combination of the equilateral and orthogonal templates. [...]

Singlet channel scattering in a Composite Higgs model on the lattice / Drach, Vincent (Plymouth U.) ; Fritzsch, Patrick (Plymouth U. ; Trinity Coll., Dublin) ; Rago, Antonio (Plymouth U. ; CERN) ; Romero-López, Fernando (Valencia U., IFIC)
We present the first calculation of the scattering amplitude in the singlet channel beyond QCD. The calculation is performed in $SU(2)$ gauge theory with $N_f=2$ fundamental Dirac fermions and based on a finite-volume scattering formalism. [...]

Dark radiation constraints on light primordial black holes / Auffinger, Jérémy ; Arbey, Alexandre ; Sandick, Pearl ; Haghi, Barmak Shams Es ; Sinha, Kuver (Vrije U., Amsterdam ; Nikhef, Amsterdam)
Light black holes could have formed in the very early universe through the collapse of large primordial density fluctuations. These primordial black holes (PBHs), if light enough, would have evaporated by now because of the emission of Hawking radiation; thus they could not represent a sizable fraction of dark matter today. [...]

Flavour anomalies in supersymmetric scenarioswith non-minimal flavour violation / Boussejra, M.A. ; Mahmoudi, F. ; Uhlrich, G.
Motivated by tensions between experimental measurements and SM predictions in $b\to s \ell^+\ell^-$ transitions, we present the first study of non-minimal flavour violating MSSM scenarios contributing to the relevant Wilson coefficients to address the observed anomalies using SuperIso and MARTY We calculate the full one-loop analytical contributions of the general MSSM to Wilson coefficients relevant for flavor anomalies, together with the anomalous muon magnetic dipole moment $(g-2)_\mu$.

Discrete $R$-symmetry, Various Energy Scales and Gravitational Waves / Choi, Gongjun ; Lin, Weikang (Shanghai Jiao Tong U.) ; Yanagida, Tsutomu T.
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. [...]
