R-Parity Violation Axiogenesis / Co, Raymond T. (Minnesota U., Theor. Phys. Inst.) ; Harigaya, Keisuke (CERN ; Princeton, Inst. Advanced Study) ; Johnson, Zachary ; Pierce, Aaron
We show that the rotation of the QCD axion field, aided by $B-L$ violation from supersymmetric $R$-parity violating couplings, can yield the observed baryon abundance. [...]

NNLO QCD corrections to weak boson fusion Higgs boson production in the $H \to b\bar b$ and $H \to WW^* \to 4l$ decay channels / Asteriadis, Konstantin (Brookhaven) ; Caola, Fabrizio (Oxford U., Theor. Phys.) ; Melnikov, Kirill (KIT, Karlsruhe, TTP) ; Röntsch, Raoul (CERN ; INFN, Milan ; Milan U.)
We compute the next-to-next-to-leading order QCD corrections to Higgs boson production in weak boson fusion followed by its decay to a $b\bar b$ pair or to a pair of leptonically-decaying $W$ bosons. [...]

Logarithmic accuracy of angular-ordered parton showers / Bewick, Gavin (Durham U., IPPP) ; Ferrario Ravasio, Silvia (Durham U., IPPP) ; Richardson, Peter (Durham U., IPPP ; CERN) ; Seymour, Michael H. (Manchester U.)
We study the logarithmic accuracy of angular-ordered parton showers by considering the singular limits of multiple emission matrix elements. This allows us to consider different choices for the evolution variable and propose a new choice which has both the correct logarithmic behaviour and improved performance away from the singular regions.

Cosmological constraints without fingers of God / Ivanov, Mikhail M. (Princeton, Inst. Advanced Study) ; Philcox, Oliver H.E. (Princeton, Inst. Advanced Study ; Princeton U., Astrophys. Sci. Dept. ; Cambridge U., DAMTP) ; Simonović, Marko (CERN) ; Zaldarriaga, Matias (Princeton, Inst. Advanced Study) ; Nishimichi, Takahiro (Kyoto U., Yukawa Inst., Kyoto ; Tokyo U., IPMU) ; Takada, Masahiro (Tokyo U., IPMU)
Non-linear redshift-space distortions ("fingers of God") are challenging to model analytically, a fact that limits the applicability of perturbation theory in redshift space as compared to real space. [...]

Detailed Calculation of Primordial Black Hole Formation During First-Order Cosmological Phase Transitions / Baker, Michael J. (Melbourne U.) ; Breitbach, Moritz (Mainz U., Inst. Phys. ; U. Mainz, PRISMA) ; Kopp, Joachim (Mainz U., Inst. Phys. ; U. Mainz, PRISMA ; CERN) ; Mittnacht, Lukas (Mainz U., Inst. Phys. ; U. Mainz, PRISMA)
We recently presented a new mechanism for primordial black hole formation during a first-order phase transition in the early Universe, which relies on the build-up of particles which are predominantly reflected from the advancing bubble wall. [...]

Flavor Symmetries and Automatic Enhancement in the 6d Supergravity Swampland / Cvetic, Mirjam (Pennsylvania U. ; Maribor U. ; CERN) ; Lin, Ling ; Turner, Andrew P.
We argue for the quantum-gravitational inconsistency of certain 6d $\mathcal{N}=(1,0)$ supergravity theories, whose anomaly-free gauge algebra $\mathfrak{g}$ and hypermultiplet spectrum $M$ were observed in arxiv:2012.01437 to be realizable only as part of a larger gauge sector $(\mathfrak{g}' \supset \mathfrak{g}, M' \supset M)$ in F-theory.
