Light and strange vector resonances from lattice QCD at physical quark masses
/ Boyle, Peter (Brookhaven ; Edinburgh U.) ; Erben, Felix (Edinburgh U. ; CERN) ; Gülpers, Vera (Edinburgh U.) ; Hansen, Maxwell T. (Edinburgh U.) ; Joswig, Fabian (Edinburgh U.) ; Lachini, Nelson Pitanga (Edinburgh U. ; Cambridge U., DAMTP) ; Marshall, Michael (Edinburgh U.) ; Portelli, Antonin (Edinburgh U. ; CERN ; RIKEN AICS, Kobe)
We present the first ab initio calculation at physical quark masses of scattering amplitudes describing the lightest pseudoscalar mesons interacting via the strong force in the vector channel. [...]

Physical-mass calculation of $\rho(770)$ and $K^*(892)$ resonance parameters via $\pi \pi$ and $K \pi$ scattering amplitudes from lattice QCD
/ Boyle, Peter (Brookhaven ; Edinburgh U.) ; Erben, Felix (Edinburgh U. ; CERN) ; Gülpers, Vera (Edinburgh U.) ; Hansen, Maxwell T. (Edinburgh U.) ; Joswig, Fabian (Edinburgh U.) ; Lachini, Nelson Pitanga (Edinburgh U. ; Cambridge U., DAMTP) ; Marshall, Michael (Edinburgh U.) ; Portelli, Antonin (Edinburgh U. ; CERN ; RIKEN AICS, Kobe)
We present our study of the $\rho(770)$ and $K^*(892)$ resonances from lattice quantum chromodynamics (QCD) employing domain-wall fermions at physical quark masses. [...]

Candidate de Sitter Vacua
/ McAllister, Liam (Cornell U., Phys. Dept.) ; Moritz, Jakob (CERN) ; Nally, Richard (Cornell U., Phys. Dept.) ; Schachner, Andreas (Cornell U., Phys. Dept. ; Munich U., ASC)
We construct compactifications of type IIB string theory that yield, at leading order in the $\alpha^\prime$ and $g_s$ expansions, de Sitter vacua of the form envisioned by Kachru, Kallosh, Linde, and Trivedi. [...]

LO, NLO, and NNLO Parton Distributions for LHC Event Generators
/ Cruz-Martinez, Juan (CERN) ; Forte, Stefano (INFN, Milan ; Milan U.) ; Laurenti, Niccolo (INFN, Milan ; Milan U.) ; Rabemananjara, Tanjona R. (Vrije U., Amsterdam ; NIKHEF, Amsterdam) ; Rojo, Juan (Vrije U., Amsterdam ; NIKHEF, Amsterdam)
We present NNPDF4.0MC, a variant of the NNPDF4.0 set of parton distributions (PDFs) at LO, NLO and NNLO, with and without inclusion of the photon PDF, suitable for use with Monte Carlo (MC) event generators, which require PDFs to satisfy additional constraints in comparison to standard PDF sets.

Heavy-to-light form factors to three loops
/ Fael, Matteo (CERN) ; Huber, Tobias (Siegen U.) ; Lange, Fabian (Zurich U. ; PSI, Villigen) ; Müller, Jakob (Siegen U.) ; Schönwald, Kay (Zurich U.) ; Steinhauser, Matthias (KIT, Karlsruhe, TTP)
We compute three-loop corrections of $\mathcal{O}(\alpha_{s}^3)$ to form factors with one massive and one massless quark coupling to an external vector, axialvector, scalar, pseudoscalar, or tensor current. [...]
