Unleash $Q$! cohomology, localization, and interpolation in Parisi-Sourlas supersymmetry

Parisi—Sourlas supersymmetric models are known to undergo dimensional reduction; that is, their physics is captured by models in two fewer dimensions. In this work, we revisit dimensional reduction, providing new arguments and reformulating existing proofs in terms of the cohomol...

On the Schubert calculus of the quantum K-theory for partial flag manifolds: a 3d A-model perspective

A bstract We further investigate the 3d gauged linear sigma model (GLSM)/ quantum K-theory correspondence for partial flag manifolds X ≡ Fl( k ; n ). This is a 3d uplift of the 2d GLSM/quantum cohomology correspondence with the 3d theory compactified on $$ {\mathbb{R}}^2\times {S...

News from the HL-LHC machine (and lessons learnt for future collider projects)

Abstract Operation of CERN’s present flagship project, the Large Hadron Collider (LHC), will come to an end in June 2026. After many years of successful operation in its current configuration since its startup for high-energy collisions in March 2010, the LHC will be transformed...

Review of Particle Physics *

The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,200 new measurements from 903 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and b...

Beam steering and radiation generation of electrons in bent crystals in the sub-GeV domain

Abstract We present an investigation into beam steering and radiation emission by sub-GeV electrons traversing a bent silicon crystal. Using 855, 600, and 300 MeV electron beams at the Mainz Microtron (MAMI), we explored orientational coherent effects in a 15- $$\upmu $$ <mml:mat...
