Electroweak corrections and Bloch-Nordsieck violations in 2-to-2 processes at the LHC

W. J. Stirling, E. Vryonidou

We consider the effect of next-to-leading order (NLO) electroweak corrections to Standard Model 2-to-2 processes, taking into account the potentially large double logarithms origin…

A superheated Bose-condensed gas

Alexander L. Gaunt, Richard J. Fletcher, Robert P. Smith +1

Our understanding of various states of matter usually relies on the assumption of thermodynamic equilibrium. However, the transitions between different phases of matter can be stro…

On the method of typical bounded differences

Lutz Warnke

Concentration inequalities are fundamental tools in probabilistic combinatorics and theoretical computer science for proving that random functions are near their means. Of particul…

Omitting types and AF algebras

Kevin Carlson, Enoch Cheung, Ilijas Farah +5

We give model-theoretic characterizations of UHF algebras and of AF algebras as C*-algebras that omit certain sets of types.

Confinement of quarks and valence gluons in SU(N) Yang-Mills-Higgs models

L. E. Oxman

In this work, we analyze a class of Yang-Mills models containing adjoint Higgs fields, with SU(N) symmetry spontaneously broken down to Z(N), showing they contain center vortices,…

The anatomy of an extreme starburst within 1.3Gyr of the Big Bang revealed by ALMA

C. L. Carilli, D. Riechers, F. Walter +5

We present further analysis of the [CII] 158m fine structure line and thermal dust continuum emission from the archetype extreme starburst/AGN group of galaxies in the early Uni…

Lambda_b -> Lambda l+ l- form factors and differential branching fraction from lattice QCD

William Detmold, C. -J. David Lin, Stefan Meinel +1

We present the first lattice QCD determination of the transition form factors that govern the rare baryonic decays at leading order in heavy-quark ef…

Bright radio emission from an ultraluminous stellar-mass microquasar in M31

Matthew J. Middleton, James C. A. Miller-Jones, Sera Markoff +34

A subset of ultraluminous X-ray sources (those with luminosities < 10^40 erg/s) are thought to be powered by the accretion of gas onto black holes with masses of ~5-20 M_solar, pro…

Quantum simulation of low-temperature metallic liquid hydrogen

Ji Chen, Xin-Zheng Li, Qianfan Zhang +5

Experiments and computer simulations have shown that the melt-ing temperature of solid hydrogen drops with pressure above about 65 GPa, suggesting that a liquid state might exist a…

Stationary holographic plasma quenches and numerical methods for non-Killing horizons

Pau Figueras, Toby Wiseman

We explore use of the harmonic Einstein equations to numerically find stationary black holes where the problem is posed on an ingoing slice that extends into the interior of the bl…

Majorana-Klein hybridization in topological superconductor junctions

B. Béri

We present a powerful and general approach to describe the coupling of Majorana fermions to external leads, of interacting or non-interacting electrons. Our picture has the Klein f…

Bose-Einstein condensation of atoms in a uniform potential

Alexander L. Gaunt, Tobias F. Schmidutz, Igor Gotlibovych +2

We have observed Bose-Einstein condensation of an atomic gas in the (quasi-)uniform three-dimensional potential of an optical box trap. Condensation is seen in the bimodal momentum…

SUPER-Screening

Philippe Brax, Anne-Christine Davis, Jeremy Sakstein

We present a framework for embedding scalar-tensor models of screened modifed gravity such as chameleons, symmetrons and environmental dilatons into global supersymmetry. This achi…

A Robust Measure of Cosmic Structure beyond the Power-Spectrum: Cosmic Filaments and the Temperature of Dark Matter

Danail Obreschkow, Chris Power, Martin Bruderer +1

We discover that the mass of dark matter particles mDM is imprinted in phase-correlations of the cosmic density field more significantly than in the 2-point correlation. In particu…

Exoplanets Beyond the Solar Neighbourhood: Galactic Tidal Perturbations

Dimitri Veras, N. Wyn Evans

The majority of Milky Way extrasolar planets likely reside within a few kpc of the Galactic centre. The Galactic tidal forces acting on planets scale inversely with radius in the G…
