Metastable Nonextremal Antibranes / Armas, J. ; Nguyen, N. ; Niarchos, V. ; Obers, N. A. ; et al
We find new and compelling evidence for the metastability of supersymmetry-breaking states in holographic backgrounds whose consistency has been the source of ongoing disagreements in the literature. [...]

Light Dark Matter at Neutrino Experiments / Ema, Yohei ; Sala, Filippo ; Sato, Ryosuke
Sub-GeV dark matter particles up-scattered by cosmic rays gain enough kinetic energy to pass the thresholds of large volume detectors on Earth. [...]

Elliptic Flow of Heavy Quarkonia in pA Collisions / Zhang, Cheng ; Marquet, Cyrille ; Qin, Guang-You ; Wei, Shu-Yi ; et al
Using the dilute-dense factorization in the color glass condensate framework, we investigate the azimuthal angular correlation between a heavy quarkonium and a charged light hadron in proton-nucleus collisions. [...]

Kink-Kink and Kink-Antikink Interactions with Long-Range Tails / Christov, Ivan C. ; Decker, Robert J. ; Demirkaya, A. ; Gani, Vakhid A. ; et al
In this Letter, we address the long-range interaction between kinks and antikinks, as well as kinks and kinks, in φ2n+4 field theories for n>1. [...]

Novel Direct Detection Constraints on Light Dark Matter / Bringmann, Torsten ; Pospelov, Maxim
All attempts to directly detect particle dark matter (DM) scattering on nuclei suffer from the partial or total loss of sensitivity for DM masses in the GeV range or below. [...]

Strong Running Coupling from the Gauge Sector of Domain Wall Lattice QCD with Physical Quark Masses / Zafeiropoulos, S. ; Boucaud, Ph. ; De Soto, F. ; Rodríguez-Quintero, J. ; et al
We report on the first computation of the strong running coupling at the physical point (physical pion mass) from the ghost-gluon vertex, computed from lattice simulations with three flavors of domain wall fermions. [...]

Cherenkov Radiation from the Quantum Vacuum / Macleod, Alexander J. ; Noble, Adam ; Jaroszynski, Dino A.
A charged particle moving through a medium emits Cherenkov radiation when its velocity exceeds the phase velocity of light in that medium. [...]
