On AdS stability

Fabio Apruzzi, G. Bruno De Luca, Alessandra Gnecchi +2

AdS supersymmetric solutions in type IIA have been classified, and they are infinitely many. Moreover, every such solution has a non-supersymmetric sister. In this paper, we st…

-deformation and long range spin chains

Balázs Pozsgay, Yunfeng Jiang, Gábor Takács

We point out that two classes of deformations of integrable models, developed completely independently, have deep connections and share the same algebraic origin. One class include…

The HepMC3 Event Record Library for Monte Carlo Event Generators

Andy Buckley, Philip Ilten, Dmitri Konstantinov +5

In high-energy physics, Monte Carlo event generators (MCEGs) are used to simulate the interactions of high energy particles. MCEG event records store the information on the simulat…

Looking for MACHOs in the Spectra of Fast Radio Bursts

Andrey Katz, Joachim Kopp, Sergey Sibiryakov +1

We explore a novel search strategy for dark matter in the form of massive compact halo objects (MACHOs) such as primordial black holes or dense mini-halos in the mass range from $1…

Photon pair production in gluon fusion: Top quark effects around threshold

Long Chen, Gudrun Heinrich, Stephan Jahn +4

We present a calculation of the NLO QCD corrections to the loop-induced production of a photon pair through gluon fusion, including massive top quarks at two loops. The two-loop vi…

Loop Dominated Signals from Neutrino Portal Dark Matter

Hiren H. Patel, Stefano Profumo, Bibhushan Shakya

We study scenarios where loop processes give the dominant contributions to dark matter decay or annihilation despite the presence of tree level channels. We illustrate this possibi…
