ABOUT PREPRINTS
The Preprints collection aims to cover as far as possible all the grey literature in particle physics and its related technologies. The collection contains something like 400,000 documents, out of which about 50% can be accessed electronically. The documents originate from a variety of institutes all over the world. The collection, currently available, starts in 1979 and it has a full coverage of the arXiv.org e-Print archive since its beginning in 1991.

Astrophysical Equation-of-State Constraints on the Color-Superconducting Gap / Kurkela, Aleksi (Stavanger U.) ; Rajagopal, Krishna (MIT, Cambridge, CTP ; CERN) ; Steinhorst, Rachel (MIT, Cambridge, CTP)
We demonstrate that astrophysical constraints on the dense-matter equation of state place an upper bound on the color-superconducting gap in dense matter above the transition from nuclear matter to quark matter. [...]

Causality Bounds on Dissipative General-Relativistic Magnetohydrodynamics / Cordeiro, Ian (Illinois U., Urbana (main)) ; Speranza, Enrico (CERN ; Illinois U., Urbana (main)) ; Ingles, Kevin (Illinois U., Urbana (main)) ; Bemfica, Fábio S. (Rio Grande do Norte U.) ; Noronha, Jorge (Illinois U., Urbana (main))
We determine necessary and sufficient conditions under which a large class of relativistic generalizations of Braginskii's magnetohydrodynamics, described using Israel-Stewart theory, are causal and strongly hyperbolic in the fully nonlinear regime in curved spacetime. [...]

Higgs cross-section ( including di-Higgs ) with CMS and ATLAS / Lange, Torben (NICPB, Tallinn)
Since the discovery of the Higgs boson in 2012 by the ATLAS and CMS Collaborations a lot of progress has been made in verifying the nature of this new bosonic particle. [...]

Self-interacting dark matter solves the final parsec problem of supermassive black hole mergers / Alonso-Álvarez, Gonzalo (Toronto U. ; McGill U.) ; Cline, James M. (McGill U. ; CERN) ; Dewar, Caitlyn (McGill U.)
Evidence for a stochastic gravitational wave (GW) background, plausibly originating from the merger of supermassive black holes (SMBHs), is accumulating with observations from pulsar timing arrays. [...]
