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.

Higgs to fermion decays / Cuevas Maestro, Javier (Oviedo U.) /ATLAS and CMS Collaborations
The discovery of the Higgs boson in 2012 by ATLAS and CMS collaborations fulfilled one of the main aims of the LHC, identifying a mass generation mechanism for the Standard Model (SM) giving us access to a new sector of the SM. Among others they are the Yukawa couplings, a less experimentally constrained interaction to investigate. [...]

Anti-de-Sitter space acts as an infra-red cut off for asymptotically free theories, allowing interpolation between a weakly-coupled small-sized regime and a strongly-coupled flat-space regime. [...]

Search for a resonance decaying into a scalar particle and a Higgs boson in the final state with two bottom quarks and two photons in proton-proton collisions at a center of mass energy of 13 TeV with the ATLAS detector / ATLAS Collaboration
A search for the resonant production of a heavy scalar $X$ decaying into a Higgs boson and a new lighter scalar $S$, through the process $X \to S(\to bb) H(\to \gamma\gamma)$, where the two photons are consistent with the Higgs boson decay, is performed. [...]
