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.

The energy-dependent $\pi^+ \pi^+ \pi^+$ scattering amplitude from QCD / Hansen, Maxwell T. (CERN) ; Briceño, Raul A. (Jefferson Lab ; Old Dominion U.) ; Edwards, Robert G. (Jefferson Lab) ; Thomas, Christopher E. (Cambridge U., DAMTP) ; Wilson, David J. (Cambridge U., DAMTP)
Focusing on three-pion states with maximal isospin ($\pi^+\pi^+\pi^+$), we present the first non-perturbative determination of an energy-dependent three-hadron scattering amplitude from first-principles QCD. [...]

Search for strong electric fields in PbPb collisions at ${\sqrt {\smash [b]{s_{_{\mathrm {NN}}}}}} = $ 5.02 TeV using azimuthal anisotropy of prompt ${\mathrm{D^0}}$ and ${\mathrm{\overline{D}}{}^0}$ mesons
The strong Coulomb field created in ultrarelativistic heavy ion collisions is expected to produce a rapidity-dependent difference ($\Delta v_{2}$) in the second Fourier coefficient of the azimuthal distribution (elliptic flow, $v_{2}$) between ${\mathrm{D^0}}$ ($\mathrm{\bar{u}}\mathrm{c}$) and ${\mathrm{\overline{D}}{}^0}$ ($\mathrm{u}\mathrm{\bar{c}}$) mesons.

Optimizing large-scale structure data analysis with the theoretical error likelihood / Chudaykin, Anton ; Ivanov, Mikhail M. ; Simonović, Marko
An important aspect of large-scale structure data analysis is the presence of non-negligible theoretical uncertainties, which become increasingly important on small scales. [...]

Quarkonia production as a function of charged-particle multiplicity in pp collisions at $\sqrt{s}=13$ TeV with ALICE / Ding, Yanchun
In pp collisions at LHC energies, heavy quarks are produced in initial hard scatterings and then these quarks hadronize in either open heavy-flavor hadrons or quarkonia (e.g. [...]
