Hadron Physics with CLAS12

open access: yes, 2010
Hadron spectroscopy has been an essential part of the physics program with the CLAS detector in experimental Hall B at Jefferson Lab. Production of baryon and meson resonances with high energy (polarized) electron and photon beams was studied on a ...

Search for heavy Majorana or Dirac neutrinos and right-handed W gauge bosons in final states with two charged leptons and two jets at s = 13 $$ \sqrt{s}=13 $$ TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2019
A search for heavy right-handed Majorana or Dirac neutrinos N R and heavy right-handed gauge bosons W R is performed in events with a pair of energetic electrons or muons, with the same or opposite electric charge, and two energetic jets.

Numerical model of the inhomogeneous scattering by the human lens [PDF]

open access: yesCuadrado, A., Sanchez-Brea, L. M., Torcal-Milla, F. J., Quiroga, J. A., & Gomez-Pedrero, J. A. (2019). Numerical model of the inhomogeneous scattering by the human lens. Biomedical Optics Express, 10(5), 2161-2176
We present in this work a numerical model for characterizing the scattering properties of the human lens. After analyzing the scattering properties of two main scattering particles actually described in the literature through Finite Element Method simulations, we have modified a Monte Carlo bulk scattering algorithm for computing ray scattering in non ...

Electromagnetic form factors of hadrons in the time-like region

open access: yes, 2008
Hadron electromagnetic form factors of hadrons in the time-like region at the boundary of the physical region is considered. The energy behaviour of the form factor is shown to be dominantely determined by the strong hadron-antihadron interaction.

Measurements of the pp → Wγγ and pp → Zγγ cross sections and limits on anomalous quartic gauge couplings at s = 8 $$ \sqrt{s}=8 $$ TeV

open access: yesJournal of High Energy Physics, 2017
Measurements are presented of Wγγ and Zγγ production in proton-proton collisions. Fiducial cross sections are reported based on a data sample corresponding to an integrated luminosity of 19.4 fb−1 collected with the CMS detector at a center-of-mass ...

Imaging with Scattered Neutrons [PDF]

open access: yesarXiv, 2006
We describe a novel experimental technique for neutron imaging with scattered neutrons. These scattered neutrons are of interest for condensed matter physics, because they permit to reveal the local distribution of incoherent and coherent scattering within a sample.

QCD: Challenges for the Future [PDF]

open access: yes, 1996
Despite many experimental verifications of the correctness of our basic understanding of QCD, there remain numerous open questions in strong interaction physics and we focus on the role of future colliders in addressing these questions.

Search for diboson resonances in hadronic final states in 139 fb−1 of pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2019
Narrow resonances decaying into W W, W Z or ZZ boson pairs are searched for in 139 fb −1 of proton-proton collision data at a centre-of-mass energy of s $$ \sqrt{s} $$ = 13 TeV recorded with the ATLAS detector at the Large Hadron Collider from 2015 to ...

Measurement of electrons from heavy-flavour hadron decays as a function of multiplicity in p-Pb collisions at s NN $$ \sqrt{s_{\mathrm{NN}}} $$ = 5.02 TeV

open access: yesJournal of High Energy Physics, 2020
The multiplicity dependence of electron production from heavy-flavour hadron decays as a function of transverse momentum was measured in p-Pb collisions at s NN $$ \sqrt{s_{\mathrm{NN}}} $$ = 5.02 TeV using the ALICE detector at the LHC.

A fast direct imaging method for the inverse obstacle scattering problem with nonlinear point scatterers [PDF]

open access: yesarXiv, 2017
Consider the scattering of a time-harmonic plane wave by heterogeneous media consisting of linear or nonlinear point scatterers and extended obstacles. A generalized Foldy-Lax formulation is developed to take fully into account of the multiple scattering by the complex media.
