Beauty photoproduction using decays into electrons at HERA [PDF]

open access: yes, 2008
Photoproduction of beauty quarks in events with two jets and an electron associated with one of the jets has been studied with the ZEUS detector at HERA using an integrated luminosity of 120pb^-1.

PCN: a deep learning approach to jet tagging utilizing novel graph construction methods and Chebyshev graph convolutions

open access: yesJournal of High Energy Physics
Jet tagging is a classification problem in high-energy physics experiments that aims to identify the collimated sprays of subatomic particles, jets, from particle collisions and ‘tag’ them to their emitter particle.

Real time observation of a stationary magneton

open access: yesResults in Physics, 2019
The magnetic dipole field geometry of subatomic elementary particles like the electron differs from the classical macroscopic field imprint of a bar magnet. It resembles more like an eight figure or else joint double quantum-dots instead of the classical,

100 years of subatomic physics

open access: yes, 2013
By year 1911 radioactivity had been discovered for over a decade, but its origin remained a mystery. Rutherford's discovery of the nucleus and the subsequent discovery of the neutron by Chadwick started the field of subatomic physics -- a quest for ...

Measurement of identified π0 and inclusive photon second-harmonic parameter v2 and Implications for Direct Photon Production in VsNN=200 GeV Au+Au [PDF]

open access: yes, 2006
The azimuthal distribution of identified π0 and inclusive photons has been measured in VsNN=200 GeV Au+Au collisions with the PHENIX experiment at the Relativistic Heavy-Ion Collider (RHIC). The second-harmonic parameter (v2) was measured to describe the

Production of excited charm and charm-strange mesons at HERA [PDF]

open access: yes, 2009
The production of excited charm, D 1(2420)0 and D 2 * (2460)0, and charm-strange, D s1(2536)±, mesons in ep collisions was measured with the ZEUS detector at HERA using an integrated luminosity of 126 pb−1.

Charm content in jets in proton-proton collisions with the ALICE experiment at CERN-LHC [PDF]

open access: yes, 2010
Charm and bottom quarks have been proposed as probes to study partonic matter produced in high-energy heavy-ion collisions. The detailed understanding of the production mechanisms in proton-proton collisions is of considerable interest as a QCD test tool

Efficient operators for studying higher partial waves

open access: yesEPJ Web of Conferences, 2018
An extended multi-hadron operator is developed to extract the spectra of irreducible representations in the finite volume. The irreducible representations of the cubic group are projected using a coordinate-space operator.
