Inclusive hadron-hadron scattering in the Feynman gauge

open access: yesNuclear Physics B, 1985
Abstract We analyze the structure of high-energy inclusive hadron-hadron scattering in the Feynman gauge. We show that final-state interactions cancel on a graph-by-graph basis after a sum over final states. We go on to show that the leading high-energy behavior of disconnected parton scatterings in the Feynman gauge is the same as in physical gauges,

The vacuum structure in QCD and hadron-hadron scattering

open access: yesZeitschrift f�r Physik C: Particles and Fields, 1984
Standard ideas on the structure of the vacuum in QCD suggest it to be full of fluctuating color fields. We investigate the possible influence of the chromomagnetic vacuum fields on high energy hadron-hadron reactions. We suggest that high energy quarks traversing these fields will produce soft gluon and photon radiation analogous to synchrotron ...

Hadron-hadron scattering at very low energies

open access: yesInternational Journal of Modern Physics: Conference Series, 2015
In this paper we study the contribution of the incoming hadrons’ polarization to the differential cross section of the hadron scattering at the ultra low energy limit. It is shown that their polarization does not have significant effect on the differential cross section of such scattering. The polarization of the outgoing hadrons is also analyzed.

About the vacuum structure in QCD and hadron-hadron scattering [PDF]

open access: yesZeitschrift für Physik C Particles and Fields, 1985
We comment on an unconventional factorization scheme which has been recently proposed by Nachtmann and Reiter. These authors propose to take into account the influence of the vacuum structure of QCD by including a correlation in spin and colour for the partons that initiate a hard scattering process.

A Review of the Australian MRI Linac Program: From Pie in the Sky to Research Milestone

open access: yesJournal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT The Australian Magnetic Resonance Imaging (MRI) Linear Accelerator program (MRI linac) was a major research project that aimed to build and test a unique MRI linac prototype for cancer treatment. It aimed to improve radiotherapy anatomical targeting and explore physiological targeting. The purpose of this report is to summarise the development

Life, but Not as We Know It: Why Fine‐Tuning Arguments Fail

open access: yesNoûs, EarlyView.
ABSTRACT Definitions of “life” and theories of life are systematically neglected in arguments for and from fine‐tuning. Despite claims to be neutral about the definition of “life,” fine‐tuning arguments generally presuppose that life requires a form of structural complexity only afforded by physicochemical complexity of the sort with which we are ...

Search for new phenomena with top-quark pairs and large missing transverse momentum using 140 fb −1 of pp collision data at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics
A search is conducted for new phenomena in events with a top quark pair and large missing transverse momentum, where the top quark pair is reconstructed in final states with one isolated electron or muon and multiple jets.

The Gamma Factory: A New Experimental Paradigm for the Post‐HL‐LHC Era

open access: yesAnnalen der Physik, Volume 538, Issue 8, August 2026.
ABSTRACT The Gamma Factory (GF) proposal is motivated by the recognition of a largely untapped potential of the CERN accelerator complex to enable a new research program at the intersection of particle, nuclear, atomic, fundamental, and applied physics. These fields could benefit from novel experimental tools made possible by a future GF facility.
