Hadron-Hadron interactions from Nf=2+1+1 lattice QCD: I=3/2 πK scattering length [PDF]

open access: yesPhysical Review D, 2018
In this paper we report on results for the s-wave scattering length of the $\pi$-$K$ system in the $I=3/2$ channel from $N_f=2+1+1$ Lattice QCD. The calculation is based on gauge configurations generated by the European Twisted Mass Collaboration with ...

A comparative analysis of GEANT4, MCNP6 and FLUKA on proton‐induced gamma‐ray simulation

open access: yesMedical Physics, EarlyView.
Abstract BackgroundPrecise range verification is essential in proton therapy to minimize treatment margins due to the steep dose fall‐off of proton beams. The emission of secondary radiation from nuclear reactions between incident particles and tissues stands out as a promising method for range verification.

Parton Models and Deep Hadron‐Hadron Scattering [PDF]

open access: yesAIP Conference Proceedings, 1973
We review the recent applications of various parton models, to the problem of hadron‐hadron scattering at large momentum transfers. Models which allow direct parton‐parton interaction as well as those that do not are considered. Predictions for the structure of hadronic final states (whether or not transverse jets exist), associated multiplities, and ...

Out‐of‐field neutron radiation from clinical proton, helium, carbon, and oxygen ion beams

open access: yesMedical Physics, EarlyView.
Abstract Background In hadron therapy, out‐of‐field doses, which may in the long‐term cause secondary cancers, are mostly due to neutrons. Very recently, 4He and 16O beams have been added to protons and 12C ions for clinical therapy. Purpose The focus of this article is to compare secondary neutron doses produced by clinical protons, 4He, 12C, and 16O ...

GLUON BREMSTRAHLUNG EFFECTS IN LARGE p HADRON-HADRON SCATTERING [PDF]

open access: yesAIP Conference Proceedings, 1982
We consider effects of parton (primarily gluon) bremstrahlung in the initial and final states of high transverse momentum hadron‐hadron scattering. Monte Carlo calculations based on conventional QCD parton branching and scattering processes are presented. The calculations are carried only to the parton level in the final state.

Search for direct production of electroweakinos in final states with missing transverse momentum and a Higgs boson decaying into photons in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2020
A search for a chargino-neutralino pair decaying via the 125 GeV Higgs boson into photons is presented. The study is based on the data collected between 2015 and 2018 with the ATLAS detector at the LHC, corresponding to an integrated luminosity of 139 fb

Search for dark matter in events with missing transverse momentum and a Higgs boson decaying into two photons in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2021
A search for dark-matter particles in events with large missing transverse momentum and a Higgs boson candidate decaying into two photons is reported. The search uses 139 fb −1 of proton-proton collision data collected at s $$ \sqrt{s} $$ = 13 TeV with ...

A New Fracture Function Approach to QCD Initial State Radiation [PDF]

open access: yes, 2007
Ordinary fracture functions, describing hadrons production in the deep inelastic scattering target fragmentation region, are generalized to account for the production of hadrons in arbitrary number, thus offering a renewed framework for dealing with QCD ...

Nuclear Physics in the Era of Quantum Computing and Quantum Machine Learning

open access: yesAdvanced Quantum Technologies, EarlyView.
The use of QML in the realm of nuclear physics at low energy is almost nonexistent. Three examples of the use of quantum computing and quantum machine in nuclear physics are presented: the determination of the phase/shape in nuclear models, the calculation of the ground state energy, and the identification of particles in nuclear physics experiments ...

In vivo dosimetry for proton therapy: A Monte Carlo study of the Gadolinium spectral response throughout the course of treatment

open access: yesMedical Physics, Volume 52, Issue 4, Page 2412-2424, April 2025.
Abstract Background In proton radiotherapy, the steep dose deposition profile near the end of the proton's track, the Bragg peak, ensures a more conformed deposition of dose to the tumor region when compared with conventional radiotherapy while reducing the probability of normal tissue complications.
