Field output correction factors using a scintillation detector

open access: yesMedical Physics, Volume 52, Issue 6, Page 4844-4861, June 2025.
Abstract Background As small radiation fields play an ever‐increasing role in radiation therapy, accurate dosimetry of these fields becomes critical to ensure high quality dose calculation and treatment optimization. Despite the availability of several small volume dose detectors, small field dosimetry remains challenging.

An Updated Description of Heavy-Hadron Interactions in Geant-4 [PDF]

open access: yes, 2009
Exotic stable massive particles (SMP) are proposed in a number of scenarios of physics beyond the Standard Model. It is important that LHC experiments are able both to detect and extract the quantum numbers of any SMP with masses around the TeV scale. To

Bose-Einstein correlations of charged hadrons in proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV

open access: yesJournal of High Energy Physics, 2020
Bose-Einstein correlations of charged hadrons are measured over a broad multiplicity range, from a few particles up to about 250 reconstructed charged hadrons in proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV.

Assessing proton plans with three different beam delivery systems versus photon plans for head and neck tumors

open access: yesJournal of Applied Clinical Medical Physics, Volume 26, Issue 5, May 2025.
Abstract Purpose To compare plan quality among photon volumetric modulated arc therapy (VMAT) and intensity‐modulated proton therapy (IMPT) with robustness using three different proton beam delivery systems with various spot size (σ) ranges: cyclotron‐generated proton beams (CPBs) (σ: 2.7–7.0 mm), linear accelerator proton beams (LPBs) (σ: 2.9–5.5 mm),

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 ...

Ultrafast Superradiant Scintillation from Isolated Weakly Confined Perovskite Nanocrystals

open access: yesAdvanced Materials, Volume 37, Issue 18, May 5, 2025.
Efficiency and scintillation velocity are critical for high‐energy and medical physics. These parameters, typically conflicting in conventional scintillators, are simultaneously optimized by exploiting the giant oscillator strength of CsPbBr3 nanocrystals, leading to radiatively accelerated (multi)excitonic emission with unity efficiency without ...

High-energy behavior of hadronic total cross sections from lattice QCD

open access: yes, 2012
By means of a nonperturbative approach to soft high-energy hadron-hadron scattering, based on the analytic continuation of Wilson-loop correlation functions from Euclidean to Minkowskian theory, we shall investigate the asymptotic energy dependence of ...

Measurement of t-channel production of single top quarks and antiquarks in pp collisions at 13 TeV using the full ATLAS Run 2 data sample

open access: yesJournal of High Energy Physics
The production of single top quarks and top antiquarks via the t-channel exchange of a virtual W boson is measured in proton-proton collisions at a centre-of-mass energy of 13 TeV at the LHC using 140 fb −1 of ATLAS data.

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.
