Measurements of top-quark pair differential cross-sections in the lepton+jets channel in pp collisions at s=13 $$ \sqrt{s}=13 $$ TeV using the ATLAS detector

open access: yesJournal of High Energy Physics, 2017
Measurements of differential cross-sections of top-quark pair production in fiducial phase-spaces are presented as a function of top-quark and tt¯ $$ t\overline{t} $$ system kinematic observables in proton-proton collisions at a centre-of-mass energy of ...

Development and dosimetric verification of static SHArc: Step‐and‐shoot carbon ion arc therapy for LETd escalation in pancreatic tumors

open access: yesMedical Physics, Volume 52, Issue 10, October 2025.
Abstract Background Carbon ion radiotherapy (CIRT) offers higher linear energy transfer (LET) and superior relative biological effectiveness, making it a promising option for treating hypoxic, radioresistant tumors. Spot‐scanning Hadron Arc (SHArc) therapy enables dose‐averaged LET (LETd) escalation in the tumor but increases planning and setup ...

The Quest for the Quark‐Gluon Plasma From the Perspective of Dynamical Models of Relativistic Heavy‐Ion Collisions

open access: yesAstronomische Nachrichten, Volume 346, Issue 7-8, September 2025.
ABSTRACT The physics of heavy‐ion collisions is one of the most exciting and challenging directions of science for the last four decades. On the theoretical side one deals with a non‐abelian field theory, while on the experimental side today's largest accelerators are needed to enable these studies.

Measurement of b-quark fragmentation properties in jets using the decay B ± → J/ψK ± in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2021
The fragmentation properties of jets containing b-hadrons are studied using charged B mesons in 139 fb −1 of pp collisions at s $$ \sqrt{s} $$ = 13 TeV, recorded with the ATLAS detector at the LHC during the period from 2015 to 2018.

Two Micron‐Size Dark Dimensions

open access: yesFortschritte der Physik, Volume 73, Issue 8, August 2025.
Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

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

open access: yesMedical Physics, Volume 52, Issue 6, Page 4862-4870, June 2025.
Abstract Background Precise 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. Two prominent techniques are PET and Prompt

Search for new phenomena in events with same-charge leptons and b-jets in pp collisions at s = 13 $$ \sqrt{s}=13 $$ TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2018
A search for new phenomena in events with two same-charge leptons or three leptons and jets identified as originating from b-quarks in a data sample of 36.1 fb−1 of pp collisions at s = 13 $$ \sqrt{s}=13 $$ TeV recorded by the ATLAS detector at the Large

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 ...
