From Boundary Objects to Boundary Infrastructure: A Process Study of Collaboration between Big Science and Big Business

Journal of Management Studies, Volume 62, Issue 4, Page 1644-1679, June 2025.
Abstract The development of a novel boundary infrastructure for large‐scale interorganizational collaboration presents a challenge that is ill‐understood: how can individual boundary objects, which do not suffice for large‐scale collaboration and might even engender conflict, be developed into a coherent boundary infrastructure that facilitates the ...

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

Journal 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),

Effects of jet-induced medium excitation in γ-hadron correlation in A+A collisions

Physics Letters B, 2018
Coupled Linear Boltzmann Transport and hydrodynamics (CoLBT-hydro) is developed for co-current and event-by-event simulations of jet transport and jet-induced medium excitation (j.i.m.e.) in high-energy heavy-ion collisions.

Ultrafast Superradiant Scintillation from Isolated Weakly Confined Perovskite Nanocrystals

Advanced 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 ...

Hadron-hadron total cross sections and soft high-energy scattering on the lattice [PDF]

arXiv, 2011
The nonperturbative approach to soft high-energy hadron-hadron scattering, based on the analytic continuation of Euclidean Wilson-loop correlation functions, makes possible the investigation of the problem of the asymptotic energy dependence of hadron-hadron total cross sections by means of lattice calculations.

Neutrinoloser Doppelbetazerfall: Der Gral der Neutrinophysik

Physik in unserer Zeit, Volume 56, Issue 3, Page 132-137, May 2025.
Die Entschlüsselung der Neutrinoeigenschaften ist auch siebzig Jahre nach ihrer Entdeckung noch nicht abgeschlossen. Es wäre eine spektakuläre Entdeckung, sollten Neutrinos ihre eigenen Antiteilchen sein und sich folglich als Majorana‐Teilchen entpuppen. Mehrere Experimente untersuchen diese Möglichkeit.

Hadron tomography studies by generalized parton distributions and distribution amplitudes

EPJ Web of Conferences, 2017
We discuss hadron-tomography studies for the nucleon and exotic hadrons by high-energy hadron reactions. First, the constituent-counting rule is explained for determining internal quark configurations of exotic-hadron candidates by scaling properties of ...

Self-Organized Criticality in Particle Production [PDF]

arXiv, 2002
Self-Organized Criticality paradigm is a plausible picture for hadron production. A power-law behavior of hadron transverse momentum spectra and an approximate scaling observed for different hadrons in high energy hadronic collisions are discussed.

VNI-4.1: Simulation of space-time evolution of e^+e^- .... A+B collisions with parton-cascades, parton-hadron conversion, final-state hadron cascades [PDF]

Comput.Phys.Commun. 104 (1997) 70, 1998
VNI is a general-purpose Monte-Carlo event-generator, which includes the simulation of lepton-lepton, lepton-hadron, lepton-nucleus, hadron-hadron, hadron-nucleus, and nucleus-nucleus collisions. It uses the real-time evolution of parton cascades in conjunction with a self-consistent hadronization scheme, as well as the development of hadron cascades ...
