Field output correction factors using a scintillation detector
Medical Physics, EarlyView.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.

Exotic hadrons from BESIII [PDF]
EPJ Web of Conferences, 2019 We report the progress in the study of the exotic hadrons, also called XYZ states, at BESIII experiment with its unique data samples in e+ e− annihilation at center-of-mass energies of 3.8–4.6 GeV.

Dynamically generated hadron resonances [PDF]
arXiv, 2020 Recent developments in hadron spectroscopy triggers the discussion on various exotic configurations beyond the simple three-quark state for baryons and quark-anti-quark pair for mesons. In particular, the states observed near a two-hadron threshold are often regarded as candidates of hadronic molecules, which are made of constituent hadrons and ...

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

Displaced B c − mesons as an inclusive signature of weakly decaying double beauty hadrons
Journal of High Energy Physics, 2019 The recent discovery, by the LHCb collaboration, of the Ξ cc + + doubly charmed baryon, has renewed interest in the spectroscopy of doubly heavy hadrons. Experimentally, however, searches for such states appear highly challenging. The reconstructed final

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

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

Hadron spectroscopy and interactions from lattice QCD
EPJ Web of Conferences, 2016 Lattice QCD approach to study the hadronic resonances and exotic hadrons is described at an introductory level. The main challenge is that these states decay strongly via one or more decay channels, and they often lie near thersholds.
