Dispersion relations for hadronic light-by-light and the muon g − 2 [PDF]
EPJ Web of Conferences, 2020 The largest uncertainties in the Standard Model calculation of the anomalous magnetic moment of the muon (g−2)µ come from hadronic effects, namely hadronic vacuum polarization (HVP) and hadronic lightby-light (HLbL) contributions.

Pion PDFs confronted by fixed-target charmonium production
AAPPS Bulletin, 2023 The pion, as the Goldstone boson of the strong interaction, is the lightest QCD bound state and responsible for the long-range nucleon-nucleon interaction inside the nucleus.

Perioperative posterior ischemic optic neuropathy (PION) after open aortic surgery
Annals of Vascular Surgery - Brief Reports and Innovations, 2022 Perioperative posterior ischemic optic neuropathy (PION) is a rare but potentially devastating condition. A correlation of PION with major surgical procedures has been established, particularly in cases of spine and cardiovascular surgery.

Transverse pion structure beyond leading twist in constituent models [PDF]
, 2016 The understanding of the pion structure as described in terms of transverse-momentum dependent parton distribution functions (TMDs) is of importance for the interpretation of currently ongoing Drell-Yan experiments with pion beams.

Physical Review Letters, 1959 In order to study the direct interaction of the incident pion with a virtual pion in the meson cloud surrounding a nucleon, the reaction pi + p yields pi /sup +/ + pi /sup -/ + n was investigated in the energy range from 260 to 430 Mev. Negative pion beams impinged on a 4-in.thick liquid hydrogen target.

Physical Review, 1960 A liquid hydrogen target was bombarded by negative pions of energies 260. 317, 371, and 427 Mev. Positive pions from the reaction pi /sup -/ + p yields pi /sup +/ + pi /sup -/ + n were dete cted by the use of a counter telescope, that selected the pi /sup +/ by its characteristic pi - mu decay.

Progress of Theoretical Physics, 1962 The modified effective range formulas for S- and P-wave pion-pion scattering which contain the effect of nucleon closed loops are derived using the chain approximation. These are extensions along the lines of Chew and Mandelstam, and Okubo and Miyamoto.

Explainable AI Insights Into EEG Classification and Its Alignment to Neural Correlates. [PDF]
Hum Brain MappWe systematically generate, filter, and cluster explanations of deep learning models of EEG data to identify universal patterns of relevance, which we validate via connections to observations from neuroscience. ABSTRACT While deep learning has drastically improved the performance of electroencephalography (EEG) analysis, it remains unclear what these ...

The pion charge radius from charged pion electroproduction [PDF]
, 2000 We analyze a low-energy theorem of threshold pion electroproduction which allows one to determine the charge radius of the pion. We show that at the same order where the radius appears, pion loops induce a correction to the momentum dependence of the ...

Generalized parton distributions of pion for non-zero skewness in AdS/QCD
Nuclear Physics B, 2018 We study the generalized parton distributions (GPDs) of pion for non-zero skewness by considering the leading |qq¯〉 Fock state component. Inspired from AdS/QCD light-front wave functions, we calculate the pion GPDs.
