Pion and kaon parton distribution functions from basis light front quantization and QCD evolution [PDF]
Physical Review D, 2019 We investigate the parton distribution functions (PDFs) of the pion and the kaon by combining QCD evolution with the basis light front quantization (BLFQ).

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.

Heavy hadronic molecules with pion exchange and quark core couplings: a guide for practitioners [PDF]
, 2019 We discuss selected and important features of hadronic molecules as one of promising forms of exotic hadrons near thresholds. Using examples of $D \bar D^*$ systems such as $X(3872)$ and $Z_c$, emphasis is put on the roles of the one pion exchange ...

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.

Drawing insights from pion parton distributions [PDF]
Chinese Physics C, High Energy Physics & Nuclear Physics, 2019 A symmetry-preserving continuum approach to the two valence-body bound-state problem is used to calculate the valence, glue and sea distributions within the pion; unifying them with, inter alia, electromagnetic pion elastic and transition form factors ...

In-medium pion valence distributions in a light-front model
Physics Letters B, 2017 Pion valence distributions in nuclear medium and vacuum are studied in a light-front constituent quark model. The in-medium input for studying the pion properties is calculated by the quark-meson coupling model.

Pion-Pole Contribution to Hadronic Light-By-Light Scattering in the Anomalous Magnetic Moment of the Muon. [PDF]
Physical Review Letters, 2018 The π^{0} pole constitutes the lowest-lying singularity of the hadronic light-by-light (HLBL) tensor, and thus, it provides the leading contribution in a dispersive approach to HLBL scattering in the anomalous magnetic moment of the muon (g-2)_{μ}. It is

Bootstrapping QCD Using Pion Scattering Amplitudes. [PDF]
Physical Review Letters, 2018 We consider the S-matrix bootstrap of four-dimensional scattering amplitudes with O(3) symmetry and no bound states. We explore the allowed space of scattering lengths which parametrize the interaction strength at threshold of the various scattering ...

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.
