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.

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-pion scattering amplitude [PDF]
Physical Review D, 2005 We obtain reliable ππ scattering amplitudes consistent with experimental data, both at low and high energies, and fulfilling appropriate analyticity properties. We do this by first fitting experimental low energy [s^(1/2) ≤ (1.42 GeV] phase shifts and inelasticities with expressions that incorporate analyticity and unitarity.

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.

The investigation of K+π−, π+K− and π+π− atoms
EPJ Web of Conferences, 2016 Theory, using Low Energy QCD, predicts with high precision the pion-pion and pion-kaon scattering lengths. There is accurate relation between K+π− and π+K− atoms lifetime and pion-kaon S-wave scattering lengths with isospin 1/2 and 3/2.

Pion wave-function as a bound system in 3 + 1 dimensional QCD
Results in Physics, 2017 We investigate the Bethe-Salpeter-like amplitude in 3 + 1 dimensions. This involves a system comprising a quark and an antiquark combined by gauge fields to satisfy gauge invariance. We derive the equation of motion for this system and construct a series

PION–PION SCATTERING ABOVE RESONANCES [PDF]
Meson 2002, 2003 We model large angle intermediate energy pion-pion scattering by the pQCD two-gluon (2g) exchange contribution and discuss the onset of the dominance of the Glauber-Gribov-Landshoff (GGL) component. The pQCD 2g exchange contribution becomes substantial already at $|t|\sim$ 1 GeV^{2}, but the pQCD exchange dominance is deferred to $|t|\sim$ 3 GeV^{2 ...
