Pion Detection Using Single Photon Avalanche Diodes [PDF]
Sensors, 2023 We present the first reported use of a CMOS-compatible single photon avalanche diode (SPAD) array for the detection of high-energy charged particles, specifically pions, using the Super Proton Synchrotron at CERN, the European Organization for Nuclear ...

Regge analysis of pion-pion (and pion-kaon) scattering for energy s^{1/2}>1.4 GeV [PDF]
Phys.Rev.D69:114001,2004, 2003 We perform a detailed Regge analysis of NN, pion-N and pion-pion scattering. From it, we find expressions that represent the pion-pion scattering amplitudes with an accuracy of a few percent, for exchange of isospin zero, and $\sim15%$ for exchange of isospin 1, and this for energies s^{1/2}> 1.4 GeV and for momentum transfers |t|^{1/2}< 0.4 GeV ...

Evaluation of the Axial Vector Commutator Sum Rule for Pion-Pion Scattering [PDF]
Phys.Rev.D75:116002,2007, 2007 We consider the sum rule proposed by one of us (SLA), obtained by taking the expectation value of an axial vector commutator in a state with one pion. The sum rule relates the pion decay constant to integrals of pion-pion cross sections, with one pion off the mass shell.

Information on the structure of the rho meson from the pion form-factor [PDF]
Phys.Rev.D80:114012,2009, 2009 The electromagnetic pion form-factor is calculated in a Bethe-Salpeter approach which accounts for pion rescattering. In the scattering kernel the pion-pion contact interaction from lowest-order chiral perturbation theory is considered together with an optional vector meson in the s-channel.

The pion charge radius from charged pion electroproduction [PDF]
Phys.Rev. C62 (2000) 028201, 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 longitudinal dipole amplitude $L_{0+}^{(-)}$.

The pion-pion scattering amplitude [PDF]
Physical Review D, 2004 We obtain reliable $\pi\pi$ 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 ($s^{1/2}\leq1.42 {\rm GeV}$) phase

Pion-pion and pion-nucleon interactions in chiral perturbation theory [PDF]
, 1997 Elastic pion-pion and pion-nucleon scattering are reviewed in the context of chiral perturbation theory. Theoretical results from systematic low-energy expansions to O(p^6) for pion-pion and to O(p^3) for pion-nucleon scattering are compared with experimental data. Possible future developments are outlined.

Universe, 2023 The analysis of the spatiotemporal picture of particle radiation in relativistic heavy-ion collisions in terms of correlation femtoscopy scales, emission, and source functions allows one to probe the character of the evolution of the system created in ...

Study of Pion-Pion Interactions From Pion Production by Pions [PDF]
Physical Review Letters, 1962 Reactions pi /sup plus or minus / + p yields pi /sup plus or minus / + pi /sup +/ + n were studied at a n incident pion momentum of 1.75 Bev/c. The experimental apparatus and procedure are described in detail, and the measured and calculated data are presented and discussed. Evidence was found of a pion-pion interaction in the ( pi /sup +/- pi /sup -/)
