Nucleon-Antinucleon Interaction from the Skyrme Model: II. Beyond the Product Ansatz
Yang Lu, Pavlos Protopapas, R. D. Amado
We calculate the full static interaction of a Skyrmion and an anti-Skyrmion as a function of separation and relative grooming. From this, using projection methods and Born-Oppenhei…
Nucleon-Antinucleon Interaction from the Skyrme Model
Yang Lu, R. D. Amado
We calculate the nucleon-antinucleon static potential in the Skyrme model using the product ansatz and including some finite (number of colors) corrections. The mid and long…
On the relationship of the scaled phase space and Skyrme-coherent state treatments of proton antiproton annihilation at rest
R. D. Amado, F. Cannata, J-P. Dedonder +3
We discuss pion multiplicities and single pion momentum spectra from proton antiproton annihilation at rest. Both the scaled phase space model and the Skyrme-coherent state approac…
Pion correlation from Skyrmion-AntiSkyrmion annihilation
Yang Lu, R. D. Amado
We study two pion correlations from Skyrmion and antiSkyrmion collision, using the product ansatz and an approximate random grooming method for nucleon projection. The spatial-isos…
Nucleon-Antinucleon Annihilation in Large Nc QCD with rho and omega Mesons
Yang Lu, R. D. Amado
We use classical/large Nc (number of colors) QCD to study nucleon--antinucleon annihilation at rest. We include pion, rho and omega fields in the classical dynamics, starting from…
Branching Ratios in Proton Antiproton Annihilation at Rest from Large Nc QCD
Yang Lu, R. D. Amado
We use classical or large Nc QCD to describe the mesons (pion, rho, omega) coming from proton-antiproton annihilation at rest as classical fields, which we then quantize as coheren…
