Skyrmion-anti-Skyrmion Annihilation with Omega Mesons
M. A. Halasz, R. D. Amado
We study numerically the annihilation of an omega-stabilized Skyrmion and an anti-Skyrmion in three spatial dimensions. To our knowledge this is a first successful simulation of Sk…
Two Skyrmion Dynamics with Omega Mesons
R. D. Amado, M. A. Halasz, P. Protopapas
We present our first results of numerical simulations of two skyrmion dynamics using an -meson stabilized effective Lagrangian. We consider skyrmion-skyrmion scattering with a f…
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…
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…
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…
Dynamics of antibaryon-baryon annihilation in the Skyrme model
Bin Shao, Niels R. Walet, R. D. Amado
We examine the dynamics of a baryon number zero lump in the Skyrme picture, as a model for annihilation in the system. We find that radiation propagates at the causal li…
