Vector Mesons and Dense Skyrmion Matter
In our continuing effort to understand hadronic matter at high density, we have developed a unified field theoretic formalism for dense skyrmion matter using a single Lagrangian to describe simultaneously both matter and meson fluctuations and studied in-medium properties of hadrons. Dropping the quartic Skyrme term , we incorporate into our previous Lagrangian the vector mesons ρ and ω in a fo...
متن کاملSliding Vacua in Dense Skyrmion Matter
In continuation of our systematic effort to understand hadronic matter at high density, we study dense skyrmion matter and its chiral phase structure in an effective field theory implemented with the trace anomaly of QCD applicable in the large N c limit. By incorporating a dilaton field χ associated with broken conformal symmetry of QCD into the simplest form of skyrmion Lagrangian, we simulat...
متن کاملNeutral pion decay into in dense Skyrmion matter
Neutrinos and their means of production play an important role in cosmological and astrophysical phenomena [1]. In particular in this paper we shall be concerned with the weak emission of a neutrino-antineutrino pair from a neutral pion, 0 ! , which figures centrally in the pionpole mechanism [2,3] for the process ! 0 ! relevant to the neutrino emission process ! . The latter has been suggested...
متن کاملThe Role of the Dilaton in Dense Skyrmion Matter
In this note, we report on a remarkable and surprising interplay between the ω meson and the dilaton χ in the structure of a single skyrmion as well as in the phase structure of dense skyrmion matter which may have a potentially important consequence on the properties of compact stars. In our continuing effort to understand hadronic matter at high density, we have developed a unified field theo...
متن کاملAtiyah-Manton Approach to Skyrmion Matter
We propose how to approach, and report on the first results in our effort for, describing nuclear matter starting from the solitonic picture of baryons which is supposed to represent QCD for large number of colors. For this purpose, the instanton-skyrmion connection of Atiyah and Manton is exploited to describe skyrmion matter. We first modify ’t Hooft’s multi-instanton solution so as to suitab...
