Description

A simple semi-empirical equation of state is developed for cold hadronic matter composed of light quarks of two flavours. The source of binding energy in the model is the decreasing asymmetry between the number of up and down quarks. The resulting incompressibility of symmetric nuclear matter is 324 MeV. The incompressibility decreases rapidly with decreasing density but increases only slowly with increasing density

Abstract (Russian)

Развито простое полуэмпирическое уравнение состояния для холодной адронной материи, состоящей из легких кварков двух запахов. Источником энергии связи в этой модели является уменьшение асимметрии между числом верхних и нижних кварков. В результате несжимаемость симметричной ядерной материи составляет 324 МэВ. Она быстро уменьшается с уменьшением плотности и медленно увеличивается с ее увеличением
