Анотація

Оцiнюється вiдстань мiж частинками для пари кварк-антикварк з використанням потенцiалу конфайнмента та повного перерiзу розсiяння адронiв. Базуючись на вiльнiй енергiї Гельмгольца, розраховано ентропiю як функцiю потенцiалу конфайнмента бiля мiнiмуму повного перерiзу розсiяння. Виконано опис повного протон-протонного перерiзу розсiяння, де єдиним вiльним параметром моделi є масовий масштаб к, що визначає константу зв’язку для свiтлового фронту в КХД. Масштаб мас контролює вiдстань r для пари кварк-антикварк i допускає при деяких умовах появу вiльних кваркiв навiть у режимi КХД з конфайнментом.
