В настоящем исследовании влияние топологического дефекта на масс-спектры тяжелых и тяжелых-легких мезонов, таких как чармоний, боттомоний и шарм-стрэндж, боттом-чарм, соответственно, изучается с помощью потенциала Хюльтена плюс Юкавы. Уравнение Шрёдингера решается аналитически методом Никифорова-Уварова. Получены приближенные решения энергетического спектра и ненормированной волновой функции. Полученные результаты применены для предсказания масс-спектров тяжелых и тяжело-легких мезонов при наличии и отсутствии топологического дефекта для различных квантовых состояний. Установлено, что при увеличении топологического дефекта масс-спектры смещаются и ихзначения приближаются к экспериментальным данным. Однако, по сравнению с работой других исследователей, результаты показали улучшенное решение для описания масс-спектров.
