Findings

Predicted masses of doubly charmed tetraquarks.

Predicted masses of doubly bottom tetraquarks.

Established mass hierarchy among these states.

Abstract

In this article, we perform a systematic study of the mass spectrum of the scalar doubly charmed and doubly bottom tetraquark states using the QCD sum rules.
