The past decades witnessed the golden era of hadron physics. Many excited open heavy
flavor mesons and baryons have been observed since 2017. We shall provide an updated …

A coupled channel analysis of the D⁎+ D 0 and D⁎ 0 D+ system is performed to study the
doubly charmed T c c+ state recently discovered by the LHCb collaboration. We use a …

Energy spectrum of doubly heavy tetraquarks, TQQ (QQ q¯ q¯ with Q= c, b and q= u, d, s), is
studied in the potential chiral-diquark model. Using the chiral effective theory of diquarks …

We perform a fit to the LHCb data on the T cc (3875) state in order to determine its nature.
We use a general framework that allows to have the D 0 D∗+, D+ D∗ 0 components forming …

In this work, we study the reaction of a nucleon and a doubly charmed state\(T^+ _ {cc}\).
Under the assumption of the\(T^+ _ {cc}\) as a molecular state of\(D^{*} D\), the reaction of …

We present mass spectrum and magnetic moments of the n¯ n¯ QQ states, where n= u, d, s
and Q= c, b. We solve four-body Schrödinger equation with a quark potential model by using …

Abstract The\(\Sigma _ {c}(2800)^+\) and\(\Lambda _c (2940)^+\) states are among the most
interesting and intriguing particles whose internal structures have not yet been elucidated …

Inspired by the detection of T cc tetraquark state by LHCb Collaboration, we perform a
systemical investigation of the low-lying doubly heavy charm tetraquark states with …

Treating X (4140) as a compact JPC= 1++ csc¯ s¯ state and using its mass as a reference
scale, we systematically estimate the masses of doubly heavy tetraquark states QQ q¯ q¯ …

In this work, we discuss the electromagnetic properties of the S-wave and D-wave T cc+
molecular states, which include the magnetic moments, transition magnetic moments, and …
