Interaction and Identification of the Di-Hadronic Molecules

Abstract

We study the interesting problem of interaction and identification of the hadronic molecules which seem to be deuteron-like structure. In particular, we propose a binding mechanism in which One Boson Exchange Potential plus Yukawa screen-like potential is applied in their relative s-wave state. We propose the dipole-like interaction between two color neutral states to form a hadronic molecule. For the identification of the hadronic molecules, the Weinberg's compositeness theorem is used to distinguish the molecule from confined (elementary) state. The present formalism predict some di-hadronic molecular states, involving quarks (s, c, b or s, c, b) as a constituents, namely, pn, KK, ρρwith their possible quantum numbers.

Masses of dibaryonic Ξ(∗)𝑐 Ξ(∗)𝑐 states

“…Certain multiquark states are hard to understand in terms of the standard quark model. The theoretical article proposes a number of potential exotic states including molecules, glueballs, hybrids, tetraquarks, pentaquarks, and hexaquarks [1][2][3][4][5][6][7][8][9][10][11]. Numerous exotic states, including XYZ, P c , Z(3900) + , and the double charm T ++ cc state, have been observed experimentally within the past years [12,13].…”

Spectroscopy of all charm tetraquark states

“…Y(4260), and Z(3931) [6][7][8][9]. The underlying structure of these exotic states necessitates a thorough investigation to exclude out molecular tetraquark state [10] or compact tetraquark as a viable explanation [11][12][13][14][15][16].…”
