Mass spectra of dimesonic states in light flavour sector

Abstract

Masses of the dimesonic (meson-antimeson) molecular states are calculated using Yukawa like and meson exchange potential in semi-relativistic approach. The digamma decay width of the dimesonic systems are evaluated using the spectroscopic parameters. Many states such as f 0 ð980Þ, h 1 ð1380Þ, a 0 ð1450Þ, f 0 ð1500Þ, f 0 2 ð1525Þ, f 2 ð1565Þ, a 2 ð1700Þ, f 0 ð1710Þ, f 2 ð1810Þ, f 2 ð2010Þ have shown the signature of dimesonic molecules. Their masses and digamma widths are in good agreement with other theoretical results as well as experimental measurements.

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].…”

Interaction and Identification of the Meson-Baryon molecules

“…The interaction between tow color neutral states is largely unknown. The various interaction potentials have been used to explain such hadronic molecular structure [38][39][40][41][42][43]. The hdronic molecules should close to the s-wave.…”

Mass Spectra of Di-baronic Systems in Charm sector

“…Apart from deuteron, we are still searching other strong hadronic molecular candidate. There are large numbers of the hadronic molecules have been predicted in the various theoretical approaches in which H-dibaryon (in strange sector) is the most promising candidate with deep binding [1][2][3][4][5][6][7][8][9][10][11]. In this work, we have presented mass spectra of the possible Σ c − Σ c and Σ c − Σ c as di-hadron molecule.…”
