“…Semi-leptonic decays of B-mesons have been studied by Bigi et al [6], Aliev et al [7], Hwang et al [8], and others. Recently, we studied the semi-leptonic decays of B-meson [9] in the framework of the ACCMM model and predicted the value of the Fermi momentum P F = 0.61 GeV for B-mesons, which extracts the value of | V ub V cb |= 0.2. The analysis shows that this value of | V ub V cb | yields a reasonable value of P F and a radius parameter for the B-meson.…”

The CP-violating ratio and the top-quark mass are estimated using the value of | v ub v cb | extracted in the framework of the Altarelli-Cabbibo-Corbo-Maiani-Martinelli model along with the statistical model. It has been suggested that Cabbibo-Kobyaschi-Masakawa matrix elements play an important role in determining the value of ; the enhanced value of can be obtained without lowering the strange-quark mass. The dependence of this important ratio on other parameters is also discussed with interesting conclusions.

The masses of the recently reported by LHCb two pentaquark charmonium states P * c (4380) and P * c (4450) which are supposed to have the configuration (uudcc) have been estimated in the framework of the quasiparticle model of diquarks considering [ud][uc]c configuration. The masses are reproduced very well which indicates that the description of diquark as quasiparticle is very useful for describing multiquark state and to understand the dynamics of it.

The properties of the proton has been investigated considering a proton as diquark-quark system. A model for diquark has been suggested in an analogy with the quasiparticle in a crystal lattice. The mass of the diquark obtained in the present model has been found to be in good agreement with other theoretical predictions. The binding energy of proton, compressibility and the excitation energy for the Roper Resonance have been estimated in the context of the proposed model. The results are found to be in agreement with the existing theoretical and experimental findings.The diquark is strongly correlated quark pair. It is now growing idea that the deeply bound diquarks are the building blocks of the mesons, baryon states and the exotics. The prediction of diquark is as old as the quark model and Gellmann has mentioned the possibility of diquark correlation in his original paper [1]. The regularities in the hadron spetroscopy, parton distribution functions, spin dependent structure function of hadrons etc. hints at the existence of diquark correlation [2][3][4][5][6]. At the experimental level it has been observed that the data for deep inelestic structure function for proton can be fitted in the frame work of the quark-diquark model of proton and it is predicted to be mostly in u [ud] state [7]. A number of works have been done towards the understanding of the structure of diquark. The possibility of forming quark-quark and quark-antiquark system by Instanton Induced Interaction (III) have been developed by Shuryak and Schafer et al. [8,9]. Betman et al. [10] have investigated formation of bound state of quark-quark or quark-antiquark systems due to instanton induced interaction and predicted that such bound state is formed inside the hadron as a bubble of the size of the instanton radius. In the context of discussing the exotic states of baryon Oka [11,12] has made a detailed study on the diquark correlation in the context of different models. It has been observed that the diquark picture in the framework of III model
