Analytical solution of Balitsky-Kovchegov equation with homogeneous balance method

Analysis of hidden-charm pentaquark molecular states with and without strangeness via the QCD sum rules *

“…7 MeV, , ) have been well established [4]. As expected, , , , , and have been tentatively assigned to the , , , , and pentaquark molecular states, respectively, based on the contact-range effective field theory [5,6], one-boson exchange potential model [7][8][9], (quasipotential) Bethe-Salpeter equation [10][11][12][13], effective Lagrangian approach [14,15], effective-range expansion and resonance compositeness relation [16], Lippmann-Schwinger equation [17,18], and QCD sum rules [19][20][21][22][23].…”

“…At first glance, and , and it is unusual that the molecular state, which involves exchanges of strange mesons, is more tightly bound than the molecular state, which involves exchanges of non-strange mesons. Therefore, we have to introduce coupled-channel effects [7][8][9][10][11][12][13][16][17][18].…”

An analytical solution of Balitsky-Kovchegov equation using homotopy perturbation method

“…Analytical solutions to the BK equation proposed recently can be found with different approaches using some approximation in ref. [26][27][28][29][30][31]. These analytical solutions shed light on the ability of the BK equation in explaining gluon saturation and its application in the high energy hadron scattering phenomena.…”

Exclusive vector meson productions with the analytical solution of Balitsky-Kovchegov Equation

“…The analytical solution [55][56][57][58][59] of BK equation has been studied by different methods. We also obtain the analytical solution of BK equation [60] in the momentum space. In this work, the analytical solution that we have obtained will be used to explain the scattering process between protons and color dipole.…”
