Long-time asymptotic behavior for the nonlocal nonlinear Schro¨dinger equation in the solitonic region

引用

Science China Mathematics 2024年

作者： Gaozhan Li yiling Yang engui Fan School of Mathematical Sciences and Key Laboratory of Mathematics for Nonlinear Sciences Fudan University

In this paper, we extend the ■-steepest descent method to study the Cauchy problem for the nonlocal nonlinear Schr?dinger（NNLS） equation with weighted Sobolev initial data iqt+qxx+2σ■2（x, t）q（-x, t） = 0,q（x, 0） = q0（x）,where q0∈ H1,1（R）. Based on the spectral analysis of the Lax pair, the solution of the Cauchy problem is expressed in terms of the solution of a Riemann-Hilbert problem, which is transformed into a solvable model after a series of deformations. We further obtain the asymptotic expansion of the solution to the Cauchy problem for the NNLS equation in the solitonic region. The leading term is soliton solutions, the second term is the interaction between solitons and dispersion, and the error term comes from a corresponding?ˉ-*** with the asymptotic results on the classical NLS equation, the major difference is the second and third terms of the asymptotic expansion for the NNLS equation, which were affected by a function depending on the scattering data and the stationary phase point.

作者：谢易凌孙昊 Institute of Theoretical Physics School of PhysicsDalian University of TechnologyNo.2 Linggong RoadDalian 116024China

In this study,we assign the tetraquark state for the Y(4230) resonance and investigate the mass and decay constant of Y(4230) in the framework of SVZ sum rules through a different calculation ***,we calculate the strong coupling gYJ/ψf0 by considering soft-meson approximation techniques within the framework of light cone sum rules,and we use the strong coupling gYJ/ψf0 to obtain the width of the decay Y(4230)→J/ψf0(980).Our prediction for the mass agrees with the experimental measurement,and that for the decay width of Y(4230)→J/ψf0(980) is within the upper limit.
