An explanation of 3D structure of neutrons and protons using string theory

In string theory, all the elementary particles are different modes of the vibrating strings of Planck size. We have closed strings for fermions and open strings for bosons in superstring theory in 10 dimensions. The strings can expand and contract minimum upto Planck length since the length smaller than Planck length is meaningless. The total energy of protons and neutrons as well as mass spectrum corresponding to Neumann and Dirichlet strings can help us in determining the 3D structure of neutrons and protons. Since total energy is constant and there is stretching of the strings during the transition in the shape of the gravitational space-time and strong nuclear force within protons and neutrons in QCD-gravity duality. The size of the interacting strings in QCD-gravity duality can expand upto the size of the protons and neutrons in Dp brane in order to acquire the tension in the string as described by equation. Finally, we have come to the conclusion that String of Planck length size can be expanded upto size of neutrons and protons in higher dimensional space i.e. for D=5-10. During interaction between three closed strings. Thus the 3D structure of neutrons and protons can be determined using QCD-gravity duality in string theory
