“…We incorporated this additional information. To estimate the pressure distribution, we employed a temperature profile dependent on the radius, as discussed in [ 41 ]. The authors assumed that the bag pressure could vary within a small range with volume and, consequently, it may change with radius.…”

“…For this purpose, we have determined that a suitable approximation for the bag pressure is an exponential of the form:

MeV This expression aligns with the middle ground between the two curves shown in Figure 1 . To derive this expression, we utilized data from the two models considered in [ 41 ]. In Figure 1 , we compare the exponential bag pressure used with the scenarios presented in [ 41 ].…”

We present a phenomenological framework based on the MIT bag model to estimate the pressure experienced by quarks and gluons inside nucleons. This is accomplished by implementing non-extensive Tsallis statistics for the two-component system. In this model of hadrons, the strong interaction generates correlations effectively described by the q-Tsallis parameter. The resulting hadron pressure exhibits general agreement with recent calculations derived from Lattice QCD. Additionally, we compared this pressure with data extracted from deep virtual Compton scattering experiments and gravitational form factor analyses. The extended bag model provides an alternative interpretation of bag pressure in terms of the q-Tsallis parameter. Consequently, the MIT bag model can be expressed without requiring the inclusion of the bag pressure parameter.

“…A proton is composed of three quarks [1][2][3][4][5][6][7], and its mass has been measured with good accuracy but cannot be predicted theoretically using analytic solutions. Numerical calculations for determining the proton mass are well known in quantum chromodynamics (QCD), where the mass of hadrons can be calculated using a supercomputer [8][9][10][11][12]. The QCD model is described by the SU(3) and Yang-Mills fields [13][14][15].…”

In this study, we describe quark confinement in terms of linear interaction potentials and solve the problem of the net spin of a proton. The three quarks in a proton are assumed to revolve around a common center, and their masses are determined assuming they are Dirac particles. On the basis of these assumptions, the magnetic moment of a proton can be derived. Moreover, the rotation of the quarks is considered, in which an electrical current induces a magnetic field. Thus, the scalar product of the magnetic moment and field describes the linear interaction potential between the quarks, and the mass of the proton can be obtained. The proton mass predicted by this physical model is consistent with experimental values, and no numerical or fitting calculations are required. Furthermore, using the newly derived spins and angular momentum of the three quarks, we derived the net spin of a proton. Additionally, we predicted the mass of a pi-meson from the same model, which agrees with the experimental values.

This study describes quark confinement in terms of linear interaction potentials. The three quarks in a proton are assumed to revolve around a common center and have masses determined as if they were Dirac particles. Under these assumptions, the magnetic moment of a proton is derived via Maxwell’s equations. Moreover, the rotational motion of the quarks can be thought of as an electrical current that induces a magnetic field. Thus, the scalar product of the magnetic moment and the magnetic field describes a linear interaction potential between the quarks that gives the mass of the proton. The proton mass as predicted by this physical model is in good agreement with experimental observations and requires no numerical calculations. Thus, the simple physical model suggests a solution for the problem of quark confinement by modeling the strong force as an interaction potential.
