It is then possible to trace the transition to the deconfined phase or the appearence of a mixed phase. We present recent results on the structure of neutron stars based on this procedure. For the nucleon matter, the microscopic many-body theory of the Nuclear Equation of State is discussed...
Generally speaking, conventional neutron stars and non-mainstream quark stars are two types of models to describe the inner structure of pulsars, with the former composed mainly of hadrons and the latter of a peculiar kind of matter whose state equation should be understood in the level of ...
speed of soundcsin strongly interacting matter. If the conformal boundcs2≤1/3(ref.7) is not strongly violated, massive neutron stars are predicted to have sizable quark-matter cores. This finding has important implications for the phenomenology of neutron stars and affects the dynamics of ...
Structural view of a proton with two up quarks (blue and red) and one down quark (green) and a neutron with one up quark (green) and two down quarks (red and blue).The forces between quarks are mediated by gluons. The proton is a subatomic particle with a positive electric charge of...
physics of elementary particles and fieldsUsing the recently published data from the BONuS (Barely Off-shell Nucleon Structure) experiment at Jefferson Lab, which utilized a spectator tagging technique to extract the inclusive electron-free neutron scattering cross section, we obtain the first direct ...
The isotopic symmetry (symmetry with respect to the T3→– T3 operation) states that in the neutron, u(x) refers to d-quarks, d(x) to u-quarks, s(x) to s-quarks, and u¯(x), d¯(x), s¯(x) to d¯, u¯, and s¯-quarks, respectively. A number of sets of ...
1 up quark and 2 down quarks make a neutron. What are the 6 types of quarks? There are six different flavors of quarks: up quarks, down quarks, strange quarks, charmed quarks, top quarks, and bottom quarks. Each of these quarks varies in its mass, and its fractional charges....
The effect of nucleon's possible quark-diquark structure is added to the usual constituent quark model to calculate nucleon's charge root-mean-square radius. The experimental values of both <r 2pc >1/2=(0.88±0.03) fm for a proton and <r 2nc >1/2=(−0.12±0.01) fm2 for a neutro...
