In this book, the authors present current advances in quarks research. Topics discussed in this compilation include the self-interaction mass formula relating all leptons and quarks to the electron; dirac model extension for finite size leptons and quarks in (10+1)D spacetime; quark confinement mechanisms for baryons; thermodynamical description of hadron-quark phase transition and its implications on compact-star phenomena; and the quark confinement analogy with baryonic bound states in superconductors.
