Supersymmetry is one of the most motivated Standard Model extensions.

a conjectured relationship between two basic classes of elementary particles: bosons, which have an integer-valued spin, and fermions, which have a half-integer spin

In particle physics, supersymmetry (SUSY) is a conjectured relationship between two basic classes of elementary particles: bosons, which have an integer-valued spin, and fermions, which have a half-integer spin.

the front-runner for theories beyond the Standard Model

As yet, supersymmetry is still the front-runner for theories beyond the Standard Model and most physicists remain optimistic for most physicists's prospects.

a symmetry that connects fermions and bosons - into the Standard Model

This heavily- studied model is the minimal phenomenologically viable incorporation of supersymmetry - a symmetry that connects fermions and bosons - into the Standard Model.

a theory in which all particles in our Standard Model – electrons, protons, neutrons, and so on – have a more massive 'supersymmetric' partner

Supersymmetry is a theory in which all particles in our Standard Model – electrons, protons, neutrons, and so on – have a more massive 'supersymmetric' partner.

an idea that connects particles of different spins

Supersymmetry is an idea that connects particles of different spins: different spins says they are different aspects of the same underlying object.
