an extension of the Standard Model, rather than a replacement

Supersymmetry is an extension of the Standard Model, rather than a replacement.

all particles in our Standard Model

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 hopes to improve on the Standard Model

Supersymmetry is an idea that hopes to improve on the Standard Model, but the Standard Model has yet to make successful predictions about the Universe in attempting to supplant the prevailing theory.

an extension of the standard model ) (SMthat could describe the particle nature of DM in the form of the lightest neutralino in R-parity conserving models

Supersymmetry (SUSY) is an extension of the standard model (SM) that could describe the particle nature of DM in the form of the lightest neutralino in R-parity conserving models.

a symmetry principle that relates the properties of particles with a whole number amount (integer) of spin (bosons) to those with half a whole

Supersymmetry (a mathematical transformation) is a symmetry principle that relates the properties of particles with a whole number amount (integer) of spin (bosons) to those with half a whole

an extension of the Standard Model ) of particle physics (SMthat aims to fill gaps in SM by predicting a SUSY partner for each SM particle

Supersymmetry (SUSY) is an extension of the Standard Model (SM) of particle physics that aims to fill gaps in SM by predicting a SUSY partner for each SM particle.

an extension of the Standard Model ) (SMthat can resolve, for example, the gauge hierarchy problem by introducing supersymmetric partners of the known bosons and fermions

Supersymmetry (SUSY) is an extension of the Standard Model (SM) that can resolve, for example, the gauge hierarchy problem by introducing supersymmetric partners of the known bosons and fermions.

an extension of the Standard Model that offers an elegant solution to the hierarchy problem by fixing the mass of the Higgs boson

Supersymmetry is an extension of the Standard Model that offers an elegant solution to the hierarchy problem by fixing the mass of the Higgs boson.

an extension of the Standard Model in which every particle and anti-particle has a superpartner particle with a silly name, such as “gluinos” as the partners of gluons and “squarks” as the partners of quarks

Supersymmetry is an extension of the Standard Model in which every particle and anti-particle has a superpartner particle with a silly name, such as “gluinos” as the partners of gluons and “squarks” as the partners of quarks.

an extension of the standard model of physics that aims to fill in some big gaps regarding how scientists understand matter

Supersymmetry is an extension of the standard model of physics that aims to fill in some big gaps regarding how scientists understand matter.

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

What Incandela calls the “most complete and beautiful extension of the Standard Model” is a theory called supersymmetry, which can be represented in many different ways.

an extension of the Standard Model, which features a symmetry between matter and force and introduces many new particles, including possible candidates for dark matter

One of the possible theories is supersymmetry, an extension of the Standard Model, which features a symmetry between matter and force and introduces many new particles, including possible candidates for dark matter.

another possible “new physics” explanation

Supersymmetry is another possible “new physics” explanation.

a constraint that picks a subset of theories

Supersymmetry is a constraint that picks a subset of theories – ordinary theories with ordinary bosonic and fermionic fields that are just arranged (and whose interactions are arranged) so that there is an extra Grassmann-odd symmetry.

a colossal model that introduces new particles into the Standard Model’s equations

Supersymmetry (nicknamed SUSY for short) is a colossal model that introduces new particles into the Standard Model’s equations.

part of superstring theory, a string theory of quantum gravity

Supersymmetry is part of superstring theory, a string theory of quantum gravity, although quantum gravity could in theory be a component of other quantum gravity theories as well, such as loop quantum gravity.

a theory with no data, created to explain another theory with no data, which itself was created to explain a non-mechanical theory made up from whole cloth, again with no data and no possible data

Problem is, supersymmetry is a theory with no data, created to explain another theory with no data, which itself was created to explain a non-mechanical theory made up from whole cloth, again with no data and no possible data.

based on the theory of group transformations that was developed beginning in the early 1970s to understand at a more-fundamental level the burgeoning number of subatomic particles being produced in high-energy particle accelerator experiments

Supersymmetry is a complex mathematical framework based on the theory of group transformations that was developed beginning in the early 1970s to understand at a more-fundamental level the burgeoning number of subatomic particles being produced in high-energy particle accelerator experiments.

a theory that plugs many holes in the standard model

Supersymmetry is a theory that plugs many holes in the standard model by conjuring up a raft of heavier particles that partner each known particle.
