Supersymmetry is a theoretical framework in physics that suggests the existence of a symmetry between particles with integer spin (bosons) and particles with half-integer spin (fermions). It proposes that for every known particle, there exists a partner particle with different spin properties. [1] .

Mar 10, 2021 · At CMS, Long and other scientists hoped to find evidence for SUSY particles by examining signs of their decay as measured by an energy imbalance called missing transverse energy. When they examined the data, they found no signs of the expected energy imbalance from producing SUSY particles.

Oct 4, 2013 · Supersymmetry (SUSY) is one of the most loved, and most hated, theories around that works as an extension of our beloved Standard Model.

In theoretical physics, supersymmetric quantum mechanics is an area of research where supersymmetry are applied to the simpler setting of plain quantum mechanics, rather than quantum field theory.

May 16, 2012 · For SUSY, there are vast numbers of parameters to describe even the simplest SUSY extension of the SM, and it will never be possible to say “SUSY is ruled out at X confidence level”.

connected by long (dark) color strings; radiate (dark) glueballs and then annihilate at rest.

SUSY particles produced in the LHC are likely to be pairs of gluinos and/or squarks, heavy particles that will only live for 10 -23 seconds before they decay (turn into other more stable and familiar particles) in multiple stages, forming long “decay chains”.

• First 13 TeV results focus on strongly produced long-lived particles • Long-lived gluinos or squarks hadronize into “R-hadrons” • Experimentally relevant properties

Jul 11, 1997 · Projectors in the NS and R sectors are defined in the GS formalism. The consequences of supersymmetry are neatly derived at once for all massive states by factorising the character of the long SUSY multiplet.

May 20, 2019 · A theory that naturally motivates long-lived particles is supersymmetry (SUSY). A new search from the ATLAS Collaboration – released this week for the 5th International Conference on Particle Physics and Astrophysics (ICPPA-2020) – looks for the superpartners of the electron, muon and tau lepton.
