SUMMARY

Resonances in physics refer to particles or particle systems that exist in an excited and unstable energy state. Key examples include baryonic resonances such as Lambda, Sigma, Delta, Xi, and Omega particles. Additionally, nuclear resonances are significant in the context of neutron absorption cross-sections. Understanding these concepts is crucial for grasping the behavior of particles in quantum mechanics.

PREREQUISITES
  • Basic understanding of quantum mechanics
  • Familiarity with particle physics terminology
  • Knowledge of baryons and their classifications
  • Understanding of neutron absorption and cross-section concepts
NEXT STEPS
  • Research baryonic resonances in detail, focusing on Lambda and Sigma particles
  • Study the implications of nuclear resonances on neutron absorption cross-sections
  • Explore the role of resonances in quantum mechanics through academic papers
  • Examine experimental methods for detecting resonances in particle physics
USEFUL FOR

Students and researchers in physics, particularly those specializing in particle physics and quantum mechanics, will benefit from this discussion on resonances.

what exactly are resonances? are they particles, energy,..?

In what context?

A reasonable description would be particles or particle systems in an excited (unstable) energy state.

http://en.wikipedia.org/wiki/Resonance#Resonances_in_quantum_mechanics

One can think of baryonic resonances - Lambda, Sigma, Delta, Xi, Omega particles - http://hyperphysics.phy-astr.gsu.edu/hbase/particles/baryon.html
http://en.wikipedia.org/wiki/List_of_baryons

Or nuclear resonances with respect to neutron absorption cross-seciton.
