	Supersymmetry - Wikipedia, the free encyclopedia
		Supersymmetry was originally proposed in 1973 by Julius Wess and Bruno Zumino.
		Supersymmetries, on the other hand, are generated by objects that transform under the spinor representations.
		The standard paradigm for incorporating supersymmetry into a realistic theory is to have the underlying dynamics of the theory be supersymmetric, but the ground state of the theory does not respect the symmetry and supersymmetry is broken spontaneously.

		Supersymmetry provides a possible mechanism for understanding the large hierarchy in scale between the masses of particles studied with accelerators and the “natural” scale of physics which is the Planck mass.
		I am studying effective supergravity theories for particle physics, with the goal of addressing the problems of supersymmetry breaking and electroweak symmetry breaking, as well as other aspects of particle physics and cosmology, in the context of superstring theory.
		A promising mechanism for supersymmetry breaking is a phenomenon called “condensation” that is known to play an important role in quantum chromodynamics, the theory of strong interactions in the Standard Model.

	mssm
		The different supersymmetry breaking mechanisms can be characterized by the mass of the messenger which couples the supersymmetry breaking sector to the visible sector.
		In this class of supersymmetry breaking the lightest supersymmetric particle is a combination of a neutralino and Higgsino.
		A second possibility is that the messenger is a gauge non-singlet field coupling the supersymmetry breaking sector to the visible sector.

	Jonathan A. Bagger: Research Activities
		We study in some detail the spectral phenomenology of models in which supersymmetry is dynamically broken and transmitted to the supersymmetric partners of the quarks, leptons and gauge bosons, and the Higgs bosons themselves, via the usual gauge interactions.
		The partial spontaneous breaking of rigid N=2 supersymmetry implies the existence of a massless N=1 Goldstone multiplet.
		All generic, calculable models of dynamical supersymmetry breaking have a spontaneously broken R symmetry and therefore contain an R axion.

	Introduction to Supersymmetry (Site not responding. Last check: 2007-09-17)
		Supersymmetry is an idea that history repeats itself to solve similar problems.
		Supersymmetry actually makes the unification of three other forces, strong, weak, and electromagnetic, also a reality.
		In (a), in the Standard Model without supersymmetry, the strengths of three forces change as a function of energies, and become closer to each other at very high energies.

	Electroweak breaking and supersymmetry breaking (Site not responding. Last check: 2007-09-17)
		We discuss the clash between the absence of fine tuning in the Higgs potential and a sufficient suppression of flavour changing neutral current transitions in supersymmetric extensions of the standard model.
		It is pointed out that horizontal $U(1)$ symmetry combined with the $D$-term supersymmetry breaking provides a realistic framework for solving both problems.

	Supersymmetry
		Supersymmetry is an attractive extension of Standard Model which could provide a solution to the hierarchy problem.
		Supersymmetry can not be an exact symmetry of nature (else squarks and quarks would have the same mass !) Hence it has to be broken.
		Therefore, the terms you can add should not break susy too strongly, in the sense that they should not bring quadratic divergences.

	Supersymmetry breaking - Wikipedia, the free encyclopedia
		In particle physics, supersymmetry breaking is the process to obtain a seemingly non-supersymmetric physics from a supersymmetric theory which is a necessary step to reconcile supersymmetry with actual experiments.
		It is an example of spontaneous symmetry breaking.
		The superpartners whose mass would otherwise be equal to the mass of the regular particles in the absence of the SUSY breaking become much heavier.

	[No title]
		Supersymmetry is also an integral element in attempts to unify the theories of particle physics, both if one considers the unification of Standard Model gauge couplings and if one wishesto unify all the forces of Nature, including gravity, as an essential ingredient of superstring models.
		Many supersymmetric models either allow explicit R-parity breaking or it is spontaneously broken in the model.
		Another important topic in the supersymmetric theories is the method of supersymmetry breaking.

	Supersymmetry breaking in warped geometry
		We examine the soft supersymmetry breaking parameters in supersymmetric theories on a slice of
		In such models, if supersymmetry breaking is mediated by the bulk radion superfield and/or some brane chiral superfields, potentially dangerous flavor-violating soft parameters are suppressed with an appropriate correlation with the Yukawa coupling suppression, thereby avoiding the SUSY flavor problem in a natural manner.
		We present some models of radion-dominated supersymmetry breaking which yield a highly predictive form of soft parameters in this framework, and discuss the constraints from flavor-changing rare processes.

		We study under which circumstances Supersymmetry is "persistent".
