Chiral Symmetries and Low Energy Searches for New Physics
نویسنده
چکیده
The search for physics beyond the Standard Model (BSM) lies at the forefront of the intersection of nuclear physics with particle physics and cosmology. In this talk, I attempt to give an overview of low-energy studies that are being used in this search and try to describe ways in which they complement present and future high energy collider studies. As theme for this meeting is the broken chiral symmetry of QCD, I will endeavor to highlight the role played by chiral symmetries in both the low energy BSM searches and various BSM scenarios. In particular, I will address four questions:

Fundamental Symmetries and Interactions - Some Aspects
In the framework of nuclear physics and at nuclear physics facilities a large number of different experiments can be performed which render the possibility to investigate fundamental symmetries and interactions in nature. In particular, the precise measurements of properties of fundamental fermions, searches for new interactions in β-decays, and violations of discrete symmetries have a robust d...
متن کاملNeutrons and the New Standard Model
Fundamental symmetry tests with neutrons can provide unique information about whatever will be the new Standard Model of fundamental interactions. I review two aspects of this possibility: searches for the permanent electric dipole moment of the neutron and its relation to the origin of baryonic matter, and precision studies of neutron decay that can probe new symmetries. I discuss the compleme...
متن کاملFundamental Symmetries and Interactions
In nuclear physics numerous possibilities exist to investigate fundamental symmetries and interactions. In particular, the precise measurements of properties of fundamental fermions, searches for new interactions in β-decays, and violations of discrete symmeties offer possibilities to search for physics beyond standard theory. Precise measurements of fundamental constants can be carried out. Lo...
متن کاملPrecision Bounds on Flavor Gauge Bosons
Gauged flavor symmetries at low energies have been proposed in models of dynamical electroweak symmetry breaking and fermion mass generation. The massive flavor gauge bosons give rise to corrections to precisely measured electroweak quantities. We perform a fit to the Z-pole electroweak data and place indirect limits on such new physics. In particular we study several models from the literature...
متن کاملChiral Dynamics beyond the Standard Model
A systematic search of Physics beyond the Standard Model is usually formulated in the framework of a Low-Energy Effective theory (LEET). One expects that at very high energies E > Λ there exist new (gauge) particles and that their interaction is governed by new (local) symmetries not contained in the SM gauge group SU(2)W × U(1)Y . In order to specify the LEET which would describe the Physics b...
