Testing Lorentz invariance by use of vacuum and matter filled cavity resonators

Holger Mueller

We consider tests of Lorentz invariance for the photon and fermion sector that use vacuum and matter-filled cavities. Assumptions on the wave-function of the electrons in crystals…

Exclusive Decuplet-Baryon Pair Production in Two-Photon Collisions

Carola F. Berger, Wolfgang Schweiger

This work extends our previous studies of two-photon annihilation into baryon-antibaryon pairs from spin-1/2 octet to spin-3/2 decuplet baryons. Our approach is based on perturbati…

New Results in Light-Front Phenomenology

S. J. Brodsky

The light-front quantization of gauge theories such as QCD in light-cone gauge provides a frame-independent wavefunction representation of relativistic bound states, simple forms f…

Kaluza-Klein Dark Matter, Electrons and Gamma Ray Telescopes

Edward A. Baltz, Dan Hooper

Kaluza-Klein dark matter particles can annihilate efficiently into electron-positron pairs, providing a discrete feature (a sharp edge) in the cosmic spectrum at an energ…

Novel Aspects of QCD in Leptoproduction

S. J. Brodsky

I review several topics in electroproduction which test fundamental aspects of QCD. These include the role of final-state interactions in producing diffractive leptoproduction proc…

Novel QCD Aspects of Hard Diffraction, Antishadowing, and Single-Spin Asymmetries

S. J. Brodsky

It is usually assumed -- following the parton model -- that the leading-twist structure functions measured in deep inelastic lepton-proton scattering are simply the probability dis…
