Dynamics of Symmetry Breaking and Tachyonic Preheating

Gary Felder, Juan Garcia-Bellido, Patrick B. Greene +3

We reconsider the old problem of the dynamics of spontaneous symmetry breaking using 3d lattice simulations, and develop a theory of tachyonic preheating, which occurs due to the s…

Expansion of bound-state energies in powers of m/M

Andrzej Czarnecki, Kirill Melnikov

We describe a new approach to computing energy levels of a non-relativistic bound-state of two constituents with masses M and m, by a systematic expansion in powers of m/M. After d…

Photoproduction of charm near threshold

S. J. Brodsky, E. Chudakov, P. Hoyer +1

Charm and bottom production near threshold is sensitive to the multi-quark, gluonic, and hidden-color correlations of hadronic and nuclear wavefunctions in QCD since all of the tar…

Semileptonic Form-factors from B-> K* gamma Decays in the Large Energy Limit

Gustavo Burdman, Gudrun Hiller

Making use of the measurement of the branching ratio together with the relations following from the limit of high recoil energy, we obtain stringent constraints on the…

Experimental Probes of the Randall-Sundrum Infinite Extra Dimension

Daniel J. H. Chung, Hooman Davoudiasl, Lisa Everett

The phenomenological possibilities of the Randall-Sundrum non-compact extra dimension scenario with the AdS horizon increased to approximately a millimeter length, corresponding to…

Light-Cone Wavefunction Representation of Deeply Virtual Compton Scattering

Stanley J. Brodsky, Markus Diehl, Dae Sung Hwang

We give a complete representation of virtual Compton scattering at large initial photon virtuality and small momentum transfer squared in terms of the ligh…
