Vacuum energy and trace anomaly
Taekoon Lee
Concerning the trace anomaly in field theory a nonvanishing vacuum energy breaks the scale symmetry as well, in addition to the usual beta function dependent term, requiring a unit…
Bending of light in a Coulomb Gas
Taekoon Lee
Photons traveling in a background electromagnetic field may bend via the vacuum polarization effect with the background field. The bending in a Coulomb field by a heavy nucleus is…
Delbruck scattering in small scattering angle region
Taekoon Lee
The scattering of photons of x-ray energy off a Coulomb field in very forward scattering region may be thought as the refraction effect due to the Coulomb field. The cross section…
Extracting gluon condensate from the average plaquette
Taekoon Lee
The perturbative contribution in the average plaquette is subtracted using Borel summation and the remnant of the plaquette is shown to scale as a dim-4 condensate. A critical revi…
Flavor dependence of normalization constant for an infrared renormalon
Taekoon Lee
An ansatz is proposed for the flavor dependence of the normalization constant for the first IR renormalon in heavy quark pole mass.
Light bending in radiation background
Jin Young Kim, Taekoon Lee
We consider the velocity shift of light in presence of radiation emitted by a black body. Within geometric optics formalism we calculate the bending angle of a light ray when there…
