Operator renormalization group.
We introduce a novel operator renormalization group method. This is a new and more powerful variant of the t-expansion combining that method with the real space renormalization group approach. The aim is to extract infinite volume. physics at t + oo from calculations of only a few powers of t. Good results are obtained for the 1 + 1 dimensional Iking model. The method readily generalizes to hig...
متن کاملThe Trace Anomaly and the Parton Model
The trace anomaly is relevant to the renormalisation of the unpolarised parton distributions. The coefficient which describes the local γ∗(glue) interaction differs at next-to-leading order between the renormalised operator product expansion and parton model descriptions of deep inelastic scattering – independent of the factorisation scheme. There are two approaches to the theory of deep inelas...
متن کاملsaturation of the N = 4 monopole by infinite composite - operator renormalization
Quantum corrections to the magnetic central charge of the monopole in N = 4 supersymmetric Yang-Mills theory are free from the anomalous contributions that were crucial for BPS saturation of the two-dimensional supersymmetric kink and the N = 2 monopole. However these quantum corrections are nontrivial and they require infinite renormalization of the supersymmetry current, central charges, and ...
متن کاملQuantum Tunneling and Trace Anomaly
We compute the corrections, using the tunneling formalisim based on a quantum WKB approach, to the Hawking temperature and Bekenstein-Hawking entropy for the Schwarzschild black hole. The results are related to the trace anomaly and are shown to be equivalent to findings inferred from Hawking’s original calculation based on path integrals using zeta function regularization. Finally, exploiting ...
