The QCD trace anomaly
QCD trace anomaly
2011/7/21
In this brief report we compare the predictions of a recent next-to-next-to-leading order hard-thermal-loop perturbation theory (HTLpt) calculation of the QCD trace anomaly to available lattice data. ...
On Third Order Lagrangians, Weyl Invariants & Classical Trace Anomaly in Six Dimensions
Higher Order Gravities Non–Linear Lagrangians Weyl Invariants Heat Kernel Coefficients Lovelock Lagrangian
2011/9/29
Abstract: We have proceeded the analogy of Einstein tensor and alternative form of Einstein field equations for generic coefficients of eight terms in third order of Lovelock Lagrangian. We have found...

gravitational inflaton decay gauge trace anomaly
2010/12/23
We analyze decay processes of the inflaton field, phi, during the coherent oscillation phase after inflation in f(phi)R gravity. It is inevitable that the inflaton decays gravitationally into gauge f...

Spontaneous Breaking of Conformal Invariance and Trace Anomaly Matching
Conformal Invariance Trace Anomaly Matching
2010/12/22
We argue that when conformal symmetry is spontaneously broken the trace anomalies in the broken and unbroken phases are matched. This puts strong constraints on the various couplings of the dilaton. U...
On the Trace Anomaly and the Energy-Momentum Conservation of Quantum Fields at D=2 in Classical Curved Backgrounds
the Energy-Momentum Conservation Quantum Fields Classical Curved Backgrounds
2010/10/21
We study the conformal symmetry and the energy-momentum conservation of scalar field interacting with a curved background at D = 2. We avoid to incorporate the metric determinant into the measure of t...
