Measurement of the γ3π process has revealed a possible conflict with what should be a solid prediction generated by the chiral anomaly. We show that inclusion of appropriate energy-momentum dependence...
Product Einstein Manifolds, Zeta-Function Regularization and the Multiplicative Anomaly
Addition multiplication Laplace symmetric Spaces the product space
2014/12/22
The global additive and multiplicative properties of Laplace type operators acting on irreducible rank 1 symmetric spaces are considered. The explicit form of the zeta function on product spaces and o...
Chiral anomaly and eta-eta ' mixing
Octet singlet pseudoscalar decay constant mixing Angle
2014/12/22
We determine the η-η′ mixing angle via a procedure relatively independent of theoretical assumptions by simultaneously fitting η,η′ reactions involving the anomaly η,η′→γγ, π+π-γ. We extract reasonabl...
Relativistic Cosmology and the Pioneers Anomaly
Relativistic Cosmology the Pioneers Anomaly
2011/9/6
NASA spacecrafts has suffered from three anomalies. The Pioneers spacecrafts were decelerated,and their spin when not disturbed, was declining. On the other hand, fly-bys for gravity assists,appeared ...
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...
On the rate of gravitational inflaton decay via gauge trace anomaly
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...
Hypercharge Flux, Exotics, and Anomaly Cancellation in F-theory GUTs
Hypercharge Flux Exotics Anomaly Cancellation in F-theory GUTs
2010/12/23
We sharpen constraints related to hypercharge flux in F-theory GUTs that possess U(1) symmetries and argue that they arise as a consequence of 4-dimensional anomaly cancellation. This gives a physical...
Exact solution for eigenfunction statistics at the center-of-band anomaly in the Anderson localization model
Exact solution for eigenfunction statistics Anderson localization model
2010/11/24
An exact solution is found for the problem of the center-of-band (E = 0) anomaly in the one-
dimensional (1D) Anderson model of localization. By deriving and solving an equation for the
generating f...

Proton size anomaly
2010/12/29
A measurement of the Lamb shift in muonic hydrogen yields a charge radius of the proton that is smaller than the CODATA value by about 5 standard deviations. We explore the possibility that new scalar...

To one loop order, interacting boson fields on de Sitter space have an “infrared” anomaly that breaks the de Sitter symmetry for all vacua save the Euclidian one. The divergence of a symmetry current ...

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...
