Electromagnetic Mass Anomaly ∗
Electromagnetic masses of neutral K * (892) may be larger than one of charged K * (892). It is unusual and is called K *-EM-mass anomaly. We review the studies on this issue, and point out that K *-mass splitting can be measured in BES accurately.
متن کاملConformal anomaly for dilaton coupled electromagnetic field
The derivation of the conformal anomaly for dilaton coupled electromagnetic field in curved space is presented. The models of this sort naturally appear in stringy gravity or after spherical reduction of multidimensional Einstein-Maxwell theory. It is shown that unlike the case of minimal vector in curved space or dilaton coupled scalar the anomaly induced effective action cannot be derived. Th...
متن کاملElectromagnetic Corrections in the Anomaly Sector
Chiral perturbation theory in the anomaly sector for Nf = 2 is extended to include dynamical photons, thereby allowing a complete treatment of isospin breaking. A minimal set of independent chiral lagrangian terms is determined and the divergence structure is worked out. There are contributions from irreducible and also from reducible one-loop graphs, a feature of ChPT at order larger than four...
متن کاملPossible model of electromagnetic signals before
Few days before many earthquakes a general change in the ratio of vertical to horizontal magnetic field components in the ULF band, often called “polarization”, has been observed that can be considered as a magnetic precursor of the subsequent earthquake. To explain such a specific behavior, we propose a simple model based on a linear current approximation depending on some assumption on the si...
متن کاملElectromagnetic Signatures of the Chiral Anomaly in Weyl Semimetals.
Weyl semimetals are predicted to realize the three-dimensional axial anomaly first discussed in particle physics. The anomaly leads to unusual transport phenomena such as the chiral magnetic effect in which an applied magnetic field induces a current parallel to the field. Here we investigate diagnostics of the axial anomaly based on the fundamental equations of axion electrodynamics. We find t...
