Form factors of the -meson in chiral perturbation theory
Kakha Shamanauri, Jambul Gegelia, Ulf-G. Meißner +1
We present the calculation of the electromagnetic form factors of the -meson at one loop in Chiral Perturbation Theory. The power-counting-violating terms in the loop diagrams a…
A bound on the nucleon Druck-term from chiral EFT in curved space-time and mechanical stability conditions
Jambul Gegelia, Maxim V. Polyakov
Using dispersive representations of the nucleon gravitational form factors, the results for their absorptive parts from chiral effective field theory in curved space-time, and the…
Form factors in lattice QCD
B. B. Brandt, S. Capitani, M. Della Morte +7
Lattice simulations of QCD have produced precise estimates for the masses of the lowest-lying hadrons which show excellent agreement with experiment. By contrast, lattice results f…
Path integral quantization for massive vector bosons
D. Djukanovic, J. Gegelia, S. Scherer
A parity-conserving and Lorentz-invariant effective field theory of self-interacting massive vector fields is considered. For the interaction terms with dimensionless coupling cons…
Infrared renormalization of two-loop integrals and the chiral expansion of the nucleon mass
M. R. Schindler, D. Djukanovic, J. Gegelia +1
We describe details of the renormalization of two-loop integrals relevant to the calculation of the nucleon mass in the framework of manifestly Lorentz-invariant chiral perturbatio…
Improving the ultraviolet behavior in baryon chiral perturbation theory
D. Djukanovic, M. R. Schindler, J. Gegelia +1
We introduce a new formulation of baryon chiral perturbation theory which improves the ultraviolet behavior of propagators and can be interpreted as a smooth cutoff regularization…
Infrared regularization of baryon chiral perturbation theory reformulated
M. R. Schindler, J. Gegelia, S. Scherer
We formulate the infrared regularization of Becher and Leutwyler in a form analogous to our recently proposed extended on-mass-shell renormalization. In our formulation, IR regular…
Power counting in baryon chiral perturbation theory including vector mesons
T. Fuchs, M. R. Schindler, J. Gegelia +1
It is demonstrated that using a suitable renormalization condition one obtains a consistent power counting in manifestly Lorentz-invariant baryon chiral perturbation theory includi…
