Electromagnetic Multipole Moments of Baryons

Electromagnetic moments of relativistic higher spin baryons

We point out a source of ambiguities in the measurements of the electromagnetic moments of spin-3/2 baryons which rely on relativistic Lagrangian models. An anambiguous relation between the parameters of the spin-3/2 electromagnetic Lagrangian and the electromagnetic moments of the spin-3/2 particle exits in general only for on-shell situation, while the measurements are done on “virtual” baryons.

Multipole Moments In

This paper contains discussion of the problem of motion of extended e.g. non point test bodies in multidimensional space. Extended bodies are described in terms of so called multipole moments. Using approximated form of equations of motion for extended bodies deviation from geodesic motion is derived. Results are applied to special form of space-time.

Multipole Moments of Static Spacetimes

Multipole moments of axisymmetric spacetimes

In this thesis we study multipole moments of axisymmetric spacetimes. Using the recursive definition of the multipole moments of Geroch and Hansen we develop a method for computing all multipole moments of a stationary axisymmetric spacetime without the use of a recursion. This is a generalisation of a method developed by Herberthson for the static case. Using Herberthson’s method we also devel...

Magnetic Moments of Heavy Baryons

First non-trivial chiral corrections to the magnetic moments of triplet (T ) and sextet (S(∗)) heavy baryons are calculated using Heavy Hadron Chiral Perturbation Theory. Since magnetic moments of the T -hadrons vanish in the limit of infinite heavy quark mass (mQ → ∞), these corrections occur at order O(1/(mQΛχ)) for T -baryons while for S(∗)-baryons they are of order O(1/Λχ). The renormalizat...
