Research interests

My research interests concern phenomenological problems in theoretical nuclear physics. While my interests are diverse and lead me to work on a  multitude of problems, I am especially attracted to problems providing insight into new physics beyond the Standard Model (SM). 

Of special importance is the precision analysis of neutron beta-decays, which provides an excellent laboratory for the search of new physics beyond the SM. The continuously increasing experimental accuracy, demands also from the theory side to ”keep up” and improve the theoretical accuracy. There are manifold problems to be dealt with here.

Another topic of investigation concerns the evaluation of hadronic electric dipole moments (EDMs), especially of the neutron. Since EDM contributions from the SM are highly suppressed, while most beyond SM physics models naturally predict comparably large contributions, EDMs constitute a practically background free observable for physics beyond the SM. 

In order to correlate EDM measurements of a hadronic system, like the neutron, with bounds on new high energy physics models, e.g. SUSY, GUTs etc., one has to evaluate hadronic matrix elements. This constitutes a highly non-trivial problem, since it necessitates to deal with QCD in the non-perturbative regime. The effects of new physics at the hadronic scale can be encoded in terms of a collection of effective field operators. The main task consists of evaluating the EDM of the neutron as induced by those field operators. To be more precise, one 

has to express the EDM of the neutron as a function of the Wilson coefficients of the corresponding field operators. While Effective Field Theory generically provides crucial input on EDMs, it contains certain unknown low energy constants (LECs), which have to be
obtained 
by employing other techniques. One of the techniques, which principally satisfies those demands, is based on QCD Dyson-Schwinger equations. My research in this topic concerns the calculation of the neutron’s EDM as generated by the leading effective operators, which is one of the outstanding problems related to EDMs. 


Together with Hartmut Abele and co-workers we are searching for new physics (extra dimensions, axions, torsion gravity…) by employing the Q-bounce experiment.

 

 

Conference Organisation

I am organiser of ECT*-workshop: Dyson-Schwinger Equations in Modern Mathematics & Physics

This workshop aims at bringing together physicists working on DSE in hadron physics, quantum gravity and physics beyond the SM with mathematicians working on Hopf algebras etc.
