Glueball correlators as holograms
Hilmar Forkel
We investigate the dynamical content of both hard- and soft-wall approximations to holographic QCD by deriving the corresponding glueball correlation functions and by confronting t…
Holographic glueball structure
Hilmar Forkel
We derive and systematically analyze scalar glueball correlation functions in both the hard-wall and dilaton soft-wall approximations to holographic QCD. The dynamical content of t…
Linear meson and baryon trajectories in AdS/QCD
Hilmar Forkel, Michael Beyer, Tobias Frederico
An approximate holographic dual of QCD is constructed and shown to reproduce the empirical linear trajectories of universal slope on which the square masses of radially and orbital…
Linear square-mass trajectories of radially and orbitally excited hadrons in holographic QCD
Hilmar Forkel, Michael Beyer, Tobias Frederico
We consider a new approach towards constructing approximate holographic duals of QCD from experimental hadron properties. This framework allows us to derive a gravity dual which re…
New chiral-symmetry-breaking operators in pseudoscalar QCD sum rules
Hilmar Forkel
Nonperturbative Wilson coefficients associated with the leading chiral-symmetry-breaking operators in the operator product expansion of the pseudoscalar QCD correlation function ar…
Instantons and Glueballs
H. Forkel
We investigate the impact of instantons on scalar glueball properties in a largely model-independent analytical approach based on the instanton-improved operator product expansion…
