The photon polarization tensor in pulsed Hermite- and Laguerre-Gaussian beams

Felix Karbstein, Elena A. Mosman

In this article, we provide analytical expressions for the photon polarization tensor in pulsed Hermite- and Laguerre-Gaussian laser beams. Our results are based on a locally const…

Test of the multiquark structure of $a_{1} (1420)$ in strong two-body decays

Thomas Gutsche, Mikhail A. Ivanov, Jürgen G. Körner +2

We present an analysis of strong two-body decays of the $a_{1} (1420)$ with $J^{P C} = 1^{++}$ recently reported by the COMPASS Collaboration at CERN. Following the interpretation of t…

Role of QCD compositeness in the production of scalar and tensor mesons through single-photon annihilation $e^{+} e^{-} \to γ^{*} \to γ S (T)$

Alexandr G. Chumakov, Thomas Gutsche, Valery E. Lyubovitskij +1

We study the exclusive production of scalar $S = 0^{++}$ and tensor $T = 2^{++}$ mesons through single-photon annihilation $e^{+} e^{-} \to γ^{*} \to γ S (T)$ . Using QCD compositeness of t…

Decay chain information on the newly discovered double charm baryon state $Ξ_{cc}^{++}$

Thomas Gutsche, Mikhail A. Ivanov, Jürgen G. Körner +1

We interprete the new double charm baryon state found by the LHCb Collaboration in the invariant mass distribution of the set of final state particles $(Λ_{c}^{+} K^{-} π^{+} π^{+})$ as b…

$Z_{b} (10610)$ and $Z_{b}^{'} (10650)$ decays in a covariant quark model

Fabian Goerke, Thomas Gutsche, Mikhail A. Ivanov +2

We present a calculation of the strong decays of the exotic states $Z_{b} (10610)$ and $Z_{b}^{'} (10650)$ using a covariant quark model. We use a molecular-type four-quark current for the…

Tetraquarks in holographic QCD

Thomas Gutsche, Valery E. Lyubovitskij, Ivan Schmidt

Using a soft-wall AdS/QCD approach we derive the Schrödinger-type equation of motion for the tetraquark wave function, which is dual to the dimension-4 AdS bulk profile. The latter…
