Short-range production of three bottom mesons
Yong-Hui Lin, Hans-Werner Hammer, Ulf-G. Meißner
Previous investigations of the three-body dynamics of mesons have shown that no Efimov effect arises in systems composed of three and mesons. This implies that the pr…
Model-independent mass determination of near-threshold states from short-range production
Yong-Hui Lin, Hans-Werner Hammer, Ulf-G. Meißner
We propose a novel observable for the precision measurements of a wide class of near-threshold dimer states: the short-range production rate of a dimer--spectator two-body system,…
Renormalizing the Quark-Meson-Diquark Model
Hosein Gholami, Lennart Kurth, Ugo Mire +2
We present a comprehensive study of the two-flavor Quark--Meson--Diquark (QMD) model by comparing a renormalization approach with a renormalization-group (RG) consistent mean-field…
Color superconductivity under neutron-star conditions at next-to-leading order
Andreas Geißel, Tyler Gorda, Jens Braun
The equation of state of deconfined strongly interacting matter at high densities remains an open question, with effects from quark pairing in the preferred color-flavor-locked (CF…
Renormalization-group consistent treatment of color superconductivity in the NJL model
Hosein Gholami, Marco Hofmann, Michael Buballa
The Nambu-Jona-Lasinio (NJL) model and specifically its extension to color superconductivity (CSC) is a popular effective model for investigating dense quark matter. However, the r…
On the sensitivity of nuclear clocks to new physics
Andrea Caputo, Doron Gazit, Hans-Werner Hammer +4
The recent demonstration of laser excitation of the eV isomeric state of Thorium-229 is a significant step towards a nuclear clock. The low excitation energy likely res…
