Pionic and kaonic atoms are well known systems bound by the electromagnetic interaction between charged mesons and nuclei. Systems of a neutral meson bound to a nucleus only by the strong interaction have not been observed so far. The talk describes the long way to the first indication of η’⊗11C mesic states. In a series of photoproduction experiments the interaction between the η’ meson and...
Traditional Bayesian methods for inferring neutron star properties from observations contain uncertainties from choices of equation of state models and parameters. We compare uncertainties using an alternative strategy using an analytical method for inverting the structure equations.
The observation of neutrinoless double beta decay (0νββ) would demonstrate lepton-number violation, showing physics Beyond the Standard Model, and would establish the Majorana nature of the neutrino. Despite decades of investigation, the search remains open, pursued through diverse isotopes and detection techniques. CUORE (Cryogenic Underground Observatory for Rare Events), operating at the...
The Standard Model as a very succesful theory of electroweak interactions postulates the basic assumption about the pure „V(ector)-A(xial vector)“ character of the interaction. Nevertheless, other types of weak interactions (Scalar, Tensor) are still not experimentally ruled out. Low-energy searches for these „forbidden components“ studying e.g. . β-ν angular correlations in β-decay are...
Centrality-dependent charged-hadron production in p-O collisions at top LHC energies is predicted based on a nonequilibrium-statistical relativistic diffusion model. Colour-glass condensate initial conditions are used in a three-sources momentum-space model for gluon-gluon, quark-gluon and gluon-quark sources. Our results [1] are to be compared with pseudorapidity distributions measured in...
