Accuracy of Approximate Eigenstates [PDF]
, 1999 Besides perturbation theory, which requires, of course, the knowledge of the exact unperturbed solution, variational techniques represent the main tool for any investigation of the eigenvalue problem of some semibounded operator H in quantum theory.

Mission Target: Tetraquark Mesons of Flavour-Cryptoexotic Type
Universe, 2023 Currently, flavour-cryptoexotic tetraquarks form the most common sort of all experimentally established exotic multiquark hadrons. This note points out a few promising concepts that should help improve theoretical (but, for several reasons, not quite ...

Various illustrative brief glances at the flavour-cryptoexotic tetraquark states [PDF]
EPJ Web of ConferencesConstituting the largest subset of multiquark states so far observed by experiment, tetraquark mesons carrying overall quark flavour quantum numbers identical to those of the (conventional) quark–antiquark mesons necessitate their particularly deliberate

Can one control systematic errors of QCD sum rule predictions for bound states? [PDF]
, 2007 We study the possibility to control systematic errors of the ground-state parameters obtained by Shifman-Vainshtein-Zakharov (SVZ) sum rules, making use of the harmonic-oscillator potential model as an example.
