Heavy quark expansion parameters from lattice NRQCD [PDF]
, 2003 We present a lattice QCD calculation of the heavy quark expansion parameters $\mu_{\pi}^2$ and $\mu_G^2$ for heavy-light mesons and heavy-light-light baryons.

The pionium lifetime in generalized chiral perturbation theory [PDF]
, 2000 Pionium lifetime corrections to the nonrelativistic formula are calculated in the framework of the quasipotential-constraint theory approach. The calculation extends an earlier evaluation, made in the scheme of standard chiral perturbation theory, to the

Fission life-time calculation using a complex absorbing potential
EPJ Web of Conferences, 2016 A comparison between the semi-classical approximation and the full quantum calculation with a complex absorbing potential is made with a model of the fission of 258Fm. The potential barrier is obtained with the constrained Skyrme HF+BCS theory.
