Hybrid meson decay from the lattice [PDF]
, 2002 We discuss the allowed decays of a hybrid meson in the heavy quark limit. We deduce that an important decay will be into a heavy quark non-hybrid state and a light quark meson, in other words, the de-excitation of an excited gluonic string by emission of

Constructing Hybrid Baryons with Flux Tubes [PDF]
, 1999 Hybrid baryon states are described in quark potential models as having explicit excitation of the gluon degrees of freedom. Such states are described in a model motivated by the strong coupling limit of Hamiltonian lattice gauge theory, where three flux ...

Electronic excitations from a linear-response range-separated hybrid scheme [PDF]
, 2013 We study linear-response time-dependent density-functional theory (DFT) based on the single-determinant range-separated hybrid (RSH) scheme, i.e. combining a long-range Hartree-Fock exchange kernel with a short-range DFT exchange-correlation kernel, for ...

Thermal Analysis of Dual-Axis-Direction Hybrid Excitation Generator for Electric Vehicles
Energies, 2022 Electric vehicle (EV) generators have characteristics of small volume and high power density, which leads to high temperature rise. The temperature rise will directly influence the service life and reliability of the generator, so thermal analysis of EV ...

Instability strips of SPB and beta Cephei stars: the effect of the updated OP opacities and of the metal mixture [PDF]
, 2006 The discovery of $\beta$ Cephei stars in low metallicity environments, as well as the difficulty in theoretically explaining the excitation of the pulsation modes observed in some $\beta$ Cephei and hybrid SPB-$\beta$ Cephei pulsators, suggest that the ``
