Semileptonic decays of heavy tetraquarks.
There exist heavy tetraquark states QQq̄q̄ in the heavy quark limit. These states are stable with respect to strong interactions and hence must decay weakly. It is shown that the semileptonic decay depends on a single Isgur– Wise form factor, which can be expressed in term of the Isgur–Wise form factors which govern the semileptonic decays of the Qqq and QQq baryons. Typeset using REVTEX 1 The po...
متن کاملSecondary Wave (s-wave)
Discussion S waves are seismic body waves meaning they travel through the Earth’s interior. Their velocity is slower than that of P waves, and they are normally the second major phase to be observed on a seismogram, and are therefore also referred to as secondary waves. In the Earth’s crust, S wave velocities are typically 3–4 km/s. S waves are usually larger in amplitude than P waves and may c...
متن کاملBottom friction effects on linear wave propagation
Bottom boundary layer effects on the linear wave propagation over mild slope bottoms are analyzed. A modifiedWKB approximation is presented including boundary layer effects. Within the boundary layer, two cases are considered: laminar (constant viscosity) and turbulent. Boundary layer effects are introduced by coupling the velocity inside the boundary layer to the irrotational velocity in the c...
متن کاملHyperspherical harmonic formalism for tetraquarks
We present a generalization of the hyperspherical harmonic formalism to study systems made of quarks and antiquarks of the same flavor. This generalization is based on the symmetrization of the N−body wave function with respect to the symmetric group using the Barnea and Novoselsky algorithm. Our analysis shows that four-quark systems with non-exotic 2 quantum numbers may be bound independently...
متن کاملThe Dπ S-wave
A pole in the Dπ S-wave analogous to the σ and κ is predicted at M− iΓ/2 = 2098± 40− i(260 ± 40) MeV. The main objective of this paper is to provide formulae for fitting it to data. PACS numbers: 12.39.Ki, 13.25.Gv, 14.40.Lb. There are well-known σ and κ poles in ππ and Kπ. The objective of this paper is to predict analogous poles in Dπ and Bπ S-waves and provide appropriate parametrisations of...
