Production and Decay of Scalar Stoponium Bound States
In this paper we discuss possible signatures for the production of scalar t̃1t̃ ∗ 1 (stoponium) bound states σt̃1 at hadron colliders, where t̃1 is the lighter scalar top eigenstate. We first study the decay of σt̃1 ; explicit expressions are given for all potentially important decay modes. If t̃1 has unsuppressed two–body decays, they will always overwhelm the annihilation decays of σt̃1 . Among the ...
متن کاملThe scalar glueball spectrum
We discuss scenarios for scalar glueballs using arguments based on sum rules, spectral decomposition, the 1 Nc approximation, the scales of the strong interaction and the topology of the flux tubes. We analyze the phenomenological support of those scenarios and their observational implications. Our investigations hint a rich low lying glueball spectrum. Pacs: 12.38-t, 12.38.Aw,14.70.-e, 14.70.-j
متن کاملUltrarelativistic bound states in spinor and scalar QED.
Producing the hadron spectrum from quantum chromodynamics (QCD) has proven to be a formidable task indeed. This is essentially because the low-energy modes in the theory couple strongly, making the problem inaccessible to perturbation theory. The strong-coupling problem can be divided (somewhat artificially) into two aspects. In a Fock-space expansion of the states, strong coupling will imply l...
متن کاملLight scalar meson spectrum
We discuss the classification of the light scalar mesons with mass below 2 GeV into qq̄ nonets and glueballs. The information on production and decay of these states, in particular recent information on the f0(980), f0(400−1200) (or σ(600)) and f0(1500) is considered. Although the data are not yet very precise the recent information is in favour of the previously developed scheme which includes ...
متن کاملScalar-Scalar Bound State in Non-commutative Space
Bethe-Salpeter equation in the non-commutative space for a scalarscalar bound state is considered. It is shown that in the non-relativistic limit, the effect of spatial non-commutativity appears as if there exist a magnetic dipole moment coupled to each particle. e-mail: [email protected] e-mail: [email protected] Non-commutativity of space-time has been recently a subject of intense ...
