In this paper I want to present a new proposal for a unified meaning of the particle only which accounts for the traditional distinction between a quantificational and a scalar only. It therefore avoids an unintuitive lexical ambiguity and tries to capture a generalization missed so far. For this purpose, different stages in the history of only will be reviewed, portraying the increasing comple...

We discuss the phenomenology of colour scalar octet particles. Namely, we consider the discovery potential of scalar octets at LEP, FNAL and LHC. Octet scalars decay mainly into two gluino and new hadrons composed from scalar coloured octets are rather longlived (Γ ≤ O(10)Kev). For the scalar octet masses(M ≥ O(50)Gev) the scalar octets producing at FNAL or LHC will decay into two gluons that l...

We study the decays of a scalar (t̃1t̃ ∗ 1) bound state σt̃1 , where t̃1 is the lighter stop eigenstate. If t̃1 has no tree–level 2–body decays, the dominant decay modes of σt̃1 are gg or, if mh < mt̃1 ≪ mt̃2 , a pair of light scalar Higgs bosons h. The best signal for σt̃1 production at hadron colliders is probably its decay into two photons. Contribution to the Proceedings of the Madison–Argonne Hadro...
