Bad light stops play.
all animals display profound variations in their physiology over a 24-h period, including changes in locomotor activity, hormone production, metabolism and neural activity. these rhythms are endogenously generated by the circadian system and provide a selective advantage by enabling organisms to anticipate both daily and seasonal changes in the environment. as a result, normal physiology is dyn...
متن کاملProbing pain pathways with light
We have witnessed an accelerated growth of photonics technologies in recent years to enable not only monitoring the activity of specific neurons, while animals are performing certain types of behavior, but also testing whether specific cells, circuits, and regions are sufficient or necessary for initiating, maintaining, or altering this or that behavior. Compared to other sensory systems, howev...
متن کاملScalar Stoponium
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...
متن کاملDark Matter, Light Stops and Electroweak Baryogenesis
We examine the neutralino relic density in the presence of a light top squark, such as the one required for the realization of the electroweak baryogenesis mechanism, within the minimal supersymmetric standard model. We show that there are three clearly distinguishable regions of parameter space, where the relic density is consistent with WMAP and other cosmological data. These regions are char...
متن کاملProbing Light Sbottoms with B Decays
We discuss recently reported experimental hints for a bottom squark with mass around 3.5 GeV decaying as b̃ → clν̃. We correlate the sbottom lifetime with the decay rates for b → b̃νν̃ and b → b̃νν̃ in the framework of a minimal supersymmetric model extended by righthanded (s)neutrinos. Confronting our results with the well-measured semileptonic branching ratio of B mesons we conclude that the light ...
