Search for anomalous top quark couplings with the D0 detector

D0 Collaboration, V. Abazov

Anomalous Wtb couplings modify the angular correlations of the top quark decay products and change the single top quark production cross section. We present limits on anomalous top…

Resonant Cascaded Down-Conversion

Christian Weedbrook, Ben Perrett, Karen V. Kheruntsyan +3

We analyze an optical parametric oscillator (OPO) in which cascaded down-conversion occurs inside a cavity resonant for all modes but the initial pump. Due to the resonant cascade…

Observation of New Charmless Decays of Bottom Hadrons

CDF Collaboration, T. Aaltonen

We search for new charmless decays of neutral b-hadrons to pairs of charged hadrons with the upgraded Collider Detector at the Fermilab Tevatron. Using a data sample corresponding…

The Gaussian approximation for multi-color generalized Friedman's urn model

Li-Xin Zhang, Feifang Hu

The Friedman's urn model is a popular urn model which is widely used in many disciplines. In particular, it is extensively used in treatment allocation schemes in clinical trials.…
