  1. We present an update of the results presented in 1, using 3.1 pb1. In this update the analysis underwent only minor modifications due to changes in the trigger. No resonances were found in the updated sample. We improved the limits set on the…
  2. In the classical theory black holes can only absorb and not emit particles. However it is shown that quantum mechanical effects cause black holes to create and emit particles as if they were hot bodies with temperature ~ ~ 10 where ~ is the surface…
  3. The OPERA neutrino experiment at the underground Gran Sasso Laboratory has measured the velocity of neutrinos from the CERN CNGS beam over a baseline of about 730 km with much higher accuracy than previous studies conducted with accelerator…
  4. We argue that the following three statements cannot all be true: (i) Hawking radiation is in a pure state, (ii) the information carried by the radiation is emitted from the region near the horizon, with low energy effective field theory valid beyond…
  5. A combination of results on the rare decays B 0 s ! m +m and B 0 d ! m +m from the CMS and LHCb experiments is performed. After accounting for known correlations, the average time-integrated branching fraction of the decay B 0 s ! m +m is determined…
  6. We establish a direct connection between scattering amplitudes in planar four-dimensional theories and a remarkable mathematical structure known as the positive Grassmannian. The central physical idea is to focus on on-shell diagrams as objects of…
  7. General conditions for dynamical supersymmetry breaking are discussed. Very small effects that would usually be ignored, such as instantons of a grand unified theory, might break supersymmetry at a low energy scale. Examples are given (in 0 + 1 and…
  8. A general introduction to the topological mechanism responsible for the absolute confinement of quarks inside hadronic bound states is given, including the effects of a finite instanton angle. We then propose a calculational technique for computing…
