Prospect of D0 mixing and CPV at LHCb
Precision measurements in charm physics offer a window into a unique sector
of potential New Physics interactions. LHCb is poised to become a world leading
experiment for charm studies, recording enormous statistics with a detector
tailored for flavor physics. This article presents recent charm CPV and mixing
studies from LHCb, including LHCb's first CP asymmetry measurement with 37
inverse pb of data collected in 2010. The difference of the CP asymmetries of
D0 decays to the K-K+ and \pi-\pi+ final states is determined to be \Delta
A_{CP} = (-0.28 +/- 0.70 +/- 0.25)%. Significant updates to the material
presented at the 4th International Workshop on Charm Physics are included.Comment: 5 pages, 4 figures. Submitted to the proceedings of the 4th

Diffractive Results from the Tevatron
Hard diffraction in events with dijets and rapidity gaps has been studied by
D\O and CDF for three processes: hard color singlet exchange, hard single
diffraction, and hard double pomeron exchange, using Tevatron data at
= 630 GeV and 1.8 TeV. Measurements of rates, and
dependencies are presented and comparisons made with predictions of
several models.Comment: Presented at DPF99, 8 pages, 6 figure
