A search for time-integrated CP violation in D0→h−h+D^{0} \rightarrow h^{-}h^{+} decays

The LHCb Collaboration has recently observed evidence of CP violation in neutral D meson decays. CP violation in the charm sector is generically expected to be very small in the Standard Model, but can be enhanced in many models of new physics. In this document we will present the results of a search for time-integrated \CP violation in $D^0 \rightarrow h^- h^+$ with $(h=K,\pi)$ decays, performed with around 0.6 fb$^{-1}$ of data collected by LHCb in 2011. The difference in CP asymmetry between $D^0 \rightarrow K^- K^+$ and $D^0 \rightarrow \pi^- \pi^+$, $\Delta A_{CP} = A_{CP}(K^- K^+) - A_{CP}(\pi^- \pi^+)$ is measured to be $\Delta A_{CP} = [-0.82 \pm 0.21 (stat.) \pm 0.11 (syst.)]$ . This differs from the hypothesis of CP conservation by 3.5 sigma.Comment: to appear in the proceedings of The 5th International Workshop on Charm Physics (Charm 2012

\u3ci\u3e\u3cb\u3eElla Enchanted:\u3c/b\u3e\u3c/i\u3e Reclaiming Fairy Tales / Perpetuating Hollywood Standards

Feminists often denounce traditional fairy tales because they perpetuate the ideals of a patriarchal society by encouraging girls to behave like proper princesses and wait for charming princes to take charge and save the day. In response to these traditional fairy tales, many authors have tried to reclaim the realm of fairy tales for girls. These retellings feature active protagonists who are not scared of taking charge and do not need princes to save them. One example of this new fairy tale genre is the 1998 children\u27s novel Ella Enchanted by Gail Garson Levine, an untraditional feminist retelling of the story of Cinderella. This paper examines why, when it was adapted into a movie in 2004, this story is, shockingly, no longer an effective feminist text

Measuring the angle γ\gamma from penguin decays at LHCb

In this paper we present first LHCb results on charmless charged two- and three-body $B$ meson decays. In particular, using the first picobarn of integrated luminosity, LHCb observed the $B^{0}\rightarrow K^{+}\pi^{-}$ and $B^{+}\rightarrow K^{+}\pi^{+}\pi^{-}$ decays. Such decays provide an interesting way to determine the angle $\gamma$ of the Unitary Triangle, thanks to the possible presence of New Physics in the penguin loops.Comment: Proceedings of CKM2010, the 6th International Workshop on the CKM Unitarity Triangle, University of Warwick, UK, 6-10 September 201
