” I Know She Invented Fire , but What Has She Done Recently ? ” or ” I Have Come to Praise Ch . , not Bury Her ! ” or ‘ On the Second Renaissance of Charm

چکیده
D oscillations, for which the B factories have found strong evidence, provide a new stage for our search for New Physics in heavy flavour dynamics. While the theoretical verdict on the observed values of xD and yD is ambiguous – they could be fully generated by SM dynamics, yet could contain also a sizable contribution from New Physics – such oscillations can enhance the observability of CP violation driven by New Physics. After emphasizing the unique role of charm among up-type quarks, I sketch the CP phenomenology for partial widths and final state distributions.

متن کاملReflections on Jennifer Saul's View of Successful Communication and Conversational Implicature
Saul (2002) criticizes a view on the relationship between speaker meaning and conversational implicatures according to which speaker meaning is exhaustively comprised of what is said and what is implicated. In the course of making her points, she develops a couple of new notions which she calls “utterer-implicature” and “audience-implicature”. She then makes certain claims about the relationshi...
متن کاملIn an instant.
You were with her today at the oncologist’s office. She already had a lump removed and found out that she’s positive for BRCA2. In an instant, her life was changed, and soon she had a full hysterectomy. Her uterus is gone. Her ovaries are gone. The surgery was done using a robot. The incisions were minor. Those wounds will heal. Harder to say about the rest of her, which is why I’m glad that yo...
متن کامل" I Have Come to Praise Charm, Not Bury It " 1 2
The case for further dedicated studies of charm dynamics is presented as driven by three complementary motivations: core lessons on QCD and nonperturbative dynamics in general can be learnt; those can be applied with great profit in analyses of B decays; charm decays offer a novel portal to New Physics in particular through CP studies.
