    Using SU(3) Relations to bound the CP Asymmetries in BKKKB \to KKK decays

    Full text link
    We consider three body Δs=1\Delta s = 1 BfB \to f decays with f=KKKf=KKK. The deviations of ηfSf-\eta_f S_f from SψKSS_{\psi K_S} and of CfC_f from zero can be bounded using the approximate SU(3) flavor symmetry of the strong interactions and branching ratios of various Δs=0\Delta s = 0 modes. We present the most promising SU(3) amplitude relations that can be used to obtain these bounds.Comment: 14 pages, revtex

    Should we solve Plateau's problem again?

    Full text link
    After a short description of various classical solutions of Plateau's problem, we discuss other ways to model soap films, and some of the related questions that are left open. A little more attention is payed to a more specific model, with deformations and sliding boundary conditions.Comment: Lecture for the conference in Honor of E. Stein, 201

    Thinking Twice about Virtue and Vice: Philosophical Situationism and the Vicious Minds Hypothesis

    This paper provides an empirical defense of credit theories of knowing against Mark Alfano’s challenges to them based on his theses of inferential cognitive situationism and of epistemic situationism. In order to support the claim that credit theories can treat many cases of cognitive success through heuristic cognitive strategies as credit-conferring, the paper develops the compatibility between virtue epistemologies qua credit theories, and dual-process theories in cognitive psychology. It also a response to Lauren Olin and John Doris’ “vicious minds” thesis, and their “tradeoff problem” for virtue theories. A genuine convergence between virtue epistemology and dual-process theory is called for, while acknowledging that this effort may demand new and more empirically well-informed projects on both sides of the division between Conservative virtue epistemology (including the credit theory of knowing) and Autonomous virtue epistemology (including projects for providing guidance to epistemic agents)
