Talk presented at the 32nd International Symposium on Lattice Field Theory (Lattice 2014), 23-28 June 2014, Columbia University, New York, NY \\ We examine the feasibility of the proposition that there is a temperature range T$_c$ < T < T$_{ch}$ in N$_f$=0 QCD, where real Polyakov line (deconfined) vacuum exhibits valence spontaneous chiral symetry breaking and dynamical chiral polarization of Dirac eigenmodes. Detailed finite-volume analysis convincingly demonstrates the existence of such phase at fixed cutoff (a=0.085 fm). Moreover, it is found that this behavior also takes place closer to the continuum limit (a=0.060 fm) without qualitative change in its properties. \\ ( http://arxiv.org/abs/1409.7094 , 3096kb) ------------------------------------------------------------------------------ \\ arXiv:1409.7103 Date: Wed, 24 Sep 2014 21:09:34 GMT (126kb) Title: Free-form Smeared Bottomonium Correlation Functions Authors: Mark Wurtz, Randy Lewis, R. M. Woloshyn Categories: hep-lat Comments: 7 pages, 5 figures, presented at the 32nd International Symposium on Lattice Field Theory, 23-28 June, 2014, Columbia University New York, NY \\ Gauge-invariant sources with a hydrogen wave function shape are constructed for bottomonium two-point correlation functions using the free-form smearing technique. The bottomonium spectrum, including a first lattice result for the D-wave first-excited state, is extracted from free-form smeared correlation functions. Results are compared with conventional smearing techniques and free-form smearing is found to have the advantage of reduced statistical errors. \\ ( http://arxiv.org/abs/1409.7103 , 126kb) ------------------------------------------------------------------------------ \\ arXiv:1409.7139 Date: Thu, 25 Sep 2014 02:21:42 GMT (88kb,D) Title: Finite-volume effects and the electromagnetic contributions to kaon and pion masses Authors: S. Basak, A. Bazavov, C. Bernard, C. DeTar, E. Freeland, J. Foley, Steven Gottlieb, U.M. Heller, J. Komijani, J. Laiho, L. Levkova, J. Osborn, R.L. Sugar, A. Torok, D. Toussaint, R.S. Van de Water, R. Zhou, for the MILC Collaboration Categories: hep-lat hep-ph Comments: 7 pages, 2 figures. Presented at Lattice 2014, Columbia University, June 23-28, 2014 \\ We report on the MILC Collaboration calculation of electromagnetic effects on light pseudoscalar mesons. The simulations employ asqtad staggered dynamical quarks in QCD plus quenched photons, with lattice spacings varying from 0.12 to 0.06 fm. Finite volume corrections for the MILC realization of lattice electrodynamics have been calculated in chiral perturbation theory and applied to the lattice data. These corrections differ from those calculated by Hayakawa and Uno because our treatment of zero modes differs from theirs. Updated results for the corrections to "Dashen's theorem" are presented. \\ ( http://arxiv.org/abs/1409.7139 , 88kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:1409.4557 (*cross-listing*) Date: Tue, 16 Sep 2014 09:52:43 GMT (836kb,D) Title: $B\to K^{(*)}\nu\bar\nu$ decays in the Standard Model and beyond Authors: Andrzej J. Buras, Jennifer Girrbach-Noe, Christoph Niehoff and David M. Straub Categories: hep-ph hep-ex hep-lat Comments: 39 pages, 11 figures Report-no: FLAVOUR(267104)-ERC-80 \\ We present an analysis of the rare exclusive $B$ decays $B\to K\nu\bar\nu$ and $B\to K^{*}\nu\bar\nu$ within the Standard Model (SM), in a model-independent manner, and in a number of new physics (NP) models. Combining new form factor determinations from lattice QCD with light-cone sum rule results and including complete two-loop electroweak corrections to the SM Wilson coefficient, we obtain the SM predictions $\text{BR}(B^+\to K^+\nu\bar\nu) = (4.2 \pm 0.4) \times 10^{-6}$ and $\text{BR}(B^0\to K^{* 0}\nu\bar\nu) = (9.9\pm0.8) \times 10^{-6}$, more precise and more robust than previous estimates. Beyond the SM, we make use of an effective theory with dimension-six operators invariant under the SM gauge symmetries to relate NP effects in $b\to s\nu\bar\nu$ transitions to $b\to s\ell^+\ell^-$ transitions and use the wealth of experimental data on $B\to K^{(*)}\ell^+\ell^-$ and related modes to constrain NP effects in $B\to K^{(*)}\nu\bar\nu$. We then consider several specific NP models, including $Z'$ models, the MSSM, models with partial compositeness, and leptoquark models, demonstrating that the correlations between $b\to s\nu\bar\nu$ observables among themselves and with $B_s\to\mu^+\mu^-$ and $b\to s\ell^+\ell^-$ transitions offer powerful tests of NP with new right-handed couplings and non-MFV interactions. \\ ( http://arxiv.org/abs/1409.4557 , 836kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% %%%---%%%---%%%---%%%---%%%---%%%---%%%---%%%---%%%---%%%---%%%---%%%---%%%--- For subscribe options to combined physics archives, e-mail To: physics@arXiv.org, Subject: subscribe ----------------------------------------------------------------------------- For help on viewing and making submissions, see http://arXiv.org/help/ For a list of archive mirror sites, see http://arXiv.org/servers.html ----------------------------------------------------------------------------- Third-party submissions cause excessive problems.
