We present in detail a technique to extract the potential between a static quark and anti-quark pair from Wilson loops measured on dynamical configurations. This technique is based on HYP smearing and leads to an exponential improvement of the noise-to-signal ratio of Wilson loops. We explain why the correct continuum potential is obtained and show numerical evidence that the cut-off effects ar...

We present results from simulations of two dynamical flavors of improved Wilson fermions with nHYP smeared gauge links. We demonstrate that the simulation is stable at a pseudo-scalar mass of 360MeV, a 2.1fm box and a lattice spacing of 0.13fm.

We report on recent progress in the calculation of BK using HYP-smeared staggered fermions on the MILC asqtad lattices. Our main focus is on the continuum extrapolation, which is done using (up to) four different lattice spacings—a ≈ 0.12, 0.09, 0.06 and 0.045 fm. Since Lattice 2010, we have reduced the statistical errors on the a ≈ 0.09 fm lattices by a factor of ∼ 3, and roughly doubled the s...

We present results for the pion multiplet spectrum calculated using both unimproved staggered fermions and improved HYP-smeared staggered fermions. In the case of unimproved staggered fermions, we observe (consistent with previous work) that O(a2) taste symmetry breaking effects are large and comparable to the ≈ O(p2) contributions to their masses. Higher order O(a2 p2) effects are also substan...

William Empson’s poem ‘Letter I’ (1928–35) appears to anticipate the black hole, using the idea of a dying star from which no light escapes as a metaphor for unrequited passion. Closer inspection of the Cambridge undergraduate context in which the poem was written, along with the other source materials incorporated besides Arthur Eddington in the poem, reveals the motivation behind Empson’s pla...

Model studies of the influence lectin-containing extracts medicinal plants St. John's wort (Hypericum perforatum L.), common yarrow (Achillea millefolium marigold (Calendula officinalis L.) and dwarf evergreen (Helichrysum arenarium (L.) Moench.) on growth development wheat, oat, barley rye at beginning their ontogenesis. They testify to specificity action in relation model objects, which is pr...

This paper investigates the role of parental retirement wealth in determining offspring wealth. We examine a prominent policy change to Social Security benefit determination, the Notch, in which a handful of birth cohorts received higher benefits relative to neighboring cohorts. Using multiple datasets, we find that the effect of the policy change on the wealth distribution of the children of a...

We present exploratory results for the hadron mass spectrum and pseudoscalar meson decay constants using mixed actions. We use improved staggered sea quarks and HYP-smeared overlap valence quarks. We obtain good signals on 10 configurations at one lattice spacing and two different sets of sea quark masses.

We give an update on our calculation of BK using HYP-smeared valence staggered quarks. We have results for BK at tree-level on several coarse MILC lattices (a ≈ 0.12fm) and one of the fine lattices (a ≈ 0.09fm), using 10 light valence quarks ranging down to m s /10. We have generalized staggered chiral perturbation theory to our mixed action setup, and outline the results. We explain our presen...
