Searches for heavy Higgs bosons in two-Higgs-doublet models and for t→ch decay using multilepton and diphoton final states in pp collisions at 8 TeV

Searches are presented for heavy scalar (H) and pseudoscalar (A) Higgs bosons posited in the two doublet model (2HDM) extensions of the standard model (SM). These searches are based on a data sample of pp collisions collected with the CMS experiment at the LHC at a center-of-mass energy of root s = 8 TeV and corresponding to an integrated luminosity of 19.5 fb(-1). The decays H -> hh and A -> Zh, where h denotes an SM-like Higgs boson, lead to events with three or more isolated charged leptons or with a photon pair accompanied by one or more isolated leptons. The search results are presented in terms of the H and A production cross sections times branching fractions and are further interpreted in terms of 2HDM parameters. We place 95% C.L. cross section upper limits of approximately 7 pb on sigma B for H -> hh and 2 pb for A -> Zh. Also presented are the results of a search for the rare decay of the top quark that results in a charm quark and an SM Higgs boson, t -> ch, the existence of which would indicate a nonzero flavor-changing Yukawa coupling of the top quark to the Higgs boson. We place a 95% C.L. upper limit of 0.56% on B(t -> ch).

George C. Martin Papers - Accession 271 - M117 (149-150)

The George C. Martin Papers includes Civil War correspondence between George Canning Martin and his wife, Sarah Jane, from May 1862 to August 1864. Subjects include camp life, the progress of the war in North Carolina and Virginia, and the physical and mental condition of the Confederate soldiers (such as ill health, poor food, and depression). Also included are tax receipts, pension records, newspapers clippings (1863), a commonplace book belonging to Robert Smith, and a memoir (author unknown).

Book Review of Raising Less Corn, More Hell: The Case for the Independent Farm and Against Industrial Food by George Pyle

Raising Less Corn, More Hell may sound like a rallying cry for the nation's heartland farmers, but this well-written series of essays by George Pyle is meant for those who eat corn. Or rather, for those of us who eat the livestock fed on corn in confined animal feeding operations, then wash down those meals with drinks high in high-fructose corn syrups. Pyle, an editorial writer from Kansas now living in Utah, brings his journalist's skills to bear on what our industrial food system has brought us. It's not appetizing as he makes his case against a corporate-controlled system that doesn't have to be this way.
