Measurement of differential cross sections for the production of a pair of isolated photons in pp collisions at root s=7TeV

A measurement of differential cross sections for the production of a pair of isolated photons in proton-proton collisions at root s = 7 TeV is presented. The data sample corresponds to an integrated luminosity of 5.0 fb(-1) collected with the CMS detector. A data-driven isolation template method is used to extract the prompt diphoton yield. The measured cross section for two isolated photons, with transverse energy above 40 and 25 GeV respectively, in the pseudorapidity range vertical bar eta vertical bar < 2.5, vertical bar eta vertical bar (sic) [1.44, 1.57] and with an angular separation Delta R > 0.45, is 17.2 +/-0.2 (stat) +/-1.9 (syst) +/- 0.4 (lumi) pb. Differential cross sections are measured as a function of the diphoton invariant mass, the diphoton transverse momentum, the azimuthal angle difference between the two photons, and the cosine of the polar angle in the Collins-Soper reference frame of the diphoton system. The results are compared to theoretical predictions at leading, next-to-leading, and next-to-next-to-leading order in quantum chromodynamics.

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).

Lincoln Downtown Rotary Club

Good afternoon, and thank you for inviting me to be here with you today. One of the things I'm enjoying most in my new position as University of Nebraska Vice President of Agriculture and Natural Resources and Harlan Vice Chancellor of the Institute of Agriculture and Natural Resources is meeting the people who live in this state, in urban and rural areas, from Scottsbluff to Omaha, from Lincoln to Curtis, and at any number of towns - north, south, east, west - in between.

Football Pregame

Good afternoon! I am John Owens, and it is my good fortune to be Vice President and Vice Chancellor of Agriculture and Natural Resources. Chancellor Harvey Perlman certainly regrets that he cannot be present at today’s pregame reception. His daughter is being recognized at Ak-Sar-Ben in Omaha, and he’s celebrating this very special occasion with his family. And speaking of family, I would like to introduce my wife, Dr. Virginia Owens. This probably is the right time for me to confess that both Virginia and I are graduates of Texas Tech. Now, we want everyone to know that “alumni loyalty” can go just so far… and we always cheer for the Huskers!

Welcome

It is a real pleasure to have this opportunity to visit Bluebird Nurseries and talk with everyone gathered here, and I join John Trumbull in welcoming you this morning. I am looking forward to learning more about the Nebraska nursery industry today, and I look forward to visiting and working with you now, and in the days ahead. Getting to know Nebraska and its residents is one of the real pleasures of my new job, and has been since I started in January. My wife Virginia and I literally slid into the state one snowy day last December - almost hard to remember that icy, snowy winter, given the past few months - and ever since our arrival we have been impressed and delighted by the friendliness and warmth of Nebraska's residents. This is a great state, and we are very happy to be here. As I welcome you I also want to offer Chancellor Harvey Perlman's regrets that he could not accept the invitation to be here, too; he is unable to join us because of conflicts in schedule.

Nebraska Agribusiness Club

Thank you for inviting me to be here with you today. I've now completed four months as University of Nebraska Vice President for Agriculture and Natural Resources and Harlan Vice Chancellor of the Institute of Agriculture and Natural Resources, and I welcome every opportunity that comes my way to meet and talk with Nebraska's residents. I'm particularly happy to be here with you; I appreciate your interest in agriculture, and Ed Woeppel tells me that many members of this group are very supportive of the Institute, and worked hard to create IANR in the '70s.
