Measurement of the pp(-)-> W gamma plus X cross section at root s=1.96 TeV and WW gamma anomalous coupling limits

The WWγ triple gauge boson coupling parameters are studied using pp̄rarr; νγ+X(=e,μ) events at s=1.96 TeV. The data were collected with the D0 detector from an integrated luminosity of 162pb-1 delivered by the Fermilab Tevatron Collider. The cross section times branching fraction for pp̄→W(γ)+X→ νγ+X with ETγ>8 GeV and ΔR γ> 0.7 is 14.8±1.6(stat)±1.0(syst) ±1.0(lum)pb. The one-dimensional 95% confidence level limits on anomalous couplings are -0.88<Δκγ<0.96 and -0. 20<λγ<0.20. © 2005 The American Physical Society.

Measurement of the tt̄ production cross section in pp̄ collisions at √s = 1.96 TeV in dilepton final states

We present a measurement of the top quark pair (tt̄) production cross section in pp̄ collisions at √s=1.96 TeV using events with two charged leptons in the final state. This analysis utilizes an integrated luminosity of 224-243 pb-1 collected with the DØ detector at the Fermilab Tevatron Collider. We observe 13 events in the e+e -, eμ and μ+μ- channels with an expected background of 3.2±0.7 events. For a top quark mass of 175 GeV, we measure a tt̄ production cross section of σtt̄=8. 6-2.7 +3.2(stat)±1.1(syst)±0.6(lumi) pb, consistent with the standard model prediction. © 2005 Elsevier B.V.

Search for squarks and gluinos in events with jets and missing transverse energy in p(p)over-bar collisions at root s-=1.96 TeV

The results of a search for squarks and gluinos using data from p over(p, ̄) collisions recorded at a center-of-mass energy of 1.96 TeV by the DØ detector at the Fermilab Tevatron Collider are reported. The topologies analyzed consist of acoplanar-jet and multijet events with large missing transverse energy. No evidence for the production of squarks or gluinos was found in a data sample of 310 pb-1. Lower limits of 325 and 241 GeV were derived at the 95% C.L. on the squark and gluino masses, respectively, within the framework of minimal supergravity with tan β = 3, A0 = 0, and μ < 0. © 2006 Elsevier B.V.

Search for associated Higgs boson production WH→WWW *→l±νl′±ν′+X in pp̄ collisions at s=1.96TeV

We present a search for associated Higgs boson production in the process pp̄→WH→WWW*→l±νl′±ν′ +X in final states containing two like-sign isolated electrons or muons (e±e±, e±μ±, or μ±μ±). The search is based on D0 run II data samples corresponding to integrated luminosities of 360-380pb-1. No excess is observed over the predicted standard model background. We set 95% C.L. upper limits on σ(pp̄→WH) ×Br(H→WW*) between 3.2 and 2.8 pb for Higgs boson masses from 115 to 175 GeV. © 2006 The American Physical Society.

Z gamma production and limits on anomalous ZZ gamma and Z gamma gamma couplings in pp collisions at root s=1.96 TeV

We present a study of eeγ and μμγ events using 1109 (1009) pb-1 of data in the electron (muon) channel, respectively. These data were collected with the DØ detector at the Fermilab Tevatron p over(p, ̄) collider at sqrt(s) = 1.96   TeV. Having observed 453 (515) candidates in the eeγ (μμγ) final state, we measure the Zγ production cross section for a photon with transverse energy ET > 7   GeV, separation between the photon and leptons Δ Rℓ γ > 0.7, and invariant mass of the di-lepton pair Mℓ ℓ > 30   GeV / c2, to be 4.96 ± 0.30 (stat . + syst .) ± 0.30 (lumi .)   pb, in agreement with the Standard Model prediction of 4.74 ± 0.22   pb. This is the most precise Zγ cross section measurement at a hadron collider. We set limits on anomalous trilinear Zγγ and ZZγ gauge boson couplings of - 0.085 < h30 γ < 0.084, - 0.0053 < h40 γ < 0.0054 and - 0.083 < h30 Z < 0.082, - 0.0053 < h40 Z < 0.0054 at the 95% C.L. for the form-factor scale Λ = 1.2   TeV.

Search for Randall-Sundrum gravitons with 1 fb(-1) of data from p(p)over-bar collisions at root s=1.96 TeV

We search for decays of Kaluza-Klein excitations of the graviton in the Randall-Sundrum model of extra dimensions to e+e- and in 1 fb-1 of pp collisions at s=1.96 TeV collected by the D0 detector at the Fermilab Tevatron. We set 95% confidence level upper limits on the production cross section times branching fraction, which translate into lower limits on the mass of the lightest excitation between 300 and 900 GeV for values of the coupling k/M Pl between 0.01 and 0.1. © 2008 The American Physical Society.

Search for scalar neutrino superpartners in e+mu final states in p(p)over-bar collisions at root s=1.96 TeV

We report a search for R-parity-violating production and decay of sneutrino particles in the eμ final state with 1.04±0.06fb-1 of data collected with the D0 detector at the Fermilab Tevatron Collider in 2002-2006. Good agreement between the data and the standard model prediction is observed. With no evidence for new physics, we set limits on the R-parity-violating couplings λ311′ and λ312 as a function of the sneutrino mass. © 2008 The American Physical Society.

(In)VERSÕES POLÍTICO-ESCATOLÓGICAS NO PENTECOSTALISMO BRASILEIRO Uma análise da posição e ação política das Assembleias de Deus de 1930-1945 e 1978-1988 a partir do jornal Mensageiro da Paz

A presente pesquisa analisou a posição e ação política nas Assembleias de Deus do Brasil nos períodos 1930-1945 e 1978-1988. Defendemos a tese de que desde 1930 há no interior do pentecostalismo brasileiro posições e intervenções no mundo da política. Tanto no período de 1930-1945 como o de 1978-1988 nossas análises serão realizadas a partir das temporalidades discutidas por Giorgio Agamben: chronos, aiôn e kairos. No que diz respeito ao primeiro período 1930-1945, as pesquisas quase sempre vinculam o discurso escatológico do pentecostalismo a processos de alienação e não envolvimento com a política partidária. Entretanto, acredita-se que as narrativas escatológicas não foram causa de certo afastamento da esfera pública brasileira, mas sim efeito de processos de exclusão aos quais homens e mulheres de pertença pentecostal estiveram circunscritos. Doutrinas como a escatologia e a pneumatologia foram potencializadoras de processos que aqui denominamos de biopotência. Já no segundo período, de 1978-1988, a posição e a ação política que predominaram no pentecostalismo estiveram relacionadas com a biopolítica. Chamamos de capítulo intermedário ou de transição o período correspondente às datas 1946-1977. Nele descreveremos e analisaremos personalidades pentecostais de destaque no campo da política brasileira. Metodologicamente, fizemos nossa análise a partir de artigos publicados no órgão oficial de comunicação da denominação religiosa em questão, o jornal Mensageiro da Paz. Esse periódico circula desde 1930. Além dos artigos, destacamos também as autoras e os autores, todas elas e todos eles figuras de destaque no assembleianismo. Ao longo da pesquisa questionamos a ideia do apoliticismo pentecostal. Defendemos a tese de que desde 1930, que é o início de nossa pesquisa, há posição e ação política nas Assembleias de Deus. Como resultado disso, questionamos a ideia do apoliticismo pentecostal. Nossa hipótese é de que no período 1930-1945 o pentecostalismo foi um polo de biopotência. Se a biopolítica é o poder sobre a vida, a biopotência é o poder da vida. Doutrinas como a escatologia e pneumatologia contribuíram para que nos espaços marginais onde se reuniam os pentecostais fossem criados novos modelos de sociabilidade e de cooperação; eram também espaços de criação de outras narrativas e de crítica a modelos hegemônicos e excludentes. O pentecostalismo foi um movimento que promoveu a dignidade humana de sujeitos subalternos.

Catharine Waugh McCullouch papers in the Mary Earhart Dillon collection, 1869-1945

Collection primarily documents McCulloch's research on women's legal status, and her work with the Illinois Equal Suffrage Association, the National American Woman Suffrage Association, and the League of Women Voters. There is also documentation of women in the legal profession, of McCulloch's friendships with the other women suffragists and lawyers, and some biographical material. The papers contain little information about her family or social life.
