Voice and Genre in Beethoven's Deux Grandes Sonates pour le Clavecin ou Piano-Forte avec un Violoncelle obligé, Op. 5

Description: This paper examines the generic aspect of Beethoven's Opus 5 Cello Sonatas (1796) from structuralist and post-structuralist perspectives, and explores the works from these viewpoints in order to gain insights into how the sonatas function as autonomous musical texts rather than historiographic documents of Beethoven's biography or transitional contributions in the development of the genre of the solo sonata as it was later cultivated. The insights offered by these perspectives argue for a recon… more

Selected Lute Music from Paris, Rés. Vmd. Ms. 27 from the Bibliothèque Nationale: Reconstruction, Edition, and Commentary

Description: Paris . Rés. Vmd. Ms. 27, known as Tl.1, or the Thibault Manuscript, is one of the earliest extant sources of lute music, containing twenty-four solos and eighty-six accompaniments for vocal compositions. The manuscript was copied in Italian lute tablature lacking rhythm signs, which makes it inaccessible for modern performance. Each selection contains a full score of the four-part vocal concordance, and the reconstructed lute part in both the original notation and keyboard transcription. The… more

Direct measurement of the W boson decay width in proton-antiproton collisions at s**(1/2) = 1.96-TeV

Description: This dissertation describes a direct measurement of the W boson total decay width, {Lambda}{sub W}, using the D0 detector at the Fermilab Tevatron Collider. The measurement uses an integrated luminosity of 177.3 pb{sup -1} data, collected during the 2002-2003 run. The width is determined from the shape of the transverse mass distribution, M{sub T}, by fitting the data in the tail region 100 < M{sub T} < 200 GeV. The result if {Lambda}{sub W} = 2.011 {+-} 0.093(stat) {+-} 0.107(syst) GeV.

Measurement of the t anti-t production cross-section at s**(1/2) = 1.96-TeV using lifetime tagging

Description: A measurement of the t{bar t} production cross section in the lepton+jets channels with the D0 detector at {radical}s = 1.96 TeV using the lifetime-tagging techniques is presented. The t{bar t} cross section is estimated from the combination of the e+jets and {mu}+jets channels. The obtained result {sigma}{sub t{bar t}} = 7.47{sub -1.14}{sup +1.22}(stat){sub -1.03}{sup +1.65}(syst) {+-} 0.49(lumi) pb is consistent with the Standard Model expectation.

Measurement of the Cross Section for Production of Prompt Diphoton in proton anti-proton Collisions at s**(1/2) = 1.96-TeV

Description: This thesis presents the measurement of prompt diphoton production rate in proton-antiproton collisions at a center-of-mass energy of 1.96 TeV using the upgraded Collider Detector at Fermilab (CDF II). This process deserves some attention for the following reasons. The H {yields} {gamma}{gamma} decay mode is an important channel for the Standard Model (SM) Higgs boson searches in the low mass region (M{sub H} < 130 GeV) at the forth coming LHC. In many models involving physics beyond the SM,… more

Measurement of the t anti-t production cross section in p anti-p collisions at s**(1/2) = 1.96-TeV

Description: The direct observation of the top quark was first achieved at the Tevatron proton anti-proton collider at Fermilab. This discovery completed the third generation quark sector where the top quark is expected to accompany the bottom quark in the weak isospin doublet. This dissertation discusses the experimental verification of the production cross section as predicted by the Standard Model.

Search for Anomalous Kinematics of Top Dilepton Events in Proton - Anti-proton Collisions at s**(1/2) = 1.96-TeV

Description: The author presents a search for anomalous kinematics of t{bar t} dilepton events in p{bar p} collisions at {radical}s = 1.96 TeV using 193 pb{sup -1} of data collected with the CDF II detector. They developed a new a priori technique designed to silate the subset in a data sample revealing the largest deviation from Standard Model expectations and to quantify the significance of this departure. In the four-variable space considered, no particular subset shows a significant discrepancy and they… more

Measurement of the t anti-t Cross-Section Using the Dimuon Channel in p anti-p Collisions at s**(1/2) = 1.96-TeV

Description: The author has measured the t{bar t} production cross section at {radical}s = 1.96 TeV using data collected by the D0 experiment at Fermilab. The integrated luminosity of the data set is 140 pb{sup -1} and a total of four candidate events are seen, with an expected background of 2.61 events. The measured cross section of {sigma}{sub t{bar t}} = 11.1{sub -9.3}{sup +22.1}(stat.){sub -4.5}{sup +4.3}(sys.) pb is in agreement with a NNLO calculation of 6.77 pb.

The Production Cross Sections of the Weak Vector Bosons in Proton Antiproton Collisions at s**(1/2) = 1.96-TeV and a Measurement of the W Boson Decay Width

Description: The theory that describes the fundamental particle interactions is called the Standard Model, which is a gauge field theory that comprises the Glashow-Weinberg-Salam model [1, 2, 3] of the weak and electromagnetic interactions and quantum chromodynamics (QCD) [4, 5, 6], the theory of the strong interactions. The discovery of the W [7, 8] and Z [9, 10] bosons in 1983 by the UA1 and UA2 collaborations at the CERN p{bar p} collider provided a direct confirmation of the unification of the weak and … more

Baeyer-Villiger Oxidation of 1,7- & 1,9-dibromopentacyclo[5.4.0.02,6.03,10.05,9]undecane-8,11-dione

Description: Baeyer-Villiger oxidation of 1,9-dibromopentacyclo[5.4.0.02,6.03,10.05,9]undecane-8,11-dione (1,9-dibromo-PCU-8,11-dione) was performed by using an excess amount of m-chloroperbenzoic acid (3 equivalents) and resulted in the formation of the corresponding monolactone. The reaction would not proceed to the dilactone stage. The structure of the reaction product was established unequivocally via single crystal X-ray diffraction.

Effects of Whisker-Trimming on GABAA Receptors in S1 Cortex

Description: A number of studies have shown that sensory deprivation is associated with selective decreases in GABA, GAD, and GABA receptors, in deprived areas of visual and somatosensory cortex. Those studies focused on layer 4, a recipient of direct thalamocortical sensory input. However, supragranular layers 2/3 have been recently identified as a major locus of functional plasticity in sensory deprivation and long-term potentiation. To examine whether GABAA receptors in layers 2/3 are affected by sens… more

The evolution of the Sachs electric and magnetic form factors with Q2, the square of the four-momentum transfer, is related to the distribution of charge and magnetization within the nucleon. High precision measurements of the nucleon form factors are essential for stringent tests of our current theoretical understanding of confinement within … more

Tests of Enhanced Leading Order QCD in W Boson plus Jet Production in 1.96-TeV Proton-Antiproton Collisions

Description: The authors have studied the W + {ge} n jets process in Tevatron Run II experiment. The data used correspond to a total integrated luminosity of 72 pb{sup -1} taken from March 2002 through January 2003. The lowest order QCD predictions have been tested with a new prescription of the parton-jet matching, which allows to construct the enhanced LO phase space. According to this procedure, one gets unique results which do not depend on unphysical bias of kinematical cuts to avoid the collinear/infr… more
