Searching for B°s [to] J/ψ with the collider detector at Fermilab
This thesis describes a detailed research for the decay B°s (r) J/ψh, within data taken from p collisions at √s=1.8TeV. Proton anti-proton collisions contain many different physics processes. From these processes many are of lesser interest. The trigger logic specific to selecting a sample of data …

Measurement of sin2̳[theta]W̳ from the forward-backward asymmetry in pp̳ [bar] [right arrow] Z0 [right arrow] e+̳e-̳ interactions at [square root]s = 1.8 TeV
… asymmetry in Z0 decays using data from the Collider Detector at Fermilab provides a measurement of sin2 Ow. The forward-backward asymmetry is measured to be (5.2 ± 5.9 (stat)± 0.4 (sys))%, which implies sin2 Ow= 0.228:!8:8G (stat)± 0.002 (sys), after QCD, QED, and weak corrections. vVhen …

Direct Photon Differential Cross Section in p̄p Collisions at the Square Root of s = 1.8 TeV
<p>Data taken from the Collider Detector at Fermilab (CDF) during the 1992-1993 run are used to measure the cross section for production of isolated prompt photons in p̄p collisions at √s = 1.8 TeV. Prompt photon production in p̄p collisions is sensitive to the gluon structure function of the …

Measurement of transverse single-spin asymmetries in π0 and η Meson production in √s = 200 GEV p↑ + p collisions with sPHENIX
The sPHENIX experiment is a next-generation collider detector at the Relativistic Heavy Ion Collider (RHIC) designed for rare jet and heavy-flavor probes of Au + Au, p + Au, and polarized p + p collisions. The experiment includes a large acceptance, granular electromagnetic calorimeter and very …

Detectors and Physics at a Future Linear Collider
An electron-positron linear collider is an option for future large particle accelerator projects. Such a collider would focus on precision tests of the Higgs boson properties. This thesis describes three studies related to the optimisation of highly granular calorimeters and one study on the …

Measurement of the Diffractive Structure Function of the Antiproton in Proton-Antiproton Collisions at √s = 1800 and 630 GeV
… events were collected during the Tevatron collider run of 1995—1996 using the Collider Detector at Fermilab (CDF) by triggering on a leading antiproton detected in a forward Roman Pot spectrometer. From these samples, single diffractive dijet subsamples were selected by requiring two or …
