چکیده

The non-Abelian gauge structure of the Standard Model implies presence multi-boson self-interactions. Precise measurements in experimental and theoretical studies these interactions allow not only testing nature but also new physics contribution coming from beyond Model. These can be examined using a model-independent way effective theory approach that composes motivation part this study. In paper, we examine anomalous ZZγ Zγγ neutral triple couplings via process e−e+→Zγ for neutrino-antineutrino pair decay Z boson. It has performed with both unpolarized polarized electron beams at Compact Linear Collider s=3 TeV. study focused on CP-conserving CB˜W/Λ4 CP-violating CBB/Λ4, CBW/Λ4, CWW/Λ4 couplings. Obtained sensitivities 95% Confidence Level are given systematic uncertainties 0%, 5% 10% unpolarized, −80% 80% integrated luminosities Lint=5 ab−1, Lint=4 ab−1 Lint=1 respectively. Comparing latest limits related phenomenological studies, our results set more stringent sensitivity between 10-30 times magnitude.

the search for the self in becketts theatre: waiting for godot and endgame

this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...

New Higgs Interactions in ZZγ and Zγγ Production

The effect of new operators that only modify the bosonic couplings of the Higgs boson, without altering the WWγ or WWZ three–point functions, are examined in the ee → ZZγ and Zγγ processes. We analyse the constraints on these interactions that can be imposed by the LEP II collider at CERN and at the Next Linear Collider. Typeset using REVTEX

SEARCH FOR ANOMALOUS COUPLINGS AT eγ COLLIDERS

We consider the possibility of observing deviations from the Standard Model gauge-boson self-couplings at future eγ colliders. We concentrate on the process eγ → νWZ, which is particularly sensitive to the parity violating coupling gZ 5 at high energies. We find that a 2 TeV e +e− collider operating in the eγ mode could reach a sensitivity of order 5× 10−3 to gZ 5 .

‏‎faciliting lexical access for the fluent production of speech‎‏

‏‎the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis,a one-way anova experimental design was carried out. 24 sednior students of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inter...
