investigation of effective parameters on the rigidity of light composite diaphragms (psscb) by fem
در این رساله با معرفی سقف های psscb متشکل از ترکیب ورق های فولادی ذوزنقه ای و تخته های سیمانی الیافی به عنوان سقف های پیش ساخته (سازگار با سیستم سازه ای قاب های فولادی سبک) به بررسی پارامترهای موثر بر صلبیت سقف، پرداخته می شود. در تحقیق حاضر ابتدا به مدل سازی دو نمونه سقف آزمایش شده، به روش اجزاء محدود با استفاده از نرم افزار تحلیلی abaqus ver 6.10 پرداخته شده است. نمونه های ساخته شده تحت اعما...
Effective theories and constraints on new physics
Anomalous moments of the top quark arises from one loop corrections to the vertices t̄tg and t̄tγ . We study these anomalous couplings in different frameworks: effective theories, Standard Model and 2HDM. We use available experimental results in order to get bounds on these anomalous couplings.
متن کاملEffective Mass Scale of New Physics in the Absence of the Higgs Boson
We consider a hypothetical scenario in which the Higgs boson is absent, and attempt to constrain the effective mass scaleMNP of the new physics that would take its place. Characterizing MNP in the simplest manner, we estimate this parameter using recent measurements of sin θ eff and MW . The two determinations of MNP are in good agreement and turn out to be close to current estimates for MH in ...

متن کاملA Tool to Measure New - Physics Parameters
If physics beyond the standard model is present in B decays, experimental measurements seem to suggest that it principally affects those processes with significant b̄ → s̄ penguin amplitudes. It was recently argued that, in general, such new-physics (NP) effects can be parametrized in terms of a single NP amplitudeAq and phase Φq, for q = u, d, s, c. In this paper, we show that the study of the d...
