Space-Time Structure of Weak and Electromagnetic Interactions
It has often been suggested that observed symmetries among elementary particles may well reflect symmetries of some fundamental dynamical equation or system of equations. The suggestion has gained credence with the recent successes of gauge theories, the WeinbergSalam (W-S) model in particular. However, in current theories no definite connection has yet been established between the so-called in...
متن کاملWeak and Electromagnetic Interactions
The postulate of a <( local eonnection~) in a [3] charge space leads to the introduction of three spin one fields. One of these can be identified with the electro-magnetic field and the other two can be shown to mediate all known weak interactions, thus unifying these interactions with electro-magnetism. The theory takes account of the fact that weak interactions violate parity and strangeness ...
متن کاملthe underlying structure of language proficiency and the proficiency level
هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
15 صفحه اولSargent plot , weak interactions , and the geometry of the flat space - time
Sargent plot, summarizes part of one of the pioneers experiments on nuclear beta decay. Here it is proposed to be used as a motivation, to teach undergraduate students some basic features of the weak interactions. This is done by considering only elementary aspects of special relativity and quantum theories. 1 – Introduction It has been elapsed a time interval of eighty years, since B. W. Sarge...
متن کاملStructure of the Nucleon from Electromagnetic Space-like and Time-like Form Factors
Recent experimental data on space-like and time-like form factors of the nucleon are reviewed in light of a model of the nucleon with an intrinsic (quark-like) structure and a meson cloud. The analysis points to the astonishing result that the proton electric space-like form factor vanishes at Q ∼ 8 (GeV/c) and becomes negative beyond that point. The intrinsic structure is estimated to have a r...
