DEVELOPMENT IN STRING THEORY
The string theory is a fast moving subject, both physics wise and in the respect of mathematics. In order to keep up with the discipline it is important to move with new ideas which are being stressed. Here I wish to give extracts from new papers of ideas which I have recently found interesting. There are six papers which are involved: I ."Strings formulated directly in 4 dimensions " A. N...
متن کاملNoyes BIT - STRING SCATTERING THEORY
We construct discrete space-time coordinates separated by the Lorentz-invariant intervals h/me in space and h/mc2 in time using discrimination (XOR) between pa?rs of independently generated bit-strings; we prove that if this space is homogeneous and isotropic, it can have only 1, 2 or 3 spatial dimensions once we have related time to a global ordering operator. On this space we construct exact ...
متن کاملOn the Compton Scattering in String Theory
We explicitly compute the Compton amplitude for the scattering of a photon and a (massless) “electron/positron” at tree level and one loop, in a four-dimensional fermionic heterotic string model. We comment on the relationship between the amplitudes we compute in string theory and the corresponding ones in field theory. CERN-TH/97-212 August, 1997
متن کاملU-duality Between NCOS Theory and Matrix Theory
We show that the NCOS (noncommutative open string) theories on torus T p (p ≤ 5) are U-dual to matrix theory on torus with electric flux background. Under U-duality, the number of D-branes and the number of units of electric flux get interchanged. Furthermore under the same U-duality the decoupling limit taken in the NCOS theory maps to the decoupling limit taken in the matrix theory, thus ensu...
متن کاملsuperstring scatterng from dbranes and wess zumino terms in string theory
دو هدف را برای انجام این پایان نامه دنبال می کنیم . نشان می دهیم که بسط دامنه پراکندگی یک میدان راموند-راموند دو میدان پیمانه ای و یک میدان تاکیونی caat بسط سازگاری است که این نکته بیانگر آنست که بسط تاکیونها که بسط انرژی پایین نیست را یافته ایم و این بسط با بسط aatt,ctta,cta,cttt سازگار است با مقایسه با دامنه پراکندگی تعدادی از تصحیحات کنشهای tachyonic dbi, wess-zumino را می یابیم .
