Supersymmetry and T Decays
A brief review of the status of searches for supersymmetry involving the r lepton is given. Introduction Low energy supersymmetry [‘I is an attractive extension of the Standard Model[21131 addressing the problems of divergencies encountered in the theory by introduction of the fermion-boson symmetry. It predicts the existence of partners of all known fundamental particles with the same quantum ...
متن کاملT–duality and World–sheet Supersymmetry
Four–dimensional string backgrounds with local realizations of N = 4 world– sheet supersymmetry have, in the presence of a rotational Killing symmetry, only one complex structure which is an SO(2) singlet, while the other two form an SO(2) doublet. Although N = 2 world–sheet supersymmetry is always preserved under Abelian T–duality transformations, N = 4 breaks down to N = 2 in the rotational c...
متن کاملN = (4, 4) Supersymmetry and T-Duality
A sigma model with four-dimensional target space parametrized by chiral and twisted chiral N =(2, 2) superfields can be extended to N =(4, 4) supersymmetry off-shell, but this is not true for a model of semichiral fields, where the N = (4, 4) supersymmetry can only be realized on-shell. The two models can be related to each other by T-duality. In this paper we perform a duality transformation f...
متن کاملT-Duality and Space-Time Supersymmetry
We analyze in detail the possible breaking of space-time supersymmetry under Tduality transformations. We find that when appropiate world-sheet effects are taken into account apparent puzzles concerning supersymmetry in space-time are solved. We study T-duality in general heterotic σ-models analyzing possible anomalies, and we find some modifications of Buscher’s rules. We then work out a simpl...
متن کاملبررسی کاریوتیپی چهار گونه آویشن (Thymus spp) T. lancifolius) ،T. daenensis ، T. fedtschenkoi و pubescens T.)
آویشن (Thymus) از تیره Lamiaceae گیاهی است چند ساله که به‌دلیل خاصیت دارویی از اهمیت بالایی برخوردار است. بذرهای پنج جمعیت متعلق به چهار گونه T. Lancifolius،T. daenensis subsp. daenensis (دو نمونه)، T. fedtschenkoiو pubescens .Tکشت گردید و پس از جوانه‌زنی بذرها از مریستم انتهایی ریشه برای مطالعات کاریوتیپی استفاده شد. نتایج نشان داد که تعداد کروموزوم پایه در تمام جمعیت‌های مورد بررسی 15= x اس...
