Precision spectroscopy and higher spin symmetry in the ABJM model

We revisit Kaluza-Klein compactification of 11-d supergravity on S/Zk using group theory techniques that may find application in other flux vacua with internal coset spaces. Among the SO(2) neutral states, we identify marginal deformations and fields that couple to the recently discussed world-sheet instanton of Type IIA on CP3. We also discuss charged states, dual to monopole operators, and th...

the survey of the virtual higher education in iran and the ways of its development and improvement

این پژوهش با هدف "بررسی وضعیت موجود آموزش عالی مجازی در ایران و راههای توسعه و ارتقای آن " و با روش توصیفی-تحلیلی و پیمایشی صورت پذیرفته است. بررسی اسنادو مدارک موجود در زمینه آموزش مجازی نشان داد تعداد دانشجویان و مقاطع تحصیلی و رشته محل های دوره های الکترونیکی چندان مطلوب نبوده و از نظر کیفی نیز وضعیت شاخص خدمات آموزشی اساتید و وضعیت شبکه اینترنت در محیط آموزش مجازی نامطلوب است.

ABJM Dibaryon Spectroscopy

We extend the proposal for a detailed map between wrapped D-branes in Anti-de Sitter space and baryon-like operators in the associated dual conformal field theory provided in hep-th/0202150 to the recently formulated AdS4 × CP/ABJM correspondence. In this example, the role of the dibaryon operator of the 3dimensional CFT is played by a D4-brane wrapping a CP ⊂ CP. This topologically stable D-br...

Higher Spin Symmetry and N = 4 SYM

We assemble the spectrum of single-trace operators in free N = 4 SU (N) SYM theory into irreducible representations of the Higher Spin symmetry algebra hs(2, 2|4). Higher Spin representations or YT-pletons are associated to Young tableaux (YT) corresponding to representations of the symmetric group compatible with the cyclicity of color traces. After turning on interactions g YM = 0, YT-pletons...
