چکیده
Motivated by the recently observation of tetraquark Tcc+ state, in this work I revisit Heavy-Meson Effective Theory to perform a simplified field-theoretical study possible deuteron-like D(⁎)D(⁎),B¯(⁎)B¯(⁎) and D(⁎)B¯(⁎) molecules. In particular, using data from as input fix potential associated shallow-bound DD⁎ system with I(JP)=0(1+), conditions for formation other loosely-bound states doubly charmed sector are analyzed. The sectors also discussed.

A Note on Quantum Hamming Bound
Quantum stabilizer codes are a known class of quantum codes that can protect quantum information against noise and decoherence. Stabilizer codes can be constructed from self-orthogonal or dualcontaining classical codes, see for example [3, 8, 11] and references therein. It is desirable to study upper and lower bounds on the minimum distance of classical and quantum codes, so the computer search...
متن کاملNote on Bound States and the Bekenstein Bound
In this brief note we draw attention to examples of quantum field theories which may hold interesting lessons for attempts to devise a precise formulation of the Bekenstein bound. Our comments mirror the recent results of Bousso (hep-th/03110223) indicating that the species problem remains an issue for precise formulations of this bound.

هدف از انجام این مطالعه ، بررسی اثرات استفاده از استراتژی های شناختی یعنی "نت برداری" و "زیر خط کردن" بر روی عملکرد درک مطلب زبان آموزان ایرانی می باشد. به این منظور، 60 زبان آموز دختر سال چهارم دبیرستان از طریق آزمون پیشرفت زبان انگلیسی (نلسون)، از یک جامعه آماری بزرگتر انتخاب شدند. سپس به صورت تصادفی به سه گروه که هر گروه شامل ?0 دانش آموز همسان بود، تقسیم شدند: دو گروه آزمایش(گروه "نت برداری...
15 صفحه اولA note on Atanassov’s discrepancy bound for the Halton sequence
In this note, we provide a complete proof of the results presented by E. Atanassov in a 2004 paper about the discrepancy of the Halton sequence. Our proof addresses an inaccuracy found in the original proof, and fills in some non-trivial gaps.
متن کاملA Note on the Intrinsic Cramer-Rao Bound
We consider the intrinsic version of the Cramer-Rao lower bound (CRLB) as introduced by S.T. Smith in 2005. In the concerned paper, the derived lower bound on the intrinsic root-mean-square error (RMSE) of any sample covariance matrix (SCM) estimator is shown not to depend on the underlying parameter, and the author claims the result stems from the invariances of the Fisher Information Metric (...
