TL;DR: The decoupling limit of the D1-D5 system compactified on T4? S1 has a rich spectrum of U(1) charged excitations as mentioned in this paper, and a detailed analysis of the global identifications of the moduli space yields a picture of multiple weak coupling limits - one for each factorization of N into D1 and D5 charges d1 and d5 = N/d1 - joined through regions of strong coupling in the CFT moduli spaces.
Abstract: The decoupling limit of the D1-D5 system compactified on T4 ? S1 has a rich spectrum of U(1) charged excitations. Even though these states are not BPS in the limit, BPS considerations determine the mass and the semiclassical entropy for a given charge vector. The dependence of the mass formula on the compactification moduli situates the symmetric orbifold SymN(T4) ? 4 conformal field theory in the moduli space. A detailed analysis of the global identifications of the moduli space yields a picture of multiple weak-coupling limits - one for each factorization of N into D1 and D5 charges d1 and d5 = N/d1 - joined through regions of strong coupling in the CFT moduli space.

TL;DR: In this paper, the radiative SU(2) × U(1) breaking induced by broken N = 1 supergravity in the light of recent experimental results is examined. But the experimental results (t-quark mass) constrain the supergravity parameters, particularly the bare higgsino mass μ0 and the mixing Higgs mass term μ32.

TL;DR: In this article, the error of a mass formula is defined in a rigorous way, which leads naturally to the use of experimental uncertainties and of the maximum-likelihood method to derive a set of equations for estimating the parameters and error of the theoretical model.

TL;DR: In this paper, the authors presented 5563 nuclear mass excesses of nuclei beyond the 1 p shell, calculated from the semi-empirical shell-model mass equation of Liran and Zeldes.
