TL;DR: In this article, the bound states of D-p-branes and D-(p+2)-branes with magnetic fields were studied and a perturbative analysis in an expansion in inverse powers of F was presented.
Abstract: We study bound states of D-p-branes and D-(p+2)-branes. By switching on a large magnetic field F on the (p+2) brane, the problem is shown to admit a perturbative analysis in an expansion in inverse powers of F. It is found that, to the leading order in 1/F, the quartic potential of the tachyonic state from the open string stretched between the p- and (p+2)-brane gives a vacuum energy which agrees with the prediction of the BPS mass formula for the bound state. We generalize the discussion to the case of m p-branes plus 1 (p+2)-brane with magnetic field. The T dual picture of this, namely several (p+2)-branes carrying some p-brane charges through magnetic flux is also discussed, where the perturbative treatment is available in the small F limit. We show that once again, in the same approximation, the tachyon condensates give rise to the correct BPS mass formula. The role of 't Hooft's toron configurations in the extension of the above results beyond the quartic approximation as well as the issue of the unbroken gauge symmetries are discussed. We comment on the connection between the present bound state problem and Kondo-like problems in the context of relevant boundary perturbations of boundary conformal field theories.

TL;DR: The first nuclear mass table based entirely on microscopic interactions is presented in this article, where the 9 parameters of the underlying Skyrme and δ-function pairing forces are fitted to all 1492 mass data for A ⩾ 36; the r.m.s. error of this fit is 0.730 MeV.

TL;DR: In this paper, a method of the event reconstruction based on the parton level dynamics is formulated, and the mass probability for the 2→2 processes where 0 or 1 missing particles per channel are included in the final states.
Abstract: A method of the event reconstruction based on the parton level dynamics is formulated. Formulae for the mass probability are given for the 2→2 processes where 0 or 1 missing particles per channel are included in the final states. Uncertainties of the final parton momenta and their propagation to the reconstructed intermediate states are integrated into the formulation. An application to analysis of the top quark pair production with standard decay modes is discussed.
