Five-dimensional super Yang-Mills theory from ABJM theory
We derive five-dimensional super Yang-Mills theory from mass-deformed ABJM theory by expanding about S2 for large Chern-Simons level K. We obtain the Yang-Mills coupling constant $ g_{Y\;M}^2 = {{{4{\pi^2}R}} \left/ {K} \right.} $. If we consider $ {{{{S^3}}} \left/ {{{\mathbb{Z}_K}}} \right.} $ as a fiber bundle over S2 then R/K is the circumference of the fiber. The value on the coupling constant agrees with what one gets by compactifying M five-brane on that fiber. For this computation we take R, K → ∞ while keeping R/K at a fixed finite value. We also study mass deformed star-three-product BLG theory at K = 1 and R → ∞. In that limit we obtain Lorentz covariant supersymmetry variations and gauge variations of a non-Abelian tensor multiplet.

One dyonic instanton in 5d maximal SYM theory
A bstractWe study the one-instanton sector of 5d U(N) maximal SYM theory. By using the moduli space approximation we obtain all the 1/4-BPS bound states of one dyonic instanton when a vev is given to one of the SYM scalar fields that breaks U(N) maximally. We compute the corresponding 1/4-BPS index and partition function and find agreement with arXiv:1110.2175.

Classical self-dual BPS strings in d=6, (2,0) theory from afar
We show how one can get solitonic strings in a six-dimensional (2,0) supersymmetric theory by incorporating a nonlinear interaction term. We derive a zero force condition between parallel strings, and compute a metric on a moduli space which is R4 when the strings are far apart. When compactifying the strings on a two-torus we show that, in the limit of vanishing two-torus, one regains the moduli space of two widely separated dyons of equal magnetic charges in four dimensions.

One-loop corrections to Bagger–Lambert theory
Abstract We rewrite the Bagger–Lambert action for any Lie 3-algebra as a standard Chern–Simons action coupled to matter. We use this action to compute self-energies and vertex corrections at one-loop order. Non-renormalization of the coupling constant comes out as a direct consequence of the Lie 3-algebra structure underlying the Lie algebra.

A VERY THIN HAVAR FILM VACUUM WINDOW FOR HEAVY IONS TO PERFORM RADIOBIOLOGY STUDIES AT THE BNL TANDEM
Heavy ion beams from the BNL Tandem Van de Graaff accelerators will be made available for radiobiology studies on cell cultures. Beam energy losses need to be minimized both in the vacuum window and in the air in order to achieve the ranges required for the cells to be studied. This is particularly challenging for ions heavier than iron. The design is presented of a 0.4-inch diameter Havar film window that will satisfy these requirements. Films as thin as 80 microinches were successfully pressure tested. The final thickness to be used may be slightly larger to help in achieving pin hole free windows. We discuss design considerations and present pressure and vacuum test results as well as tests with heavy ion beams.
