ON THE HOLOMORPHICALLY FACTORIZED PARTITION FUNCTION FOR ABELIAN GAUGE THEORY IN SIX DIMENSIONS
We use holomorphic factorization to find the partition functions of an Abelian two-form chiral gauge-field on a flat six-torus. We prove that exactly one of these partition functions is modular invariant. It turns out to be the one that previously has been found in a Hamiltonian formulation.

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.

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.

Algebraic structures on parallel M2-branes
Abstract In the course of closing supersymmetry on parallel M2 branes up to a gauge transformation, following the suggestion in [J. Bagger, N. Lambert, Phys. Rev. D 75 (2007) 045020, hep-th/0611108 ] of incorporating a gauge field which only has topological degrees of freedom, we are led to assume a certain algebraic structure for the low energy theory supposedly living on parallel M2 branes.

On the Weyl anomaly of Wilson surfaces
We compute the Weyl anomaly for an abelian Wilson surface by using a regularization that respects the gauge invariance. We then study the loop space on which lives a one-form connection. We restrict ourselves to the subsector consisting of only concentrical circular loops, and derive a Maxwell type action on this restricted loop space.

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.

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.
