A preliminary test of Abelian D4–M5 duality
Abstract We compute the partition function of five-dimensional Abelian SYM including a graviphoton term on a five-torus. The result agrees with Abelian M5 brane partition function with zero characteristics on an associated six-torus.

Dynamics of a wavy plane Wilson surface observable from AdS-CFT correspondence
Guided by the paper [10] by Polyakov and Rychkov, we compute the second variational derivative of a wavy plane Wilson surface observable, to find that a necessary condition for a proposed surface equation to be satisfied in the large-N limit is that we are in the critical dimension D = 6.

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.

Selfdual strings and loop space Nahm equations
We give two independent arguments why the classical membrane fields should be take values in a loop algebra. The first argument comes from how we may construct selfdual strings in the M5 brane from a loop space version of the Nahm equations. The second argument is that there appears to be no infinite set of finite-dimensional Lie algebras (such as su(N) for any N) that satisfies the algebraic structure of the membrane theory.

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.

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.

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.
