Third Law of Black-Hole Dynamics: A Formulation and Proof: This paper formulates and proves a precise version of the third law for black holes. A proof of the Zeroth Law can be found in Wald, GR, pp. 333-334.
The String Landscape, Black Holes and Gravity as the Weakest Force: This is a paper which says something interesting about arbitrarily-weakly-gauged symmetries and black holes.
UV/IR Relations in AdS Dynamics: This paper has some thoughtful discussion of the relationship between the radial coordinate of AdS and various energy scales in the field theory.
Aspects of Large N Gauge Theory Dynamics as seen by String Theory (section 4) and All-Genus Calculation of Wilson Loops using D-branes: These two papers describe bulk calculations of Wilson loops in representations other than the fundamental.
Scale and Conformal Invariance in Quantum Field Theory: This is the Polchinski paper about the relation between scale invariance and conformal invariance.
Pointlike Structures Inside and Outside Hadrons: Coleman's `1/N' paper (PDF - 1.3 MB)#
Introduction to Conformal Invariance: Callan's review of conformal symmetry in QFT
Supersymmetry and Non-perturbative Beta Functions: This is a non-perturbative proof of the vanishing of the beta function of the N=4 SYM theory (PDF)#
Comments on Higher Derivative Operators in Some SUSY Field Theories: This is a discussion of a nonzero supersymmetric higher-dimension correction to the effective action.
The Weinberg-Witten Theorem on Massless Particles: This is a review of the Weinberg-Witten theorem.
Topics in Particle Physics and Cosmology Beyond the Standard Model: Alejandro Jenkins' thesis, chapter 2, is another review of the Weinberg-Witten theorem.
