Covariant Theory of Asymptotic Symmetries, Conservation Laws and Central Charges
, 2001
"... Under suitable assumptions on the boundary conditions, it is shown that there is a bijective correspondence between non trivial asymptotic reducibility parameters and non trivial asymptotically conserved n 2 forms in the context of Lagrangian gauge theories. The asymptotic reducibility parameters ar ..."

and for the existence of a Lie algebra g among equivalence classes of asymptotic reducibility parameters are given. The representation of g in terms of the charges may be centrally extended. An explicit and covariant formula for the central charges is constructed. They are shown to be 2cocycles on the Lie algebra g
TWISTORIAL SUPERPARTICLE WITH TENSORIAL CENTRAL CHARGES 1
, 2001
"... A twistorial formulation of the N = 1 D = 4 superparticle with tensorial central charges describing massive and massless cases in uniform manner is given. The twistors resolve energymomentum vector whereas the tensorial central charges are written in term of spinor Lorentz harmonics. The model make ..."

"... The spectrum of the bosonic sector of the D = 11 Supermembrane with central charges is shown to be discrete with finite multiplicity, hence containing a mass gap. This result extends to the exact theory our previous proof of a similar result for the SU(N) regularized model. Based on these and other ..."

Rational vertex operator algebras and the effective central charge
"... We establish that the Lie algebra of weight one states in a (strongly) rational vertex operator algebra is reductive, and that its Lie rank l is bounded above by the effective central charge ˜c. We show that lattice vertex operator algebras may be characterized by the equalities ˜c = l = c, and in p ..."

N = 2 Rigid Supersymmetry with Gauged Central Charge
, 1998
"... We develop a general setting for N = 2 rigid supersymmetric field theories with gauged central charge in harmonic superspace. We consider those N = 2 multiplets which have a finite number of offshell components and exist off shell owing to a nontrivial central charge. This class includes, in parti ..."

QUANTUM MASS AND CENTRAL CHARGE OF SUPERSYMMETRIC MONOPOLES
, 2006
"... Abstract: We calculate the oneloop quantum corrections to the mass and central charge of N = 2 and N = 4 supersymmetric monopoles in 3+1 dimensions. The corrections to the N = 2 central charge are finite and due to an anomaly in the conformal central charge current, but they cancel for the N = 4 mo ..."

Duality and Central Charges in Supersymmetric Quantum Mechanics
, 2003
"... We identify a class of pointparticle models that exhibit a targetspace duality. This duality arises from a construction based on supersymmetric quantum mechanics with a nonvanishing central charge. Motivated by analogies to string theory, we are led to speculate regarding mechanisms for restricti ..."

CENTRAL CHARGE FOR AdS2 QUANTUM GRAVITY
, 803
"... Twodimensional Maxwelldilaton quantum gravity on AdS2 with radius ℓ and a constant electric field E is studied. In conformal gauge, this is equivalent to a CFT on a strip. In order to maintain consistent boundary conditions, the usual conformal diffeomorphisms must be accompanied by a certain U(1) ..."
