Representations of the fractional d'Alembertian and initial conditions in fractional dynamics
Gianluca Calcagni, Giuseppe Nardelli
We construct representations of complex powers of the d'Alembertian operator in Lorentzian signature and pinpoint one which is self-adjoint and suitable for classical and qu…
Form factors, spectral and Källén-Lehmann representation in nonlocal quantum gravity
Fabio Briscese, Gianluca Calcagni, Leonardo Modesto +1
We discuss the conical region of convergence of exponential and asymptotically polynomial form factors and their integral representations. Then, we calculate the spectral represent…
A new rolling tachyon solution of cubic string field theory
V. Forini, G. Grignani, G. Nardelli
We present a new analytic time dependent solution of cubic string field theory at the lowest order in the level truncation scheme. The tachyon profile we have found is a bounce in…
Exact potential and scattering amplitudes from the tachyon non-linear -function
E. Coletti, V. Forini, G. Grignani +2
We compute, on the disk, the non-linear tachyon -function, , of the open bosonic string theory. is determined both in an expansion to the third power of the field and…
Scaling properties of the perturbative Wilson loop in two-dimensional non-commutative Yang-Mills theory
A. Bassetto, G. Nardelli, A. Torrielli
Commutative Yang-Mills theories in 1+1 dimensions exhibit an interesting interplay between geometrical properties and U(N) gauge structures: in the exact expression of a Wilson loo…
Perturbative Wilson loop in two-dimensional non-commutative Yang-Mills theory
A. Bassetto, G. Nardelli, A. Torrielli
We perform a perturbative Wilson loop calculation for the U(N) Yang-Mills theory defined on non-commutative one space - one time dimensions. We choose the light-con…
