Optical theorem and effective action: new proofs of old results in QFT
Sergio L. Cacciatori, Andrea Zanzi
A new proof of the optical theorem at all orders is presented. Although the theorem is a well-known result in Quantum Field Theory, our proof is interesting because it is particula…
Quantum mechanics before the big bang in heterotic-M-theory
Andrea Zanzi
In this letter we investigate the role played by quantum mechanics before the big-bang in heterotic-M-theory assuming an orbifold compactification of time. As we will see particles…
The cosmological constant problem in heterotic-M-theory and the orbifold of time
Andrea Zanzi
Chameleon fields are quantum fields with an increasing mass as a function of the matter density of the environment. Recently chameleon fields have been exploited to solve the cosmo…
Dilaton stabilization and composite dark matter in the string frame of heterotic-M-theory
Andrea Zanzi
In this paper we further elaborate on our recently proposed solution to the cosmological constant problem - Phys. Rev. D82 (2010) 044006. One of the elements of the solution is the…
Species, chameleonic strings and the concept of particle
Andrea Zanzi
We recently proposed a chameleonic solution to the cosmological constant problem - Phys. Rev. D82 (2010) 044006. We further elaborate on our proposal discussing also some new resul…
Chameleonic dilaton and conformal transformations
Andrea Zanzi
We recently proposed a chameleonic solution to the cosmological constant problem - Phys. Rev. D82 (2010) 044006. One of the results of that paper is a non-equivalence of different…
