Spatial Compactification and Decay-Rate Behaviour
نویسندگان
چکیده
The transition from instanton-dominated quantum tunneling regime to sphaleron-dominated classical crossover regime is explored in (1+1)dimensional scalar field theory when spatial coordinate is compactified. It is shown that the type of sphaleron transition is critically dependent on the circumference of the spatial coordinate.

Long Lived Large Type II Strings: decay within compactification
Motivated also by recent revival of interest about metastable string states (as cosmic strings or in accelerator physics), we study the decay, in presence of dimensional compactification, of a particular superstring state, which was proven to be remarkably long-lived in the flat uncompactified scenario. We compute the decay rate by an exact numerical evaluation of the imaginary part of the one-...
متن کاملAsymptotics of Radiation Fields in Asymptotically Minkowski Space
We consider a non-trapping n-dimensional Lorentzian manifold endowed with an end structure modeled on the radial compactification of Minkowski space. We find a full asymptotic expansion for tempered forward solutions of the wave equation in all asymptotic regimes. The rates of decay seen in the asymptotic expansion are related to the resonances of a natural asymptotically hyperbolic problem on ...
متن کاملThe Fate of Massive Closed Strings
We calculate the semi-inclusive decay rate of an average string state with toroidal compactification in the the superstring theory. We also apply this calculation to a brane-inflation model in a warped geometry and find that the decay rate is greatly suppressed if the final strings are both massive and enhanced for massless radiation.
متن کاملThe Fate of Massive F-Strings
We calculate the semi-inclusive decay rate of an average string state with compactification both in the bosonic string theory and in the superstring theory. We also apply this calculation to a brane-inflation model in a warped geometry and find that the decay rate is greatly suppressed if final strings are all massive and enhanced with one final string massless, which may pose a challenge to th...
متن کاملHiggs Boson Decay Rate into Gluons in a 5 Dimensional Calculable Model
In an extension of the Standard Model with one compact extra dimension and N=1 supersymmetry, we compute the Higgs boson decay width into two gluons, relevant to the Higgs production in hadronic collisions. We find that at one-loop the decay width is significantly suppressed with respect to the SM. In particular, for a compactification radius R = (370 ± 70GeV ) and a Higgs mass mH = 127 ± 8GeV ...
