Is nonperturbative inflatino production during preheating a real threat to cosmology?

چکیده
We discuss toy models where supersymmetry is broken due to a nonvanishing time-varying vacuum expectation value of the inflaton field during preheating. We discuss the production of an inflatino, the superpartner of the inflaton, due to vacuum fluctuations and then we argue that they do not survive until nucleosynthesis and decay along with the inflaton to produce a thermal bath after preheating. Thus the only relevant remnant which has any significance to be constrained from nucleosynthesis is the helicity 63/2 gravitinos.

Is inflatino production duirng preheating a threat to nucleosynthesis?
We discuss the production of inflatino the superpartner of the inflaton due to vacuum fluctuations during preheating and argue that they do decay alongwith the inflaton to produce a thermal bath. Therefore they do not survive until nucleosynthsis to pose a threat to it. 1 presented the talk, based on the work in Ref. [13].
متن کاملCosmology with orthogonal nilpotent superfields
The MIT Faculty has made this article openly available. Please share how this access benefits you. Your story matters. We study the application of a supersymmetric model with two constrained supermultiplets to inflationary cosmology. The first superfield S is a stabilizer chiral superfield satisfying a nilpotency condition of degree 2, S 2 ¼ 0. The second superfield Φ is the inflaton chiral sup...
متن کاملMagnetic field production during preheating at the electroweak scale.
We study the generation of magnetic fields during preheating within a scenario of hybrid inflation at the electroweak scale. We find that the nonperturbative and strongly out-of-equilibrium process of generation of magnetic fields with a nontrivial helicity occurs along the lines predicted by Vachaspati many years ago. The magnitude (rho_{B}/rho_{EW} approximately 10{-2}) and correlation length...
متن کاملNonthermal production of gravitinos and inflatinos in the Inflationary Universe
The success of primordial nucleosynthesis imposes stringent bounds on the abundance of gravitational relics. This is particularly true for gravitinos, which for models with gravitationally mediated supersymmetry breaking are expected to have a mass below the TeV scale and thus to decay only after nucleosynthesis has concluded. We discuss the nonthermal production of gravitinos in models with se...
متن کاملPatterns from Preheating
The formation of regular patterns is a well-known phenomenon in condensed matter physics. Systems that exhibit pattern formation are typically driven and dissipative with pattern formation occurring in the weakly nonlinear regime and sometimes even in more strongly nonlinear regions of parameter space. In the early universe, parametric resonance can drive explosive particle production called pr...
