Can the Inflaton Also Be a Weakly Interacting Massive Particle?

Can MSSM Particle be the Inflaton?

We consider the possibility of using one of the D-flat directions in the minimal supersymmetric standard model (MSSM) as the inflaton. We show that the flat direction consisting of (first generation) leftand right-handed up-squarks as well as the up-type Higgs boson may play the role of the inflaton if dominant part of the up-quark mass is radiatively generated from supersymmetric loop diagrams...

Generalized analysis of the direct weakly interacting massive particle searches

We perform a generalized analysis of data from WIMP search experiments for pointlike WIMPs of arbitrary spin and general Lorenz-invariant WIMP-nucleus interaction. We explicitly show that in the nonrelativistic limit only spin-independent ~SI! and spin-dependent ~SD! WIMP-nucleon interactions survive, which can be parametrized by only five independent parameters. We explore this five-dimensiona...

On the direct detection of extragalactic weakly interacting massive particles

We consider the direct detection of weakly interacting massive particles (WIMPs) reaching the Earth from outside the Milky Way. If these WIMPs form a distinct population they will, although of much lower flux than typical galactic halo WIMPs, have a number of features which might aid in their ultimate detectability: a high and essentially unique velocity (∼ 600 km/s in the galactic rest frame) ...

Recursive Path Orderings Can Also Be Incremental

In this paper the Recursive Path Ordering is adapted for proving termination of rewriting incrementally. The new ordering, called Recursive Path Ordering with Modules, has as ingredients not only a precedence but also an underlying ordering =B. It can be used for incremental (innermost) termination proofs of hierarchical unions by defining =B as an extension of the termination proof obtained fo...
