Dark Matter with Topological Defects in the Inert Doublet Model
We examine the production of dark matter by decaying topological defects in the high mass region mDM mW of the Inert Doublet Model, extended with an extra U(1) gauge symmetry. The density of dark matter states (the neutral Higgs states of the inert doublet) is determined by the interplay of the freeze-out mechanism and the additional production of dark matter states from the decays of topologic...
متن کاملNeutrinos from Inert Doublet Dark Matter
We investigate the signatures of neutrinos produced in the annihilation of WIMP dark matter in the Earth, the Sun and at the Galactic centre within the framework of the Inert Doublet Model and extensions. To accommodate the WMAP constraints, the dark matter candidate, which is one of the neutral components of an extra Higgs doublet, must have a mass in either one of three distinct mass ranges: ...
متن کاملRealistic Vehicular Mobility Impact of FTM, IDM, IDM-IM and IDM-LC on VANETs
VANETs are composed of a number of vehicles moving on city roads, able to interconnect with one another without a fixed infrastructure. Improvisation of a new vehicular communication system should entitle a node to travel safely with high speed mobility while maintaining seamless interconnectivity. To evaluate the impact of mobility models such as FTM, IDM, IDM-IM and IDM-LC on VANETs routing p...
متن کاملRestricting the IDM for Classification
The naive credal classifier (NCC) extends naive Bayes classifier (NBC) to imprecise probabilities to robustly deal with the specification of the prior; NCC models a state of ignorance by using a set of priors, which is formalized by Walley’s Imprecise Dirichlet Model (IDM). NCC has been shown to return more robust classification than NBC. However, there are particular situations (which we preci...
متن کاملLow Energy Gamma Ray Excess Confronting a Singlet Scalar Extended Inert Doublet Dark Matter Model
Recent study of gamma rays originating from the region of galactic centre has confirmed an anomalous γ-ray excess within the energy range 1-3 GeV. This can be explained as the consequence of pair annihilation of a 31-40 GeV dark matter into bb̄ with thermal annihilation cross-section σv ∼ 1.4 − 2.0 × 10−26 cm/s. In this work we revisit the Inert Doublet Model (IDM) in order to explain this gamma...
