Signals of Leptophilic Dark Matter at the ILC
Adopting a model independent approach, we constrain the various effective
interactions of leptophilic DM particle with the visible world from the WMAP
and Planck data. The thermally averaged indirect DM annihilation cross-section
and the DM-electron direct-detection cross-section for such a DM candidate are
observed to be consistent with the respective experimental data.
We study the production of cosmologically allowed leptophilic DM in
association with , at the ILC.
We perform the analysis and compute the 99\% C.L. acceptance contours
in the and plane from the two dimensional differential
distributions of various kinematic observables obtained after employing parton
showering and hadronization to the simulated data. We observe that the dominant
hadronic channel provides the best kinematic reach of 2.62 TeV ( = 25
GeV), which further improves to 3.13 TeV for polarized beams at
TeV and an integrated luminosity of 1 ab.Comment: 17 pages, 10 figures, 5 table
Spin- portal induced Dark Matter
Standard model (SM) spin-zero singlets are constrained through their
di-Bosonic decay channels via an effective coupling induced by a vector-like
quark (VLQ) loop at the LHC for = 13 TeV. These spin-zero resonances
are then considered as portals for scalar, vector or fermionic dark matter
particle interactions with SM gauge bosons. We find that the model is validated
with respect to the observations from LHC data and from cosmology, indirect and
direct detection experiments for an appreciable range of scalar, vector and
fermionic DM masses greater than 300 GeV and VLQ masses 400 GeV,
corresponding to the three choice of portal masses 270 GeV, 500 GeV and 750 GeV
respectively.Comment: 28 pages, 13 figures, and 2 table
