FPRD and Department of Physics and Astronomy, Seoul National University,Seoul 151-747,, the CoGeNT collaboration reported the WIMP candidate signal events exceeding theknown backgrounds where the light WIMP with large cross section is supported. Motivated bythis issue, we analyze a light neutralino dark matter scenario with a very light CP-even Higgsmediation in the elastic scattering process, which provides the mass and direct detection crosssection to… Expand

Secluded singlet fermionic dark matter driven by the Fermi gamma-ray excess
We examine the possibility that the dark matter (DM) interpretation of the GeV scale Fermi gamma-ray excess at the Galactic center can be realized in a specific framework-secluded singlet fermionicExpand
Implications of CoGeNT's New Results For Dark Matter
The CoGeNT Collaboration has recently presented the results of their first 15 months of data, including the measurement of the spectrum of nuclear recoil candidate events, and the time variation ofExpand
Experimental observations and theoretical arguments at Galaxy and larger scales have suggested that a large fraction of the Universe is composed by Dark Matter particles. This has motivated the DAMAExpand
Flavour physics constraints in the BMSSM
We study the implications of the presence of the two leading-order, non-renormalizable operators in the Higgs sector of the MSSM to flavour physics observables. We identify the constraints of flavourExpand
Beyond the Standard Model physics at the HL-LHC and HE-LHC
This is the third out of five chapters of the final report [1] of the Workshop on Physics at HL-LHC, and perspectives on HE-LHC [2]. It is devoted to the study of the potential, in the search forExpand


Light neutralino dark matter with a very light Higgs boson for CoGeNT and DAMA/LIBRA data
Recently, the CoGeNT collaboration reported weakly interacting massive particle candidate-signal events exceeding the known backgrounds where the light WIMP with large cross section is supported.Expand
CoGeNT, DAMA, and Light Neutralino Dark Matter
Abstract Recent observations by the CoGeNT collaboration (as well as long standing observations by DAMA/LIBRA) suggest the presence of a ∼ 5 – 10 GeV dark matter particle with a somewhat largeExpand
Light scalar WIMP through the Higgs portal and CoGeNT
If dark matter (DM) simply consists in a scalar particle interacting dominantly with the Higgs boson, the ratio of its annihilation cross section---which is relevant both for the relic abundance andExpand
Implications of CoGeNT and DAMA for Light WIMP Dark Matter
In this paper, we study the recent excess of low energy events observed by the CoGeNT Collaboration, and discuss the possibility that these events originate from the elastic scattering of a lightExpand
Neutralino dark matter in BMSSM effective theory
We study thermal neutralino dark matter in an effective field theory extension of the MSSM, called ``Beyond the MSSM'' (BMSSM) in Dine, Seiberg and Thomas (2007). In this class of effective fieldExpand
Light neutralinos with large scattering cross sections in the minimal supersymmetric standard model
Motivated by recent data from CoGeNT and the DAMA annual modulation signal, we discuss collider constraints on the minimal supersymmetric standard model neutralino dark matter with mass in the 5-15Expand
Light Higgs Scenario in BMSSM and LEP Precision Data
In this Letter we consider very light Higgs fields in BMSSM(Beyond MSSM). The spectrum below TeV scale is the same as the MSSM but the Higgs potential is modified and is well described in terms ofExpand
CoGeNT, DAMA, and Neutralino Dark Matter in the Next-To-Minimal Supersymmetric Standard Model
We assess the extent to which the NMSSM can allow for light dark matter in the $2\gev\lsim \mcnone\lsim 12\gev$ mass range with correct relic density and large spin-independent direct-detection crossExpand
Complex Scalar Dark Matter vis-`a-vis CoGeNT, DAMA/LIBRA and XENON100
The CoGeNT and DAMA/LIBRA experiments have found evidence for the spin-independent scattering from nuclei of a light dark matter (DM) particle, 7-12 GeV, which is not excluded by the XENON DMExpand
First dark matter results from the XENON100 experiment.
First dark matter results from the analysis of 11.17 live days of nonblind data are presented, which constrains the interpretation of the CoGeNT and DAMA signals as being due to spin-independent, elastic, light mass WIMP interactions. Expand
