Unified Halo-Independent Formalism From Convex Hulls for Direct Dark Matter Searches
Graciela B. Gelmini, Ji-Haeng Huh, Samuel J. Witte
Using the Fenchel-Eggleston theorem for convex hulls (an extension of the Caratheodory theorem), we prove that any likelihood can be maximized by either a dark matter 1- speed dist…
Assessing Compatibility of Direct Detection Data: Halo-Independent Global Likelihood Analyses
Graciela B. Gelmini, Ji-Haeng Huh, Samuel J. Witte
We present two different halo-independent methods to assess the compatibility of several direct dark matter detection data sets for a given dark matter model using a global likelih…
Extended Maximum Likelihood Halo-independent Analysis of Dark Matter Direct Detection Data
Graciela B. Gelmini, Andreea Georgescu, Paolo Gondolo +1
We extend and correct a recently proposed maximum-likelihood halo-independent method to analyze unbinned direct dark matter detection data. Instead of the recoil energy as independ…
Reevaluation of spin-dependent WIMP-proton interactions as an explanation of the DAMA data
Eugenio Del Nobile, Graciela B. Gelmini, Andreea Georgescu +1
We reexamine the interpretation of the annual modulation signal observed by the DAMA experiment as due to WIMPs with a spin-dependent coupling mostly to protons. We consider both a…
Update on the Halo-Independent Comparison of Direct Dark Matter Detection Data
Eugenio Del Nobile, Graciela B. Gelmini, Paolo Gondolo +1
We briefly review the halo-independent formalism, that allows to compare data from different direct dark matter detection experiments without making assumptions on the properties o…
Direct Detection of Light "Ge-phobic" Exothermic Dark Matter
Graciela B. Gelmini, Andreea Georgescu, Ji-Haeng Huh
We present comparisons of direct dark matter (DM) detection data for light WIMPs with exothermic scattering with nuclei (exoDM), both assuming the Standard Halo Model (SHM) and in…
Direct detection of Light Anapole and Magnetic Dipole DM
Eugenio Del Nobile, Graciela B. Gelmini, Paolo Gondolo +1
We present comparisons of direct detection data for "light WIMPs" with an anapole moment interaction (ADM) and a magnetic dipole moment interaction (MDM), both assuming the Standar…
Update on Light WIMP Limits: LUX, lite and Light
Eugenio Del Nobile, Graciela B. Gelmini, Paolo Gondolo +1
We reexamine the current direct dark matter data including the recent CDMSlite and LUX data, assuming that the dark matter consists of light WIMPs, with mass close to 10 GeV/…
Generalized Halo Independent Comparison of Direct Dark Matter Detection Data
Eugenio Del Nobile, Graciela Gelmini, Paolo Gondolo +1
We extend the halo-independent method to compare direct dark matter detection data, so far used only for spin-independent WIMP-nucleon interactions, to any type of interaction. As…
Complementarity of dark matter direct detection: the role of bolometric targets
D. G. Cerdeno, C. Cuesta, M. Fornasa +9
We study how the combined observation of dark matter in various direct detection experiments can be used to determine the phenomenological properties of WIMP dark matter: mass, spi…
Halo-independent analysis of direct detection data for light WIMPs
Eugenio Del Nobile, Graciela B. Gelmini, Paolo Gondolo +1
We present a halo-independent analysis of direct detection data on "light WIMPs," i.e. weakly interacting massive particles with mass close to or below 10 GeV/c^2. We include new r…
Asymmetric dark matter annihilation as a test of non-standard cosmologies
Graciela B. Gelmini, Ji-Haeng Huh, Thomas Rehagen
We show that the relic abundance of the minority component of asymmetric dark matter can be very sensitive to the expansion rate of the Universe and the temperature of transition b…
Nuclear uncertainties in the spin-dependent structure functions for direct dark matter detection
David G. Cerdeno, Mattia Fornasa, Ji-Haeng Huh +1
We study the effect that uncertainties in the nuclear spin-dependent structure functions have in the determination of the dark matter (DM) parameters in a direct detection experime…
Halo independent comparison of direct dark matter detection data
Paolo Gondolo, Graciela B. Gelmini
We extend the halo-independent method of Fox, Liu, and Weiner to include energy resolution and efficiency with arbitrary energy dependence, making it more suitable for experiments…
Very light right-handed sneutrino dark matter in the NMSSM
David G. Cerdeno, Ji-Haeng Huh, Miguel Peiro +1
Very light right-handed (RH) sneutrinos in the Next-to-Minimal Supersymmetric Standard Model can be viable candidates for cold dark matter. We investigate the prospects for their d…
Constraining WIMP magnetic moment from CDMS II experiment
Won Sang Cho, Ji-Haeng Huh, Ian-Woo Kim +2
We consider a degenerate or a nearly degenerate dark matter sector where a sizable magnetic moment of an almost Dirac type neutral dark matter candidate N is anticipated. Then, due…
Decaying dark matter with heavy axino
Ji-Haeng Huh, Jihn E. Kim
A TeV scale decaying dark matter chiral multiplet N is introduced in addition to the minimal supersymmetric standard model(MSSM). For a calculable abundance of N, we introduce heav…

Ji-Haeng Huh, Jihn E. Kim, Bumseok Kyae
Based on the Z_{12-I} orbifold compactification of the heterotic string theory, we construct a flipped-SU(5) model with three families of the standard model matter and ingredients…

White dwarf axions, PAMELA data, and flipped-SU(5)
Kyu Jung Bae, Ji-Haeng Huh, Jihn E. Kim +2
Recently, there are two hints arising from physics beyond the standard model. One is a possible energy loss mechanism due to emission of very weakly interacting light particles fro…
