In the present work we examine the possibility of detecting light dark matter particles (WIMP) utilizing their possible interactions with the electrons. Employing reasonable theoretical models we evaluate the expected event rates in the following cases: i) For WIMPs in the meV region treating electrons as free and utilizing calorimetric detectors at low temperatures. ii) Detecting recoiling electrons with energy in the eV region ejected out of an atom in the case of WIMPs with a mass more than an order of magnitude heavier than the electron. iii) By observing atomic excitations in the range of 1 meV to 10 eV excitation energy induced by the electron spin interaction in a magnetic field.
In the present work we examine the implications on dark matter searches of the possibility of a partial decay of a neutron into a dark matter particle, slightly lighter than itself. Such a scenario recently proposed is required to bridge the discrepa
A low pressure time projection chamber for the detection of WIMPs is discussed. Discrimination against Compton electron background in such a device should be very good, and directional information about the recoil atoms would be obtainable. If a full
We explore the phenomenology of a model of monopolium based on an electromagnetic dual formulation of Zwanziger and lattice gauge theory. The monopole is assumed to have a finite-sized inner structure based on a t Hooft-Polyakov like solution, with t
The fine-structure constant and the electron mass in string theory are determined by the values of scalar fields called moduli. If the dark matter takes on the form of such a light modulus, it oscillates with a frequency equal to its mass and an ampl
The discovery of a 125 GeV Higgs boson at the Large Hadron Collider strongly motivates direct searches for additional Higgs bosons. In a type I two Higgs doublet model there is a large region of parameter space at $tanbeta > 5$ that is currently unco
