A testable model simultaneously explaining neutrino mass and dark matter

Abstract:Recently a minimalistic scenario has been developed to explain dark matter and tiny but nonzero neutrino masses. In this scenario, a new scalar called SLIM plays the role of the dark matter. Neutrinos achieve Majorana mass through a one-loop diagram. This scenario can be realized for both real and complex SLIM. Simultaneously explaining the neutrino mass and dark matter abundance constrains the scenario. In particular for real SLIM, an upper bound of a few MeV on the masses of the new particles and a lower bound on their coupling are obtained which make the scenario testable. The low energy scenario can be embedded within various SU(2)xU(1) symmetric models. I shall briefly review the scenario and a specific model that embeds the scenario, with special emphasis on the effects in the charged Kaon decay which might be observable at the KLOE and NA62 experiments. I will also discuss the potential of discovering the model at the LHC.

Short CV:
In 1373, I was enrolled in the Physics department of Sharif Univ. In 1377, I completed my undergraduate studies ranking the first in my undergraduate class. In the same year, I participated in the entrance exam of MSc and ranked the first in this exam which was held nationwide. My MS thesis was entitled "Axions in large extra dimensions". After finishing the MSc course, I went to Trieste, Italy and participated in the entrance exam of PhD program at SISSA (International School for Advanced Studies). I was among the eight students who passed the exam. In first year we passed five courses and only in the second year, we started working on our thesis. I chose neutrino physics as my research area. I was lucky enough to be accepted as a student by Prof. A. Yu. Smirnov who is a leading neutrino physicist. After one year, in 1380, my husband got a Post-doc position at Stanford and I accompanied him to the USA. Before going to the USA, we had correspondence with the head of the theory group of Stanford Linear Accelerator Center (SLAC), Prof. Michael Peskin. He encouraged me to complete my thesis as a long term visitor at their institute. While in the USA, I kept in touch with my supervisor and wrote more papers together and at the same time I benefited from the outstanding scientific atmosphere at SLAC. In 1383, we returned to Italy and I defended my thesis. I am currently an associate professor. Since Jan. 2007, I am also a junior associate member of ICTP.
