Physical Review D, 2021 A new $U(1)$ dark gauge group coupled to the Standard Model (SM) via the kinetic mixing portal provides a natural dark matter candidate in the form of the Higgs field, $h_d$, responsible for generating the mass of the dark photon, $ _d$. We show that the condition $m_{h_d}\leq m_{ _d}$, together with smallness of the kinetic mixing parameter ...

International Journal of Modern Physics D, 2004 Extra-dimensional theories contain additional degrees of freedom related to the geometry of the extra space which can be interpreted as new particles. Such theories allow to reformulate most of the fundamental problems of physics from a completely different point of view.

Effect of photoperiod on somatic embryogenesis in different organs of chickpea (Cicer arietinum L.) [PDF]
پژوهشهای حبوبات ایران, 2016 Introduction Somatic embryogenesis is an efficient platform for the generation of transgenic plants and synthetic seeds (Kiran et al., 2005). Somatic embryo’s growth and development were influenced by different factors, including photoperiod, genotype as

Angular Momentum of Topologically Structured Darkness. [PDF]
Physical Review Letters, 2017 We theoretically analyze and experimentally measure the extrinsic angular momentum contribution of topologically structured darkness found within fractional vortex beams, and show that this structured darkness can be explained by evanescent waves at ...

Physics Letters B, 2019 The paper brings a novel approach to unification of dark matter and dark energy in terms of a cosmic fluid. A model is introduced in which the cosmic fluid speed of sound squared is defined as a function of its equation of state (EoS) parameter. It is shown how logarithmic part of this function results in dynamical regimes previously not observed in ...
