We study the scenario which incorporates dark matter in the minimal left-right symmetric theory at the TeV scale. The only viable candidate is found to be the lightest right-handed neutrino with a mass of keV. In order to satisfy the dark matter relic abundance, the relic yield is diluted by late decays of the two heavier neutrinos. We point out that the QCD phase transition temperature coincidences with the typical freeze-out temperature governed by super-weak right-handed interactions. This… Expand

Keung-Senjanović process at the LHC: From lepton number violation to displaced vertices to invisible decays
In the context of Left-Right symmetry, we revisit the Keung-Senjanovi\'c production of right-handed $W_R$ bosons and heavy neutrinos $N$ at high energy colliders. We develop a multi-binnedExpand
0νββ in left-right theories with Higgs doublets and gauge coupling unification
We consider a version of Left-Right Symmetric Model in which the scalar sector consists of a Higgs bidoublet ($\Phi$) with $B-L=0$, Higgs doublets ($H_{L,R}$) with $B-L=1$ and a charged scalarExpand


Warm dark matter in low scale left-right theory
We investigate the viability of having dark matter in the minimal left-right symmetric theory. We find the lightest right-handed neutrino with a mass around keV as the only viable candidateExpand
First Limits on Left-Right Symmetry Scale from LHC Data
We use the early Large Hadron Collider data to set the lower limit on the scale of Left-Right symmetry, by searching for the right-handed charged gauge boson $W_R$ via the final state with twoExpand
keV sterile neutrino dark matter in gauge extensions of the standard model
It is known, that a keV scale sterile neutrino is a good warm dark matter candidate. We study how this possibility could be realized in the context of gauge extensions of the standard model. TheExpand
Left-right symmetry: from the LHC to neutrinoless double beta decay.
It is shown how the right-handed leptonic mixing matrix, together with constraints from lepton flavor violating processes, can be used to make predictions for neutrinoless double beta decay. Expand

I argue that LHC may shed light on the nature of neutrino mass through the probe of the seesaw mechanism. The smoking gun signature is lepton number violation through the production of same signExpand
Connecting Dirac and Majorana neutrino mass matrices in the minimal left-right symmetric model.
This work addresses the origin of neutrino mass by disentangling the seesaw mechanism in the minimal left-right symmetric model and shows how the knowledge of light and heavy neutrinos masses and mixings suffices to determine their Dirac Yukawa couplings. Expand
Constraining sterile neutrino dark matter with phase space density observations
We apply phase space density considerations to obtain lower bounds on the mass of the sterile neutrino as a dark matter candidate. The bounds are different for non-resonant production, resonantExpand
General CP violation in minimal left–right symmetric model and constraints on the right-handed scale
Abstract In minimal left–right symmetric theories, the requirement of parity invariance allows only one complex phase in the Higgs potential and one in the Yukawa couplings, leading to a two-phaseExpand
Right-handed quark mixings in minimal left-right symmetric model with general CP violation
We solve systematically for the right-handed quark mixings in the minimal left-right symmetric model which generally has both explicit and spontaneous CP violations. The leading-order result has theExpand
