The implications of the Dark-LMA solution to the solar neutrino problem for neutrino-less double beta decay will be discussed. It will be shown that while the predictions for the effective mass governing neutrino-less double beta decay remains unchanged for the inverted mass scheme, that for normal ordering becomes higher for the Dark-LMA parameter space and hits into the ``desert region'' bet ...

In this talk, we introduce a new mechanism of direct baryogenesis by baryon number violating effective operator which is analogous to neutron-antineutron oscillation after electroweak symmetry breaking. Sufficient amount of the baryon asymmetry can be produced through the flavor oscillation after inflaton/moduli decay by the operator during the energy loss processes. We also suggest the mechanism ... More

Neutrinoless double beta decay can significantly help to shed light on the issue of non-zero neutrino mass, as observation of this lepton number violating process would imply neutrinos are Majorana particles. However, the underlying interaction does not have to be as simple as the standard neutrino mass mechanism. The entire variety of neutrinoless double beta decay mechanisms can be approached ef ...

Heavy neutrinos appear in many models of neutrino masses and mixing. In this talk, I will present a new search strategy at hadron colliders based on dynamical jet vetoes. This increases the sensitivity of the trilepton + missing transverse energy search by an order of magnitude and allows future colliders to search for heavy neutrinos with a mass of 10 TeV and above.

We investigate the performance of T2HK in the presence of a light eV scale sterile neutrino. We study in detail its influence in resolving fundamental issues like mass hierarchy, CP-violation (CPV) induced by the standard CP-phase delta13 and new CP-phase delta14, and the octant ambiguity of theta23. We show for the first time in detail that due to the impressive energy reconstruction capabilities ... More

The mirror dark matter model accommodates dark matter in a hidden sector which is isomorphic to the Standard Model, containing mirror partners of Standard Model particles. A weak kinetic mixing interaction allowed by the symmetry between the two sectors gives interactions between charged ordinary and mirror particles. The LUX dark matter direct detection experiment would be sensitive to electron r ... More

We explore the possibility that dark matter interactions with Standard Model particles are dominated by interactions with neutrinos. We examine whether it is possible to construct such a scenario in a gauge-invariant manner. We first study the coupling of dark matter to the full lepton doublet and confirm that this generally leads to the dark matter phenomenology being dominated by interactions wi ... More

A non-relativistic theory effective field theory (NREFT) offers a bottom-up framework to classify Dark Matter (DM) - nucleon interactions relevant for scattering at direct detection experiments by organising the interactions in powers of the momentum transfer $ \vec{q} $. This approach generates a number of operators including P-odd and T-odd operators, which require that the relativistic theory g ... More

We discuss lepton number violating processes in the context of long-baseline neutrino oscillations. We summarise and compare neutrino flavour oscillations in quantum mechanics and quantum field theory, both for standard oscillations and those that violate lepton number. When the active neutrinos are Majorana in nature, the required helicity-reversal gives a strong suppression by the neutrino mass ... More

The study of various lepton number violating (LNV) and lepton flavour violating (LFV) processes is one of the most important gateways to probe and understand the Dirac vs Majorana nature of neutrinos and various mass models of neutrino mass generation. Neutrinoless double beta decay is one of the most important modes beyond the SM to probe the Majorana nature of neutrinos. I will discuss how the e ... More

Since the early 1980s, Feynman and others discussed how quantum systems could be efficiently simulated through tools of quantum computation. Such quantum simulations may in fact turn out to be the only way certain phenomena experimentally difficult to realise can be studied, one such phenomena being neutrino oscillations. Though neutrinos are predicted by the standard model to be massless and ... More

T2K is a long baseline neutrino experiment producing a beam of muon neutrinos at the Japan Particle Accelerator Research Centre on the East coast of Japan and measuring their oscillated state 295 km away at the Super Kamiokande detector. Since 2016 T2K has doubled its data in both neutrino and antineutrino beam modes. Coupled with improvements in analysis techniques this has enabled the experiment ... More

In the development of atomic clocks, some atomic transition frequencies are measured with remarkable precision. These measured spectra may include effects of a new force mediated by a weakly interacting boson. Such effects might be distilled out from possible violation of a linear relation in isotope shifts between two transitions, as known as King's linearity, with relatively suppressed theoretic ... More

As the lepton number and lepton flavor are conserved quantities in Standard Model, observation of charged lepton flavor violation (cLFV) process will provide clues on beyond-Standard model theories. COMET is an experiment at J-PARC, Japan, which will search for neutrinoless conversion of muons into electrons in the field of a nucleus (μ− + N → e− + N); a lepton flavor violating process. The ...

The origin of the neutrino mass is still an open problem in physics and many efforts are being made to solve it. Among the possible solutions, the simplest ones involve an extension of the Standard Model, where new singlet fermions are added. Symmetry-protected variants of the seesaw mechanism, like the Inverse Seesaw, could explain the existence of light-neutrino masses while also providing obse ... More

The MEG experiment took data at the Paul Scherrer Institute in the years 2009-2013 and published the most stringent limit on the charged lepton flavor violating decay mu->egamma: BR(mu->egamma) <4.2 x 10^(-13) @90% C.L. The MEG detector has been upgraded in order to reach a sensitivity of 5 x 10^(-14), which corresponds to an improvement of one order of magnitude. The basic idea of MEG-II is to ... More

Recently the MiniBooNE Collaboration has reported an anomalous excess in muon to electron (anti-)neutrino oscillation data. Combined with long-standing results from the LSND experiment this amounts to a 6.1 sigma evidence for new physics beyond the Standard Model. In this talk I discuss a framework with 3 active and 3 sterile neutrinos with altered dispersion relations that can explain these anoma ... More

The Pierre Auger Observatory is the largest detector for cosmic rays with energies above EeV. The Observatory has established a clear suppression of the fluxes of the highest energy particles, charged nuclei, which are expected to come from extragalactic sources. The contribution of photons and neutrinos from more exotic sources is strongly limited. Cosmic rays are detected through the extensiv ... More
