We generalize the type II seesaw framework. Requiring absence of fine-tuning and arbitrarily small parameters leads to dynamical lepton number breaking at the electroweak scale and a rich LHC phenomenology, including a smoking gun signature that allows to distinguish our model from the usual type II seesaw scenario.
A certain class of new physics models includes long-lived, electrically charge-neutral particles. A displaced vertex is a spectacular signature to probe such particles productions at the high energy colliders, with almost zero background. In the context the minimal gauged $B-L$ extended Standard Model (SM), we consider a pair creation of Majorana right-handed neutrinos (RHNs) at the high...
The recent detection of coherent elastic neutrino-nucleus elastic scattering (CE$\nu$NS) by the COHERENT experiment has enabled new area of neutrino physics. Apart from neutrino experiments using the stop pion source, the CE$\nu$NS measurement may be complemented by reactor experiments. We studied this complementarity between the accelerator and reactor CE$\nu$NS experiments for constraining...
This talk will comment on the underlying statistics, model evaluation, application and usage of MultiNest for the optimization of coherent scattering neutrino detection experiments. We will discuss an approach which incorporates signal and background uncertainties leading to parameter estimations and distributions for a given likelihood.
We discuss the future possible uses of this approach...
We
present an effective theory for neutrino interactions with quarks, gluons and photons
that includes operators up to dimension 7. We perform a matching of these opera-
tors into nucleon operators in order to describe low energy processes as the recently
observed coherent scattering on nuclei. We compare the contribution of these new
interactions with the results from COHERENT and CHARM...
We discuss novel ways in which neutrino oscillation experiments can probe dark matter. In particular, we focus on interactions between neutrinos and ultralight (“fuzzy”) dark matter particles with masses of order 10^-22 eV. It has been shown previously that such dark matter candidates are phenomenologically successful and might help ameliorate the tension between predicted and observed small...
The standard story is that neutrino mass eigenstates are produced as wavepackets at the same point in spacetime and separate along their journey to the detector, which can cause neutrino oscillations to dampen over long baselines. However, we find that when a calculation is done in quantum field theory, making reference to only measured quantities, that a different picture emerges for how...
Near detectors (ND) at neutrino oscillation experiments will be subjected to unprecedented neutrino fluxes. We explore this to encourage the search for leptophilic new physics in rare neutrino scattering processes like neutrino-electron scattering and neutrino trident production. After addressing some inconsistencies with previous rates for neutrino trident production in the SM, we present...
