Title Dark-sector seeded solution to the strong CP problem Type Journal Article
Year 2023 Publication (down) Physical Review D Abbreviated Journal Phys. Rev. D
Volume 108 Issue 9 Pages 095003 - 6pp
Keywords
Abstract We propose a novel realization of the Nelson-Barr mechanism “seeded” by a dark sector containing scalars and vectorlike quarks. Charge parity (CP) and a Z8 symmetry are spontaneously broken by the complex vacuum expectation value of a singlet scalar, leaving a residual Z2 symmetry that stabilizes dark matter (DM). A complex Cabibbo-Kobayashi-Maskawa matrix arises via one-loop corrections to the quark mass matrix mediated by the dark sector. In contrast with other proposals where nonzero contributions to the strong CP phase arise at the one-loop level, in our case this occurs only at two loops, enhancing naturalness. Our scenario also provides a viable weakly interacting massive particle scalar DM candidate.

Title Revamping Kaluza-Klein dark matter in an orbifold theory of flavor Type Journal Article
Year 2023 Publication (down) Physical Review D Abbreviated Journal Phys. Rev. D
Volume 108 Issue 3 Pages 035046 - 11pp
Keywords
Abstract We suggest a common origin for dark matter, neutrino mass and family symmetry within the orbifold theory proposed in [Phys. Lett. B 801, 135195 (2020); Phys. Rev. D 101, 116012 (2020)]. Flavor physics is described by an A(4) family symmetry that results naturally from compactification. Weakly interacting massive particle dark matter emerges from the first Kaluza-Klein excitation of the same scalar that drives family symmetry breaking and neutrino masses through the inverse seesaw mechanism. In addition to the “golden” quark-lepton mass relation and predictions for 0 nu beta beta decay, the model provides a good global description of all flavor observables.

Title Leptonic neutral-current probes in a short-distance DUNE-like setup Type Journal Article
Year 2024 Publication (down) Physical Review D Abbreviated Journal Phys. Rev. D
Volume 109 Issue 11 Pages 115007 - 12pp
Keywords
Abstract Precision measurements of neutrino -electron scattering may provide a viable way to test the nonminimal form of the charged and neutral current weak interactions within a hypothetical near -detector setup for the Deep Underground Neutrino Experiment (DUNE). Although low -statistics, these processes are clean and provide information complementing the results derived from oscillation studies. They could shed light on the scale of neutrino mass generation in low -scale seesaw schemes.

Title Constraining neutrinoless double beta decay Type Journal Article
Year 2012 Publication (down) Nuclear Physics B Abbreviated Journal Nucl. Phys. B
Volume 861 Issue 3 Pages 259-270
Keywords
Abstract A class of discrete flavor-symmetry-based models predicts constrained neutrino mass matrix schemes that lead to specific neutrino mass sum-rules (MSR). We show how these theories may constrain the absolute scale of neutrino mass, leading in most of the cases to a lower bound on the neutrinoless double beta decay effective amplitude.

Title Neutrino oscillations and the seesaw origin of neutrino mass Type Journal Article
Year 2016 Publication (down) Nuclear Physics B Abbreviated Journal Nucl. Phys. B
Volume 908 Issue Pages 436-455
Keywords
Abstract The historical discovery of neutrino oscillations using solar and atmospheric neutrinos, and subsequent accelerator and reactor studies, has brought neutrino physics to the precision era. We note that CP effects in oscillation phenomena could be difficult to extract in the presence of unitarity violation. As a result upcoming dedicated leptonic CP violation studies should take into account the non-unitarity of the lepton mixing matrix. Restricting non-unitarity will shed light on the seesaw scale, and thereby guide us towards the new physics responsible for neutrino mass generation.
