When Energy Goes Missing: New Physics in $b \to s ν ν$ with Sterile Neutrinos

Tobias Felkl, Anjan Giri, Rukmani Mohanta +1

Belle II recently reported the first measurement of $B^{+} \to K^{+} + inv$ , which is $2.8 σ$ above the Standard Model prediction. We explore the available parameter space of new…

Probing general $U (1)^{'}$ models with non-universal lepton charges at FASER/FASER2, COHERENT and long-baseline oscillation experiments

Tobias Felkl, Tong Li, Jiajun Liao +1

The general anomaly-free $U (1)^{'}$ models allow non-universal lepton charges. We explore the sensitivities of FASER/FASER2, COHERENT and DUNE/T2HK precision experiments to the new ga…

Riding the Seesaw: What Higgsstrahlung May Reveal about Massive Neutrinos

Tobias Felkl, Adam Lackner, Michael A. Schmidt

We investigate if the projected high-precision measurements of the cross section of the Higgsstrahlung process $e^{+} e^{-} \to Z h$ at a future electron-positron collider can be utilis…

Flavour anomalies meet flavour symmetry

Innes Bigaran, Tobias Felkl, Claudia Hagedorn +1

We construct an extension of the Standard Model with a scalar leptoquark $ϕ \sim (3, 1, - \frac{1}{3})$ and the discrete flavour symmetry $G_{f} = D_{17} \times Z_{17}$ to explain anomalies ob…

Recoil imaging for directional detection of dark matter, neutrinos, and physics beyond the Standard Model

C. A. J. O'Hare, D. Loomba, K. Altenmüller +164

Recoil imaging entails the detection of spatially resolved ionization tracks generated by particle interactions. This is a highly sought-after capability in many classes of detecto…

A Tale of Invisibility: Constraints on New Physics in $b \to s ν ν$

Tobias Felkl, Sze Lok Li, Michael A. Schmidt

The Belle II experiment will measure the rare decays $B \to K ν ν$ and $B \to K^{*} ν ν$ with increased sensitivity which can hence be expected to serve as a very efficient probe of new p…

The Singly-Charged Scalar Singlet as the Origin of Neutrino Masses

Tobias Felkl, Juan Herrero-Garcia, Michael A. Schmidt

We consider the generation of neutrino masses via a singly-charged scalar singlet. Under general assumptions we identify two distinct structures for the neutrino mass matrix. This…
