Dark matter as the source of neutrino mass: theory overview and experimental prospects
Ivania M. Ávila, Anirban Karan, Sanjoy Mandal +2
We review theoretical frameworks in which small neutrino masses arise radiatively through interactions with a dark sector that also accounts for cosmological dark matter (DM). A pr…
Reinterpretation of searches for long-lived particles from meson decays
Rebeca Beltrán, Giovanna Cottin, Martin Hirsch +2
Many models beyond the Standard Model predict light and feebly interacting particles that are often long-lived. These long-lived particles (LLPs) in many cases can be produced from…
Long-lived heavy neutral leptons from mesons in effective field theory
Rebeca Beltrán, Giovanna Cottin, Juan Carlos Helo +3
In the framework of the low-energy effective field theory of the Standard Model extended with heavy neutral leptons (HNLs), we calculate the production rates of HNLs from meson dec…
Long-lived heavy neutral leptons with a displaced shower signature at CMS
Giovanna Cottin, Juan Carlos Helo, Martin Hirsch +3
We study the LHC discovery potential in the search for heavy neutral leptons (HNL) with a new signature: a displaced shower in the CMS muon detector, giving rise to a large cluster…
Searching for light neutralinos with a displaced vertex at the LHC
Giovanna Cottin, Juan Carlos Helo, Fabián Hernández-Pinto +2
We study a bino-like light neutralino () produced at the LHC from the decay of a scalar lepton () through the process $pp\to \tilde e_{L} \to e\tilde χ_1^…
Long-lived heavy neutral leptons at the LHC: four-fermion single- operators
Rebeca Beltrán, Giovanna Cottin, Juan Carlos Helo +3
Interest in searches for heavy neutral leptons (HNLs) at the LHC has increased considerably in the past few years. In the minimal scenario, HNLs are produced and decay via their mi…
