Exothermic Dark Matter at LZ
Carlos Henrique de Lima
We investigate whether the high-energy nuclear recoil reported by the LUX-ZEPLIN (LZ) experiment can be explained by exothermic dark matter. We realize this framework in a minimal…
On the Origins of Varying Gauge Couplings
Carlos Henrique de Lima, David McKeen, David E. Morrissey +1
Variations in the gauge couplings of the Standard Model have been searched for experimentally and proposed as solutions to open questions in fundamental physics. Varying gauge coup…
Neutrino Electroweak Couplings and the Neutrino Fog at Belle II
Carlos Henrique de Lima, David McKeen, Afif Omar +1
The mono-photon process at Belle II probes both invisible new states and the electroweak couplings of neutrinos. In this work, we study the proces…
Hadronic Probes of Non-Standard Neutrino Interactions
Carlos Henrique de Lima, David McKeen, John Ng +1
In this work, we study leptonic decays of hadrons as probes of light neutrinophilic scalars that mediate enhanced neutrino self-interactions. Such scalars can be emitted in process…
Novel Phases of a Baryon-Dense QCD-like Theory
Yang Bai, Carlos Henrique de Lima, Daniel Stolarski
We investigate the phases of a strongly coupled QCD-like theory at finite baryon chemical potential using s-confining supersymmetric QCD deformed by anomaly-mediated supersymmetry…
Probing Lepton Number Violation at Same-Sign Lepton Colliders
Carlos Henrique de Lima, David McKeen, John N. Ng +2
Same-sign lepton colliders offer a promising environment to probe lepton number violation. We study processes that change lepton number by two units in the context of Majorana heav…
The Sign of Gauge-Higgs Couplings at Future Lepton Colliders
Carlos Henrique de Lima, Douglas Tuckler
This work investigates the capability of future lepton colliders to determine the sign of the gauge-Higgs coupling through the vector boson fusion (VBF) process. This channel…
Influence of new states in searches for negative gauge-Higgs couplings
Carlos Henrique de Lima, Daniel Stolarski
In this work, we explore how constraints based on interference effects for the negative gauge-Higgs coupling scenario are affected by new physics. Models that achieve this wrong-si…
Can CP be conserved in the two-Higgs-doublet model?
Carlos Henrique de Lima, Heather E. Logan
We study the conditions under which the CP violation in the quark mixing matrix can leak into the scalar potential of the real two-Higgs-doublet model (2HDM) via divergent radiativ…
Electrobaryonic axion: hair of neutron stars
Yang Bai, Carlos Henrique de Lima
Axion-like particles are predicted in many physics scenarios beyond the Standard Model (SM). Their interactions with SM particles may arise from the triangle anomaly of the associa…
Exploring the vacuum structure of gravitationally induced neutrino masses
Carlos Henrique de Lima, Daniel Stolarski
In this work, we explore the proposed mechanism in which the gravitational anomaly generates neutrino masses. We highlight that the leading renormalizable interactions of the n…
Unavoidable Higgs coupling deviations in the -symmetric Georgi-Machacek model
Carlos Henrique de Lima, Heather E. Logan
The -symmetric version of the Georgi-Machacek model does not possess a decoupling limit in which all the new particles can be made arbitrarily heavy, opening the possibility…
Status of negative coupling modifiers for extended Higgs sectors
Carlos Henrique de Lima, Daniel Stolarski, Yongcheng Wu
In this work, we study the status of negative coupling modifiers in extended Higgs sectors, focusing on the ratio of coupling modifiers that probes custodial symmetry violation $λ_…
Probing Dark Sector CP Violation with Electric Dipole Moments and Colliders
Carlos Henrique de Lima, Ben Keeshan, Heather E. Logan +1
We study the experimental constraints on dark sector CP violation that enters the visible sector through a Higgs portal coupling $H^{\dagger} H Z^{\prime}_{μν} \widetilde Z^{\prime…
