Gravitational Wave Scattering on Magnetic Fields
Valerie Domcke, Camilo Garcia-Cely, Sung Mook Lee
The conversion of gravitational to electromagnetic waves in the presence of background magnetic fields is known as the inverse Gertsenshtein effect, analogous to the Primakoff effe…
Challenges and Opportunities of Gravitational Wave Searches above 10 kHz
Nancy Aggarwal, Odylio D. Aguiar, Diego Blas +34
The first direct measurement of gravitational waves by the LIGO and Virgo collaborations has opened up new avenues to explore our Universe. This white paper outlines the challenges…
Symmetries and Selection Rules: Optimising Axion Haloscopes for Gravitational Wave Searches
Valerie Domcke, Camilo Garcia-Cely, Sung Mook Lee +1
In the presence of electromagnetic fields, both axions and gravitational waves (GWs) induce oscillating magnetic fields: a potentially detectable fingerprint of their presence. We…
Belle II sensitivity to long-lived dark photons
Torben Ferber, Camilo Garcia-Cely, Kai Schmidt-Hoberg
In this letter we point out that the Belle II experiment has a unique sensitivity to visibly decaying long-lived dark photons. Concentrating on the signatures with a single high en…
A novel search for high-frequency gravitational waves with low-mass axion haloscopes
Valerie Domcke, Camilo Garcia-Cely, Nicholas L. Rodd
Gravitational waves (GWs) generate oscillating electromagnetic effects in the vicinity of external electric and magnetic fields. We discuss this phenomenon with a particular focus…
Physics reach of a long-lived particle detector at Belle II
Sascha Dreyer, Torben Ferber, Anastasiia Filimonova +9
We have studied three realistic benchmark geometries for a new far detector GAZELLE to search for long-lived particles at the \superkekb accelerator in Tsukuba, Japan. The new dete…
Long-lived Dark Higgs and Inelastic Dark Matter at Belle II
Michael Duerr, Torben Ferber, Camilo Garcia-Cely +2
Inelastic dark matter is an interesting scenario for light thermal dark matter which is fully consistent with all cosmological probes as well as direct and indirect dark matter det…
Potential of radio telescopes as high-frequency gravitational wave detectors
Valerie Domcke, Camilo Garcia-Cely
In the presence of magnetic fields, gravitational waves are converted into photons and vice versa. We demonstrate that this conversion leads to a distortion of the cosmic microwave…
A Practical and Consistent Parametrization of Dark Matter Self-Interactions
Xiaoyong Chu, Camilo Garcia-Cely, Hitoshi Murayama
Self-interacting dark matter has been proposed to explain the apparent mass deficit in astrophysical small-scale halos, while observations from galaxy clusters suggest that the cor…
Finite-size dark matter and its effect on small-scale structure
Xiaoyong Chu, Camilo Garcia-Cely, Hitoshi Murayama
If dark matter has a finite size that is larger than its Compton wavelength, the corresponding self-interaction cross section decreases with the velocity. We investigate the implic…
Velocity Dependence from Resonant Self-Interacting Dark Matter
Xiaoyong Chu, Camilo Garcia-Cely, Hitoshi Murayama
The dark matter density distribution in small-scale astrophysical objects may indicate that dark matter is self-interacting, while observations from clusters of galaxies suggest th…
Strong gravitational radiation from a simple dark matter model
Iason Baldes, Camilo Garcia-Cely
A rather minimal possibility is that dark matter consists of the gauge bosons of a spontaneously broken symmetry. Here we explore the possibility of detecting the gravitational wav…
Core formation from self-heating dark matter
Xiaoyong Chu, Camilo Garcia-Cely
Cosmological simulations of the CDM model suggest that the dark matter halos of dwarf galaxies are denser in their center than what observational data of such galaxies imply. In…
Self-interacting Spin-2 Dark Matter
Xiaoyong Chu, Camilo Garcia-Cely
Recent developments in bigravity allow one to construct consistent theories of interacting spin-2 particles that are free of ghosts. In this framework, we propose an elementary spi…
Self-interacting dark matter as a solution to the problems in small-scale structures
Camilo Garcia-Cely, Xiaoyong Chu
Dark matter self-interactions are a well-motivated solution to the core-vs.-cusp and the too-big-to-fail problems. They are commonly induced by means of a light mediator, that is a…
Neutrino Lines from Majoron Dark Matter
Camilo Garcia-Cely, Julian Heeck
Models with spontaneously broken global lepton number can lead to a pseudo-Goldstone boson as a long-lived dark matter candidate. Here we revisit the case of singlet majoron dark m…
Can the relic density of self-interacting dark matter be due to annihilations into Standard Model particles?
Xiaoyong Chu, Camilo Garcia-Cely, Thomas Hambye
Motivated by the hypothesis that dark matter self-interactions provide a solution to the small-scale structure formation problems, we investigate the possibilities that the relic d…
Phenomenology of left-right symmetric dark matter
Camilo Garcia-Cely, Julian Heeck
We present a detailed study of dark matter phenomenology in low-scale left-right symmetric models. Stability of new fermion or scalar multiplets is ensured by an accidental matter…
Probing the Inert Doublet Dark Matter Model with Cherenkov Telescopes
Camilo Garcia-Cely, Michael Gustafsson, Alejandro Ibarra
We present a detailed study of the annihilation signals of the inert dark matter doublet model in its high mass regime. Concretely, we study the prospects to observe gamma-ray sign…
Production Regimes for Self-Interacting Dark Matter
Nicolas Bernal, Xiaoyong Chu, Camilo Garcia-Cely +2
In the context of Self-Interacting Dark Matter as a solution for the small-scale structure problems, we consider the possibility that Dark Matter could have been produced without b…
WIMP and SIMP Dark Matter from the Spontaneous Breaking of a Global Group
Nicolas Bernal, Camilo Garcia-Cely, Rogerio Rosenfeld
We propose and study a scalar extension of the Standard Model which respects a symmetry remnant of the spontaneous breaking of a global symmetry. Co…
Cosmological and astrophysical signatures of dark matter annihilations into pseudo-Goldstone bosons
Camilo Garcia-Cely, Alejandro Ibarra, Emiliano Molinaro
We investigate a model where the dark matter particle is a chiral fermion field charged under a global symmetry which is assumed to be spontaneously broken, leading to a pse…
Dark matter production from Goldstone boson interactions and implications for direct searches and dark radiation
Camilo Garcia-Cely, Alejandro Ibarra, Emiliano Molinaro
The stability of the dark matter particle could be attributed to the remnant symmetry that arises from the spontaneous breaking of a global U(1) symmetry. This plausible scen…

Neil D. Christensen, P. de Aquino, N. Deutschmann +7
Support for interactions of spin-3/2 particles is implemented in the FeynRules and ALOHA packages and tested with the MadGraph 5 and CalcHEP event generators in the context of thre…
