Probing light axion-like particles in vector boson fusion at CMS with data parking and scouting
Sena Durgut, Mariel Peczak, Gonzalo Alonso-Álvarez +4
Axion-like particles (ALPs) with masses between 10 MeV and 10 GeV and moderately small couplings sit in an experimental blind spot. They decay too fast for intensity-frontier exper…
Tracking axion-like particles at the LHC
Gonzalo Alonso-Álvarez, Joerg Jaeckel, Diego D. Lopes
Highly boosted axion-like particles decaying into photon pairs are notoriously hard to detect at the LHC. The collimated decay photons cannot be individually reconstructed using on…
Leading Logs in QCD Axion Effective Field Theory
Gonzalo Alonso-Álvarez, Fatih Ertas, Joerg Jaeckel +2
The axion is much lighter than all other degrees of freedom introduced by the Peccei-Quinn mechanism to solve the strong CP problem. It is therefore natural to use an effective fie…
Hidden Photon Dark Matter in the Light of XENON1T and Stellar Cooling
Gonzalo Alonso-Álvarez, Fatih Ertas, Joerg Jaeckel +2
The low-energy electronic recoil spectrum in XENON1T provides an intriguing hint for potential new physics. At the same time, observations of horizontal branch stars favor the exis…
On the Wondrous Stability of ALP Dark Matter
Gonzalo Alonso-Álvarez, Rick S. Gupta, Joerg Jaeckel +1
The very low mass and small coupling of axion-like particles (ALPs) is usually taken as a guarantor of their cosmological longevity, making them excellent dark matter candidates. T…
Very Light Asymmetric Dark Matter
Gonzalo Alonso-Álvarez, Julia Gehrlein, Joerg Jaeckel +1
Very light dark matter is usually taken to consist of uncharged bosons such as axion-like particles or dark photons. Here, we consider the prospect of very light, possibly even sub…
Lightish but clumpy: scalar dark matter from inflationary fluctuations
Gonzalo Alonso-Álvarez, Joerg Jaeckel
It has recently been shown [1] that light vector particles produced from inflationary fluctuations can give rise to the dark matter in the Universe. A similar mechanism has been di…
Exploring ALPs beyond the canonical
Gonzalo Alonso-Álvarez, Joerg Jaeckel
Axion-like particles (ALPs) are interesting dark matter candidates both from the theoretical as well as from the experimental perspective. Usually they are motivated as pseudo-Namb…
