Models that produce axionlike particles (ALPs) after cosmological inflation due to
spontaneous U (1) symmetry breaking also produce cosmic-string networks. Those axionic …

A bstract The Electron-Ion Collider (EIC), a forthcoming powerful high-luminosity facility,
represents an exciting opportunity to explore new physics. In this article, we study the …

Axion-like particles (ALPs) that decay into photon pairs pose a challenge for experiments
that rely on the construction of a decay vertex in order to search for long-lived particles. This …

We interpret the recent excess in a rare decay of the Higgs boson, H→ Z γ, using a light
axionlike particle (ALP) in the mass range 0.05–0.1 GeV. The dominant decay of such a light …

We study axion-like particles (ALPs) with quark-flavor-violating couplings at the LHC.
Specifically, we focus on the theoretical scenario with ALP-top-up and ALP-top-charm …

This thesis investigates gravity at different energy scales to understand the fundamental
properties and constituents of the observable dark universe. The thesis contains two main …
