DOI: 10.1007/jhep02(2022)036
Abstract: Abstract Axion-like particles (ALPs) interacting with the Standard Model can be abundantly produced in proton beam fixed-target experiments. Looking for their displaced decays is therefore an effective search strategy for ALPs with a mass in… read more here.

DOI: 10.1007/jhep07(2020)050
Abstract: Studies of axion-like particles (ALPs) commonly focus on a single type of interaction, for example couplings only to photons. Most ALP models however predict correlations between different couplings, which change the phenomenology in important ways.… read more here.

DOI: 10.1007/s10773-018-3727-1
Abstract: In this work, we study the effects of the vector unparticle on e+e−→ γa processes. From the numerical results, we show that the cross-section with unparticle effects should be about 1014 − 1023 times larger than… read more here.

DOI: 10.1088/1475-7516/2009/12/004
Abstract: Very-high energy photons emitted by distant cosmic sources are absorbed on the extragalactic background light (EBL) during their propagation. This effect can be characterized in terms of a photon transfer function at Earth. The presence… read more here.

DOI: 10.1088/1475-7516/2020/03/046
Abstract: Machine learning (ML) techniques have been applied with tremendous success in many areas of physics. In this work, we use ML to place bounds on the coupling between photons and axion-like particles (ALPs). This coupling… read more here.

DOI: 10.1088/1475-7516/2021/05/004
Abstract: We derive structure formation limits on dark matter (DM) composed of keV-scale axion-like particles (ALPs), produced via freeze-in through the interactions with photons and Standard Model (SM) fermions. We employ Lyman-alpha (Ly-α) forest data sets… read more here.
