We review topics in searches for axion-like-particles (ALPs), covering material that is
complementary to other recent reviews. The first half of our review covers ALPs in the …

A bstract The Effective Field Theory (EFT) Lagrangian for a generic axion-like particle (ALP)
has many free parameters, and leaves quite some freedom for the expected …

Recently, the MiniBooNE experiment at Fermilab has updated the results with increased
data and reported an excess of 560.6±119.6 electronlike events (4.7 σ) in the neutrino …

We explore single and double flavor-violating scalar (flavon) production at the 13 and 14
TeV LHC in an effective field theory formulation where flavons always change the flavor of …

Axion‐like particles (ALPs) and heavy neutral leptons (HNLs) are both well‐motivated
extensions of the Standard Model. As ALPs couple to on‐shell fermions proportionally to …

We investigate the prospects for detecting axionlike particles (dubbed as “a”) via the decay
Z→ aff¯ at future Z factories. Considering the decay channels a→ μ+ μ-and a→ bb¯, four …

The exclusive production of axionlike particles (ALPs) by gluon–induced interactions is
investigated in this exploratory study considering pp and P b P b collisions for the energies …

We study exotic Higgs decays h→ ZX, with X an invisible beyond the Standard Model (SM)
particle, resulting in a semidark final state. Such exotic Higgs decays may occur in theories …

Axion like particles (ALPs) and right-handed neutrinos (RHNs) are two well-motivated dark
matter (DM) candidates. However, these two particles have a completely different origin …

Heavy neutral leptons (HNLs) are often among the hypothetical ingredients behind nonzero
neutrino masses. If sufficiently light, they can be produced and detected in fixed-target-like …
