Abstract The Large Hadron Collider (LHC) has confirmed the Higgs mechanism to generate
mass in the Standard Model (SM), making it attractive also to consider spontaneous …

The discovery of the Higgs boson has opened a new avenue for exploring physics beyond
the Standard Model. In this review, we discuss cosmological aspects of the simplest Higgs …

A bstract Traditional direct searches for dark matter, looking for nuclear recoils in deep
underground detectors, are challenged by an almost complete loss of sensitivity for light …

We propose a new search for light scalar singlets in rare meson decays. For couplings well
below the electroweak interaction strength, the scalar is long-lived at detector scales and …

Scenarios with new physics particles feebly interacting with the Standard Model sector
provide compelling candidates for dark matter searches. Geared with a set of new …

A bstract 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 …

We investigate the physics case for a dedicated trigger on a low mass, hadronic displaced
vertex at the high luminosity LHC, relying on the CMS phase II track trigger. We estimate the …

The idea that new physics could take the form of feebly interacting particles (FIPs)—particles
with a mass below the electroweak scale, but which may have evaded detection due to their …

A bstract The proposed DarkQuest beam dump experiment, a modest upgrade to the
existing SeaQuest/SpinQuest experiment, has great potential for uncovering new physics …

Axionlike particles (ALPs) emerge in many extensions of the Standard Model as pseudo-
Goldstone bosons of a spontaneously broken global symmetry. Understanding their …
