Since the discovery of a scalar particle compatible with the Standard Model (SM) Higgs
boson at the Large Hadron Collider (LHC) in 2012, no convincing signals of physics beyond …

We study a scenario in which the dilaton, a pseudo-Goldstone boson of the spontaneous
breaking of conformal symmetry, provides a portal between dark matter and the visible …

A bstract We study a model in which dark matter couples to the Standard Model through a
dilaton of a sector with spontaneously broken approximate scale invariance. Scale …

A bstract In this paper, we explore the possibility that a light dilaton can be the first sign of
new physics at the LHC. The dilaton could emerge in approximate scale invariant UV …

Models where dark matter is a part of an electroweak multiplet feature charged particles with
macroscopic lifetimes due to the charged-neutral mass split of the order of pion mass. At the …

We present an extension of the simplified fast detector simulator of MadAnalysis 5–the SFS
framework–with methods making it suitable for the treatment of long-lived particles of any …

A bstract It has been pointed out recently that the presence of dilaton field in the early
Universe can dilute the neutralino dark matter (DM) abundance, if Universe is not radiation …

We consider a dark matter model where the relic density is set by conversion-driven feeze-
out. This mechanism predicts long-lived particles at the LHC requiring small couplings and a …

We study a model with a Higgs-like dilaton and a standard model gauge-singlet scalar dark
matter candidate. We begin by updating the status of identifying the observed 125 GeV …

Long-lived particles have significant enough lifetimes as to, when produced in collisions,
leave a distinct signature in the detectors. Driven by increasingly higher energies, trigger …
