Cosmological Abundance of Colored Relics

Christian Gross, Andrea Mitridate, Michele Redi +2

The relic cosmological abundance of stable or long-lived neutral colored particles gets reduced by about a few orders of magnitude by annihilations that occur after QCD confinement…

flavour symmetries as Peccei-Quinn symmetries

Fredrik Björkeroth, Luca Di Luzio, Federico Mescia +1

We investigate to what extent a generic, generation-dependent symmetry acting on the quark Yukawa operators can reduce the number of free parameters by forcing some entries…

Gluequark Dark Matter

Roberto Contino, Andrea Mitridate, Alessandro Podo +1

We introduce the gluequark Dark Matter candidate, an accidentally stable bound state made of adjoint fermions and gluons from a new confining gauge force. Such scenario displays an…

On the nature of the Higgs boson

Damiano Anselmi

Several particles are not observed directly, but only through their decay products. We consider the possibility that they might be fakeons, i.e. fake particles, which mediate inter…

Probing new electroweak states via precision measurements at the LHC and future colliders

Luca Di Luzio, Ramona Gröber, Giuliano Panico

Several new physics scenarios, motivated e.g. by dark matter, feature new electroweakly charged states where the lightest particle in the multiplet is stable and neutral. In such c…

Detecting a Boosted Diboson Resonance

Kaustubh Agashe, Jack H. Collins, Peizhi Du +3

New light scalar particles in the mass range of hundreds of GeV, decaying into a pair of bosons can appear in several extensions of the SM. The focus of collider studies for…

Fusing Vectors into Scalars at High Energy Lepton Colliders

Dario Buttazzo, Diego Redigolo, Filippo Sala +1

We study vector boson fusion production of new scalar singlets at high energy lepton colliders. We find that CLIC has the potential to test single production cross-sections of a fe…

Low- and high-energy phenomenology of a doubly charged scalar

Andreas Crivellin, Margherita Ghezzi, Luca Panizzi +2

We explore the phenomenology of an -singlet doubly charged scalar at the high and low energy frontier. Such a particle is predicted in different new physics models, like lef…

The LHC potential of Vector-like quark doublets

Giacomo Cacciapaglia, Aldo Deandrea, Naveen Gaur +3

The existence of new vector-like quarks is often predicted by models of new physics beyond the Standard Model, and the development of discovery strategies at colliders is the objec…

Study of the theta dependence of the vacuum energy density in chiral effective Lagrangian models at zero temperature

Francesco Luciano, Enrico Meggiolaro

We perform a systematic study of the modifications to the QCD vacuum energy density in the zero-temperature case () caused by a small, but non-zero, value of the par…

Single production of vector-like quarks with large width at the Large Hadron Collider

Alexandra Carvalho, Stefano Moretti, Dermot O'Brien +2

Vector-Like Quarks (VLQs) are predicted by several theoretical scenarios of new physics and, having colour quantum numbers, can copiously be produced at the Large Hadron Collider (…

Super-cool Dark Matter

Thomas Hambye, Alessandro Strumia, Daniele Teresi

In dimension-less theories of dynamical generation of the weak scale, the Universe can undergo a period of low-scale inflation during which all particles are massless and super-coo…

Bounds on Dark Matter decay from 21 cm line

Andrea Mitridate, Alessandro Podo

The observation of the cosmic 21-cm spectrum can serve as a probe for Dark Matter properties. We point out that the knowledge of the signal amplitude at a given redshift allows one…

Dark Matter in the Standard Model?

Christian Gross, Antonello Polosa, Alessandro Strumia +2

We critically reexamine two possible Dark Matter candidate within the Standard Model. First, we consider the exa-quark. Its QCD binding energy could be large enough to mak…
