Invisible Higgs boson, continuous mass fields and unHiggs mechanism
X. Calmet, N. G. Deshpande, X. G. He +1
We explore the consequences of an electroweak symmetry breaking sector which exhibits approximately scale invariant dynamics -- i.e., nontrivial fixed point behavior, as in unparti…
Measuring the stability of fundamental constants with a network of clocks
G. Barontini, L. Blackburn, V. Boyer +41
The detection of variations of fundamental constants of the Standard Model would provide us with compelling evidence of new physics, and could lift the veil on the nature of dark m…
Absolutely Stable Proton and Lowering the Gauge Unification Scale
S. M. Barr, X. Calmet
A unified model is constructed, based on flipped in which the proton is absolutely stable. The model requires the existence of new leptons with masses of order the weak sca…
Charged Black Hole Remnants at the LHC
G. L. Alberghi, L. Bellagamba, X. Calmet +2
We investigate possible signatures of long-lived (or stable) charged black holes at the Large Hadron Collider. In particular, we find that black hole remnants are characterised by…
Seesaw induced Higgs Mechanism
X. Calmet
We discuss a two scalar doublets model which induces the Higgs mechanism by means of a seesaw mechanism. This model naturally predicts a light Higgs scalar whose mass is suppressed…
QSNET, a network of clocks for measuring the stability of fundamental constants
G. Barontini, V. Boyer, X. Calmet +19
The QSNET consortium is building a UK network of next-generation atomic and molecular clocks that will achieve unprecedented sensitivity in testing variations of the fine structure…
