Roadmap and New Strong Forces of Nature<br />
The centre is designed to cover, during its lifetime, strategic areas of research orbiting around<br />
the fundamental problem of the “Origin of Mass” which is the “trait d’union” connecting them:<br />
• Electroweak Symmetry Breaking/Model Building<br />
• Dynamical Origin of Dark Matter and Inflation<br />
• Strong Interactions<br />
In the following we review the research we have been involved in during the reporting period.<br />
We plan to further extend our line or research below for the coming reporting year according to<br />
the original work-plan and milestones.<br />
Two staff members per research area will be the primary investigators according to their expertise.<br />
We expect to involve two postdocs per area of research. There is sufficient flexibility within<br />
this research structure to allow for the young researchers to pick the topic(s) which best suits<br />
their interests. Within each research project introduced below we present the methodological<br />
approach we will employ to achieve our goals.<br />
It is important to mention that shortly after the inaugural collisions, a number of new important<br />
experimental results were published independently by the ATLAS and CMS collaborations setting<br />
important constraints on extensions of the Standard Model. A relevant result is that certain<br />
theoretically constrained versions of the Minimal Supersymmetric Standard Model are showing<br />
tension with the experimental results. Interestingly our recent (of Dynamical Electroweak<br />
Symmetry Breaking type) and novel extensions (via magnetic duals) of the Standard Model are<br />
still top runners for discovery at CERN. We are looking forward to future experimental releases<br />
of data from the CERN experiments!<br />
Quantum Chromo Dynamics (QCD), the theory of “strong interactions”, constitutes one of the<br />
pillars of the Standard Model of particle interactions. It is responsible for the very existence of<br />
ordinary matter while leading to an extremely rich and interesting phenomenology ranging<br />
from the physics of the nucleus to the dynamics and composition of compact astrophysical objects<br />
such as neutron stars.<br />
Several experiments worldwide, existing and planned, such as LHC (CERN Geneva), DAΦNE<br />
(LNF Frascati), FAIR (GSI Darmstadt), TJNAF (Newport News), BES-III/BEPCII (Beijing),<br />
MAMI (Mainz), ELSA (Bonn), Tevatron (Fermilab, USA), BaBar/PEP-II (SLAC USA), Belle/<br />
KEK-B(Tsukuba) and CLEO (Cornell), are designed to investigate its many phenomenological<br />
aspects. QCD is responsible for the dynamical origin of mass of protons and neutrons, constituting<br />
about four percent of the Universe, i.e. the visible part.<br />
Another fundamental property of QCD is that it drives the spontaneous breaking of the electroweak<br />
symmetry, even in the absence of the Higgs boson, with a contribution to the weak<br />
gauge boson masses of the order of thirty MeV. The QCD-driven Higgs mechanism led Weinberg<br />
and Susskind to propose that the Higgs mechanism could emerge from a new strongly interacting<br />
theory, called Technicolor. The techni-hadronic scale should then be approximately<br />
one thousand times bigger than the QCD one, in order to accommodate for the experimental<br />
value of the weak gauge bosons masses.<br />
