[iTIMP: isotriplet Technicolor Interacting Massive Particle as Dark Matter. Mads T. Frandsen, (Oxford U., Theor. Phys.) , Francesco Sannino, (Southern Denmark U., CP3-Origins) . CP3-ORIGINS:2009-19, Nov 2009. 4pp. e-Print: arXiv:0911.1570 [hep-ph], Submitted for Publication] Superweakly interacting dark matter We studied a superweakly interacting dark matter particle motivated by minimal walking technicolor theories. Our WIMP is a mixture of a sterile state and a state with the charges of a standard model fourth family neutrino. We showed that the model can give the right amount of dark matter over a range of the WIMP mass and mixing angle. We computed bounds on the model parameters from the current accelerator data including the oblique corrections to the precision electroweak parameters, as well as from cryogenic experiments, Super-Kamiokande and from the IceCube experiment. We showed that consistent dark matter solutions exist which satisfy all current constraints. However, almost the entire parameter range of the model lies within the combined reach of the next generation experiments. [Superweakly interacting dark matter from the Minimal Walking Technicolor. Kimmo Kainulainen, Kimmo Tuominen, Jussi Virkajarvi, . CP3-ORIGINS-2009-26, Dec 2009. 29pp. Published in JCAP 1002:029,2010. e-Print: arXiv:0912.2295 [astro-ph.CO]] Gravitational Waves We investigated the production and possible detection of gravitational waves stemming from the electroweak phase transition in the early universe in models of minimal walking technicolor. In particular we discussed the two possible scenarios in which one has only one electroweak phase transition and the case in which the technicolor dynamics allows for multiple phase transitions.

CP3-ORIGINS-2009-24, Nov 2009. 29pp. e-Print: arXiv:0911.4096 [hep-ph], Physical Review D, in press.] In the near future we plan to: • Construct new benchmarks for models of dynamical electroweak symmetry breaking passing precision measurements. • Implement the respective low-energy effective theories in computer programmes able to provide the relevant physical processes for LHC searches. • Investigate the cosmological consequences of dynamical electroweak symmetry breaking from dark matter to baryogenesis. • Study various extensions featuring dynamical electroweak symmetry breaking and their consequences for flavour physics. • Compare dynamical electroweak symmetry breaking with physical results from LHC when available.

This part of the workplan has multiple purposes: it will lead to a deeper understanding of the Origin of Mass, both theoretically and phenomenologically; it allows us to get closer to cosmology by direct investigation of models of Dark Matter and baryogenesis; it will lead to a better understanding of the LHC complex phenomenology and its possible outcomes. In the long run, and depending on the LHC outcome, we will also explore how these models may fit in a more unified theory of all forces, including gravity. One can envision, for example, the possibility of marrying supersymmetry and technicolor at a scale higher than the electroweak. Flavour Physics The goal of this project is to help uncovering an underlying and more fundamental flavour structure of the SM. This will help guiding our intuition for constructing more solid extensions of the SM. Perturbed S3 neutrinos We studied the effects of the perturbation which violates the permutation symmetry of three Majorana neutrinos but preserves the well known (23) interchange symmetry. This is done in the presence of an arbitrary Majorana phase which serves to insure the degeneracy of the three neutrinos at the unperturbed level. [Perturbed S(3) neutrinos. Renata Jora, (Barcelona, Autonoma U.) , Joseph Schechter, M. Naeem Shahid, (Southern Denmark U., CP3-Origins & Syracuse U.). CP3-ORIGINS-2009-12, SU-4252-898, Phys.Rev.D80:093007,2009.] Discrete Minimal Flavour Violation We investigated the consequences of replacing the global flavour symmetry of Minimal Flavour Violation (MFV) SU(3)_QxSU(3)_UxSU(3)_Dx..., by a discrete D_QxD_UxD_Dx.. symmetry. Goldstone bosons resulting from the breaking of the flavour symmetry generically lead to bounds on new flavour structure many orders of magnitude above the TeV-scale. The absence of Goldstone bosons for discrete symmetries constituted the primary motivation of our work. Less symmetry implies further invariants and renders the mass flavour basis transformation observable in principle and calls for a hierarchy in the Yukawa matrix expansion. We showed, through the dimension of the representations, that the (discrete) symmetry in principle does allow for additional Delta F = 2 operators. [On discrete Minimal Flavour Violation. Roman Zwicky, Thomas Fischbacher, (Southampton U.) Published in Phys.Rev.D80:076009,2009.] In the future we plan to further investigate the flavour structure stemming out from technicolor type extensions of the SM. Matter-Antimatter Asymmetry The matter-antimatter asymmetry, namely the violation of the discrete CP symmetry, is a phenomenon intimately linked to the origin of fermion masses. A better characterisation and understanding of CP violation would help in our quest to go beyond the SM. CP is violated by weak interactions. The SM does not explain this violation, but successfully accounts for it under the form of a phase in the quark mixing matrix. CP³-Black book 14
