Opening the 100-Year Window for Time-Domain Astronomy

Opening the Window for Technicolor

Recently a new class of technicolor models are proposed, using technifermions of symmetric second-rank tensor. In the models, one can make reasonable estimates of physical quantities like the Higgs mass and the size of oblique corrections, using a correspondence to super Yang-Mills theory in the Corrigan-Ramond limit. The models predict a surprisingly light Higgs of mass, mH = 150 ∼ 500GeV and ...

Opening the Window for Electroweak Baryogenesis

We perform an analysis of the behaviour of the electroweak phase transition in the Minimal Supersymmetric Standard Model, in the presence of light stops. We show that, in previously unexplored regions of parameter space, the order parameter v(T c)/T c can become significantly larger than one, for values of the Higgs and supersymmetric particle masses consistent with the present experimental bou...

Data challenges of time domain astronomy Matthew

Astronomy has been at the forefront of the development of the techniques and methodologies of data intensive science for over a decade with large sky surveys and distributed efforts such as the Virtual Observatory. However, it faces a new data deluge with the next generation of synoptic sky surveys which are opening up the time domain for discovery and exploration. This brings both new scientif...

Experimental approaches for 100 TeV astronomy

The high energy end of γ-ray source spectra might provide important clues regarding the nature of the processes involved in γ-ray emission. Several galactic sources with hard emission spectra extending up to more than 30 TeV have already been reported. Measurements around 100 TeV and above should be an important goal for the next generation of high energy γ-ray astronomy experiments. Here we pr...
