The gauge coupling constant unification at the low (O(TeV)) scale can be obtained just in four dimensions, without help of the power like renormalization group evolution in extra dimensions, due to the presence of some extra particle states at intermediate scales. We show explicit examples of such extra states in the range of 100 GeV – 1 TeV which can be easily observed on future colliders and ...

1 Introduction This final discussion session was based on feedback from Workshop participants, who were each asked to list three main issues that they felt had been important in the Workshop as a whole. Mary, Janet and Paul clustered these issues for purposes of discussion. Jen took notes (thanks Jen!), and Paul has put them together into the following semi-coherent text. The original notes (wi...

Response to Referee #4 We would like to thank Referee #4 for the review and comments. In general we agree with the presented suggestions and will incorporate these in the final submission. Comment: ===================== The paper provides a basic description of the representation of physical and chemical processes included in the model, although these descriptions should be expanded to include ...

As we tried to point out in our recent article (Anderson, Silverstein, Ritz, & Jones, 1977), the approximations we made there were oversimplifications of the complex reality of the nervous system—made so we could discuss only a few aspects of a very difficult problem. In Anderson et al. (1977), we considered a model that is partially linear. Whatever their theoretical shortcomings, linear syste...

We consider the impact of the kt algorithm on energy flow into gaps between jets in any QCD hard process. While we confirm the observation that the kt clustering procedure considerably reduces the impact of non-global logarithms, we unearth yet new sources of logarithmic enhancement, that stem from using the kt algorithm to define the final state. We comment on the nature of the logarithms we f...
