Universe in a Box: LHC, Cosmology and Lattice Field Theory
Maria Paola Lombardo (Frascati)
Francesco Sannino (Odense)
The main goal of the meeting was to identify the most promising among several emerging avenues of research in the broad field of numerical simulations of field theory. Numerical simulations of field theories are now in a very mature stage. Not only it is possible to explore many aspects of the standard model of particle physics. Also applications beyond the standard model are becoming feasible. In pursuing these not yet standard applications is particularly important to work in close connection with phenomenologists and experimentalists. And, at the same time, to discuss with computer scientists the computational needs and opportunities.
The meeting had 39 registered participants, most of them present for the entire period. The attendance was very well balanced between phenomenologists and lattice theorists. Concerning the specific field of applications, most represented were Technicolor-like theories. We had a broad geographic distribution, with a significant local attendance.
The initial plan of the organisers was to have a restricted number of talks including some reviews. When the number of talks grew above 30, due to a positive response which went beyond our expectations, the organisers decided to accommodate all the talks, asking some of the speakers to include a short pedagogical introduction. This still left room for two main reviews on computational physics, and on dark matter.
We opted for a very short question and answer session at the end of each talk, and for longer discussion sessions (one or two each day) in the conference room. This worked very well with animated discussions, and proposal for new studies.
The original invitation was broad range, and extended to colleagues working in many subjects ranging from quantum gravity to supersymmetry, either numerically or analytically. The number and the quality of the contributions and the content of the discussions clearly selected Technicolor and Technicolor-like models as the most promising avenue of research.
We can certainly conclude that our primary goal - to identify most relevant developments - has been reached.
In addition to this, other outcomes are Initiated discussions on a new European network. Planned medium term visits among the participants, and/or attendance to similar meetings Exchange of raw data between different group, leading to comparative analysis on similar data sets. While this might or might not lead to joint publications, will certainly greatly help resolving a few controversial aspects.
Facilitated the request of computer time in the fields covered by the meeting.
We can conclude that we have reached our main goal, together with other interesting developments.
