The third announcement of the twelft workshop organized by
Norma Mankoč Borštnik, Holger Bech Nielsen and Maxim Yu. Khlopov

Dear colleague

This letter is the third announcement of the twelft workshop entitled

"What Comes Beyond the Standard Model?"


This year will (as already the last year) the video workshop take place. The announce topics and the program will be available on the via website

This year we shall have, as the last year, the wireless network connection, available in the Plemelj's house.

It would be much appreciated now that you again confirm your attendance (say, by the end of May). If you need a formal letter of invitation just
let us know an we will send it to you. Any comments/suggestions on topics for discussion and on workshop in general are welcome.


which will take place at Bled from 14th of July (arrival day, afternoon) to 24th of July 2009 (departure day, morning).

Our workshop is organized for the purpose of answering some of the open questions in the electroweak Standard Model like:

o Why has Nature made a choice of four (noticeable) dimensions while all the others, if existing, are hidden? And what are the properties of space-time in the hidden dimensions?

o How could Nature make the decision about the breaking of symmetries down to the noticeable ones, coming from some higher dimension d?

o Why is the metric of space-time Minkowskian and how is the choice of metric connected with the evolution of our universe(s)?

o Why do massless fields exist at all? Where does the weak scale come from?

o Why do only left-handed fermions carry the weak charge? Why does the weak charge break parity?

o What is the origin of Higgs fields? Where does the Higgs mass come from?

o Do Majorana-like particles exist?

o Where do the generations come from? Can higher generations serve as dark matter candidates?

o Can all known elementary particles be understood as different states of only one particle, with a unique internal space of spins and charges?

o How can all gauge fields (including gravity) be unified and quantized?

o What is the composition of our universe and which possible candidates for dark matter are allowed by available data?

o Is it possible to create universe in a laboratory?

o What is the role of symmetries in Nature?

o What is the origin of the field which caused inflation?

o What new can bring the imaginary part of a Lagrangean?

o What is the role of torsion in gravity?

o What is the role of noncommutativity in field theories?

The aim of the workshop is to bring together physicists, who are trying to find the answers to some of these and other open questions from the field of the elementary particles and cosmology and who would enjoy to actively discuss the above questions in a small group.

In the last eleven years we organized nine workshops entitled ``What Comes Beyond the Standard Model?" They took place annually in July since 1998. Each year we spent ten days, trying to answer these questions in a very pleasant and relaxing atmosphere. We have published seven volumes of Proceedings to these workshops (one in 1999, and then one volume every year since 2001). In the year 2003 we have also organized, in addition and with the help of EURESCO, the first conference in a conference series "What comes beyond the Standard models?" titled "Euroconference on symmetries beyond the Standard models" from 12. - 17. of July 2003 in Portoroz, Slovenia. Proceedings volume published in 2003 contains write-ups of the talks at this conference.

The Physical Society together with the Mathematical Society owns a house, whose owner was the well known mathematician Josip Plemelj (access map is available here). This house can accept 16 people in 8 rooms. It also has a lecture room for around 20 people.

Bled is a nice town by the lake of the same name, surrounded by mountains, with many comfortable hotels.

The workshop is organized by the University of Ljubljana, Faculty of Mathematics and Physics, Department of Physics. We have asked the European Physical Society and the Slovenian Ministry of Higher Education, Science and Technology to sponsor this workshop. The workshop is sponsored by the Slovenian National Committee for Physics, DMFA, Department of Physics, FMP, University of Ljubljana.

One page contribution

You may send a one page contribution to the workshop.

Suggestions of discussions

We also ask you to write in a few sentences the suggestions for the open problems, which you are prepared to lead the discussions for, or you suggest the discussions about.


It is planned that in the first two or three days everybody will present her or his work in a one hour talk. In the rest of the workshop we shall discuss the open problems.
