Dear colleague

This letter is the third (and final) announcement of the sixteenth (16th) workshop entitled

"What Comes Beyond the Standard Models?"


which took place at Bled, Slovenia, from 14th of July (arrival day, afternoon) to 21st of July 2013 (departure day, morning).

NEW: The web page containing presentations is available here.

This page contains links to maps of Bled etc.

Web conferences using VIA system are planned during the Workshop, as was the case for the previous four years (you can see the videos, as well the Proceedings, at -- click 'enter the site' on the main page, click the link ' previous', select 'conferences' and then select one of the Bled workshops). We expect several contributions at distance with the use of VIA system.

PLEASE NOTE : To reach the websites of our current and previous workshops, please use the following URL pattern:, where ???? represents the respective year of the workshop. However, the sites are also available at the URLs that have been previously communicated to you by the Organizing Committee.


Our workshop is organized for the purpose of answering the open questions in the standard model of the electroweak and colour interactions, and the cosmological standard model, like:

o What is the most promising first step beyond the standard model, which would explain and possibly justify the assumptions of the standard model:
* families of massless fermions with particular quantum numbers, that is charges in connection with spins,
* massless gauge boson fields
* and a scalar field, which after causing the electroweak break determines together with assumed Yukawa couplings masses of weak bosons and masses and mixing matrices of fermions?

o There are several proposals in the literature, which are trying to explain the assumptions of the standard model. Which one is the most promising? How much have different proposals in common?

o Among the most open questions of the standard model is the origin of families:
* Why there are families at all and how many families shall we be able to observe at the LHC?

o May the existence of more than so far observed families, say four families, help to explain why are masses and the mixing matrix of quarks so different from those of leptons?

o What is the origin of the dark matter? What properties has it?

o Have the so far observed charges a common origin? Have then the corresponding gauge fields a common origin as well?

o What is the origin of the Higgs, the scalar with the fermionic weak charge? How many scalars are there?

o What is the origin of the two energy scales:
* The colour phase transition and
* the electroweak phase transition scale?

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 breaking of symmetries down to the noticeable ones, coming from some higher dimension d? What is d, infinite, any, or one could even start from zero?

o Where do possible Majorana properties of fermions originate?

o What can we learn from the model in which all fermions have come by fermionization from original bosons?

o Can all known elementary particles -- fermions -- be understood as different states of only one particle, with a unique internal space of only two kinds of spin?

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

o How do discrete symmetries change in the evolution of the universe? How are the discrete symmetries defined when space has more than (3+1) dimensions?

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

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


About our workshops

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 these questions in a small group.

In the last fifteen years we have organized fifteen workshops entitled ``What Comes Beyond the Standard Models?" 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 thirteen 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 conference 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.

About location

Bled is a nice town by the lake of the same name, surrounded by mountains, with many comfortable hotels. Home page of Bled, containing information for http://www.bled.siin several languages.

The Physical Society together with the Mathematical Society owns a house, whose owner was our well known mathematician Josip Plemelj. This house can accept 16 people in 8 rooms. The street location of the house is Presernova cesta 39, Bled. It also has a lecture room for around 20 people. There is some place in the Plemelj's house. However, if you want the hotel reservation, then you can do that by yourself (Bled homepage contains links to hotels, we might have some arrangement with hotel Astoria). If you want us to do that then, please, let us know very soon.



We are trying to keep the costs low. The Conference Fee will be 450 EUR for the whole duration of the Workshop at Bled (or 60 EUR per day) and it will cover breakfast, coffee, lunch-snacks and dinner for 7 days, and 30 EUR for the Proceedings (already included in 450 EUR).

In addition, the price of weakly accommodation in Villa Plemelj is 200 EUR (sharing a double bedroom) or 400 EUR (for single occupancy) and it is paid separately from the Conference Fee.

By the way, we are still negotiating for somewhat lower prices.


Letter of invitation

Please let us know, if you need a letter of invitation from the organizing committee either for your institute/university or for a visa application. We shall be glad to send you the letter of invitation after your response to this announcement.


We recommend that you bring appropriate shoes and parkas for trekking and mountaineering.


The workshop is organized by the DMFA (Society of Mathematicians, Physicists and Astronomers of Slovenia). The computer facilities are sponsored by the FMF, University of Ljubljana. The workshop is sponsored by the Slovenian National Committee for Physics, DMFA and Beyond Semiconductor/BS Storitve d.o.o.

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 (although the talks usually, because of many questions and interruptions, last pretty longer). In the rest of the workshop we shall discuss the open problems.
