Dear colleague

best regards to all of you. We shall soon meet at Bled.
This letter is the third (and last) announcement of the twentieth workshop (20th - anniversary) entitled


"What Comes Beyond the Standard Models?"


which will take place at Bled, Slovenia, from 09th of July 2017 (arrival day, afternoon) to 17th of July 2017 (departure day, morning).

There is a real possibility for the participants to come earlier in Ljubljana, and stay few days longer at Bled.

If you have not already sent the arival and departure dates, please do this as soon as you can.

We will celebrate this anniversary workshop also with a popular talk for the general audience at Bled (Holger Bech Nielsen will give a talk titled 'How far do we understand our Universe?').


We would also appreciate that (some) of the talks at our workshop would be review talks on your (our) topics, manifesting the achievements in these 20 years. We would also appreciate that you let as know also your suggestions for discussion topics to those, listed below.

This page contains links to maps of Bled etc. and will be updated with later calls (there will be two more calls, one in May and one in June).

The following links might be of interest:

  • the links to workshop pages for previous years can be found at
  • home page of the previous 2016 workshop can be found at containing workshop announcements and presentations of most talks, as well as the pdf of the printed workshop Proceedings for 2016. For previous years workshops can be found on analogous URLs by just substituting 2016 with the desired year in the above address for the workshop home page.
  • home page of Cosmovia,, which hosts video conferences at our (and many other) conferences for the last several years, courtesy of Prof. Maxim Yu. Khlopov (on the Cosmovia home page click 'enter', then go to the link for older conferences).

Web conferences using VIA system are planned during the Workshop at Bled, as was the case for the previous six years (you can see the videos, as well as 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.



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, explaining the assumptions of the standard model like:

* the origin of massless family members with their related spin and charges,
* the origin of families,
* the origin of massless vector gauge fields,
* the origin of the Higgs's scalar and Yukawa couplings,
* the origin of differences in masses of family members?

o And going beyond, while explaining:

* the origin of dark matter,
* the origin of dark energy,
* the origin of ordinary matter-antimatter asymmetry.

o How to interpret the so far made searches for new physics on the LHC and other new experiments and how to predict new observations?

* How many families shall we be able to observe at the LHC and at which energies?
* How many scalar fields shall the LHC observe?
* What are masses of new families?
* What are properties of new scalar fields?

o What properties has the dark matter?

* Is the charge asymmetry in the dark matter?

o What is the origin of the two energy scales:

* the colour phase transition scale and
* the electroweak phase transition scale?

o There are several proposals in the literature, which are trying to explain the assumptions of the standard model.

* How much have different proposals in common?

o What can strings and membranes contribute to our understanding of elementary particle physics and cosmology?

* What do string theories really mean?

o What does the complex action bring into the understanding of the properties of our universe?
o What can we learn from the model in which all fermions have come by fermionization from original bosons?
o Why has Nature made a choice of four (noticeable) dimensions while all the others (if existing) are hidden?

* How does the compactification occur?
* What are properties of space-time in the hidden dimensions?

o Where do possible Majorana properties of fermions originate?
o How can one understand the discrete symmetries in Kaluza-Klein like theories?
o How can all gauge fields (including gravity) be unified and quantized?
o What is the origin of the field which caused inflation?
o What can new measurements of gravitational waves contribute to understanding the cosmology (and elementary fields)?


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 nineteen years we have organized workshops entitled “What Comes Beyond the Standard Models?" They took place annually in
July since 1998. Each year we spent about ten days, trying to answer these questions in a very pleasant and relaxing atmosphere. We have
published seventeen 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

About the 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 in 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 at most 18 people in 9 rooms. The street location of the house is Presernova cesta 39, Bled. It also has a lecture room for around 20 people. We also can make the hotel reservation, or you can do that by yourself (Bled homepage contains links to hotels). If you want us to do that then, please, do it very soon as the hotels will not have many free rooms by early June.



We are trying to keep the costs low. The Conference Fee will be 510 EUR for the whole duration of the Workshop (or 60 EUR per day) and it will
cover breakfast, coffees, lunch-snacks and dinner for 8 days, and 30 EUR for the Proceedings, (already included in 510 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.

These costs concern only the part at Bled from 09-17 July 2017, eventual Ljubljana and Bled after parts have to be paid separately.


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 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 workshop is sponsored by DMFA and the Department of Physics, FMF, University of Ljubljana with the computer equipment.

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 much longer). In the rest of the workshop we shall discuss the open problems.
