This letter is the second announcement of the twenty-first workshop entitled

which will take
place at Bled, Slovenia, from** 23rd of June 2018** (arrival day,
afternoon) to **1st of July 2018** (departure day, morning).

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

The program has not been fixed
yet.

This page contains links to maps of Bled etc. and will be updated with later call (in the beginning ofJune).

The following links might be of interest:

__bled2017bsm containing workshop announcements and presentations of most talks, as well as the pdf of the printed workshop Proceedings for 2017. For previous years workshops can be found on analogous URLs by just substituting 2017 with the desired year in the above address for the workshop home page.__

Web conferences using VIA system are planned during the Workshop at Bled, as was the case for the previous seven years (you can see the videos, as well as the Proceedings, at http://viavca.in2p3.fr/site.html - 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 (every participant can suggest a new topic):

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?

* What are masses and charges of the dark matter?

* Are there charge asymmetries in the dark matter?

* Do primordial black holes contribute to 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)?

o Can cosmological measurements observe gravitino contribution to the dark matter?

o Quantum mechanics and singularity of black holes?

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 twenty 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

conference.

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.si 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 www.Bled.si contains links to hotels). 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 530 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 50 EUR
for the Proceedings, (already included in 530 EUR).

In addition, the price of weakly accommodation in Villa Plemelj is 220
EUR (sharing a double bedroom) or 440 EUR (for single occupancy)

and it is paid separately from the Conference Fee.

These costs concern only the part at Bled from 23. June - 1. July 2018, eventual Ljubljana and Bled after parts have to be paid separately.

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

You may send a one page contribution to the workshop.

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.
