we are looking forward to seeing you soon at Bled. It is not so hot as in most other places, so that we shall have an opportunity for nice discussions and pleasant walks.

This letter is the third (and final) announcement of the eighteenth (18th) workshop entitled

**which will take place at** **Bled, Slovenia (Plemelj's Villa, Prešernova cesta 39), from 11th of July (arrival day, afternoon) to 19th of July 2015 (departure day, morning). **

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).

Web conferences using VIA system are planned during the Workshop, as was the case for the previous five years (you can see the videos, as well the Proceedings, at www.cosmovia.org -- 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 and possibly justifying the assumptions of the standard model about:

* the origin of massless family members with their 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 dark matter,

* the origin of dark energy,

* the origin of ordinary matter-antimatter asymmetry

* the origin of differences in masses of family members

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 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?

* How many of the open questions of the standard model does a particular proposal answer?

o How many families shall we be able to observe at the LHC?

o How many scalar fields shall the LHC observe?

o What properties has the dark matter?

* Is the charge asymmetry in the dark matter?

* Can the charge asymmetry be related to the baryon asymmetry?

o What is the origin of the two energy scales:

* the colour phase transition scale 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?

* 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 do string theories really mean?

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 seventeen 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.

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 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 www.Bled.si 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 510 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 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 11-19 July 2015, Ljubljana
and Bled after has 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 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.
