Dear colleague,

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

"What Comes Beyond the Standard Models?"

which will take place at Bled, Slovenia, from 4th of July 2020 (Saturday, arrival day, afternoon) to 12th of July 2020 (Sunday, 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. Usually we make the program together with the participants and according to the number of continuations each talk needs. (There are usually, namely, many questions interrupting each talk.)

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:

  • the links to workshop pages for previous years can be found at  http://bsm.fmf.uni-lj.si/
  • home page of the previous 2019 workshop can be found at  http://bsm.fmf.uni-lj.si/bled2019bsm containing workshop announcements and presentations of most talks, as well as the pdf of the printed workshop Proceedings for 2019. For previous years workshops can be found on analogous URLs by just substituting 2019 with the desired year in the above address for the workshop home page.
  • home page of Cosmovia, http://viavca.in2p3.fr/site.html, 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 go to the link for Previous - Conferences).

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.htm - 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.

 

Program

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 of fermions - quarks and leptons,
* the origin of massless vector gauge fields,
* the origin of the Higgs's scalar and Yukawa couplings for quarks and leptons,
* the origin of differences in masses of family members?


o And going beyond, while explaining:

* the origin of dark matter and its properties (when comparing cosmological observation, direct detections and all the proposed models),
* the masses and charges of the dark matter,
* the contribution of primordial black holes to the dark matter,
* the origin of the dark energy,
* the origin of ordinary matter-antimatter asymmetry.


o How to interpret the so far made searches for new physics?


* 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 Origin of the lepton number nonconservation:


* What can different models and experiments say about the lepton number nonconservation?


o What is the origin of the two energy scales:


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


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 How can one understand the discrete symmetries in Kaluza-Klein like theories?
o How can all gauge fields (including gravity and scalar fields) 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 Quantum mechanics and the black hole singularity?
o The role of black holes in the history of the universe.
o Could the fermions have the integer spin and yet be second quantized fields, obeying the Pauli principle?
o Can one observe the phenomena of high energy physics at solid or fluid at low temperature?
o Many other open problems.

 

 

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 twenty two years we have organized workshops entitled “What Comes Beyond the Standard Models?" They took place annually in July since 1998, except 2018, which was in June. Each year we spent about ten days, trying to answer these questions in a very pleasant and relaxing atmosphere. We have published twenty 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 Portorož,Slovenia. Proceedings volume published in 2003 contains write-ups of the talks at this conference.


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 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.

 

Cost

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). The tourist tax is not included.

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 4. July - 12. July 2020, 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 shall be glad to send you the letter of invitation after your response to this announcement.

Excursion:

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

Sponsors

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.

Presentations


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.
