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

"What Comes Beyond the Standard Models?"which will after two ''virtual'' years and also two "partly virtual and partly real years" take place at Bled, Slovenia, from** 8 ^{th}
of July 2024** (Monday, arrival day,
afternoon) to

The ''virtual'' part will be hosted by Cosmovia, courtesy of Prof. Maxim Yu. Khlopov.

Please let us know if you are interested and can participate during that period. We will then send you further information.

For the ''virtual'' part of the workshop we will need besides the title also the abstracts of your talks and you will have to send your talk (as a pdf or PowerPoint file) to Maxim and Norma probably at least a day in advance.

To make a schedule we will therefore need a title of your talk (and preferably also an abstract). We will try to make a preliminary schedule a few days before the workshop starts and update and modify it daily as necessary for talk continuations and discussions.

We will also put your presentations on this homepage. As every year, we plan to publish printed Proceedings with the write-ups of your talks in December 2024. Our Proceedings have now a DOI number --
DOI.10.51746/9789612972097 for 2023.

You will receive detailed instructions on this at the end of the virtual workshop and also later. We also expect informational support from MDPI journals Symmetry, Universe, Particles ad Physics and selected invited contributions will be published for free, if accepted, in the corresponding special issues.

After appearing on arxiv, we shall need for that the arxiv number of
your talk, the whole proceedings will appear in Scopus.

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

Our workshop is organized for the purpose of answering the open questions in the elementary particle physics and cosmology, like (every participant can suggest a new topic):

o Can Dirac's second quantization postulates for fermion and boson fields be explained

* with a finite number of Clifford odd and even "basis vectors" describing the internal space of fermions and bosons and with the continuous infinite basis in ordinary momentum or coordinate space?

o Can the need for the Fadeev-Popov ghosts in Feynman's diagrams be explained by the Clifford odd and even "basis vectors" in odd-dimensional spaces?

o Are the Kaluza-Klein-like theories, with gravity as the only interaction among fermions in higher dimensional spaces, the right next step to understand* all the observed properties of quarks and leptons and antiquarks and antileptons, and

* of their vector and scalar gauge vector fields?

o What is the most promising step beyond the standard model 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 origin of the dark energy,

* the origin of ordinary matter-antimatter asymmetry.

o What is the dynamics of the dark matter in our solar system?

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 can different models and experiments say about the lepton number non conservation?

o What is the origin of the energy scales:* the colour phase transition scale,

* the electroweak phase transition scale,

* the scale at 10^{19}GeV or higher?

o What can strings and membranes contribute to our understanding of elementary particle physics and cosmology,* what understanding of the low energy fermions and the vector and scalar gauge fields do they offer?

o What can the complex action bring into the understanding of the properties of our universe?o Why has Nature made a choice of four (noticeable) dimensions while all the others (if existing) are hidden?

* How does the "compactification" of extra dimensions (if existing) occur?

* What is the starting symmetry and starting dimension of our universe and how can one understand that we do not see the dimensions larger then (3+1)?

* What are properties of space-time in the hidden dimensions?

* Can it be that dynamics in higher dimensions is just frozen out while internal spaces give properties to fields in d=(3+2)?

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 cosmology (and elementary fields)?

o How can the second quantization of the black hole be related to classical singularity?

o How do black holes influence the history of the universe?

o Many other open problems.

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-six 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-six 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.

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 480 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.

In addition, the price of weakly accommodation in Villa Plemelj is 240
EUR (sharing a double bedroom) or 480 EUR (for single occupancy)
and it is paid separately from the Conference Fee.

These costs concern only the part at Bled from 8. July - 17. July 2024.
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 Department of Physics, FMF, University of Ljubljana with the computer equipment and supported by Beyond Semiconductor, and the last several years by MDPI. Also Niels Bohr institute is supporting the workshops, and all those who are paying the living expenses by themselves, if the institutions do not pay their travel and living expenses as well.

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.
