Dear colleague

This is the Post-festum of the twenty-ninth Bled workshop entitled "What Comes Beyond the Standard Models?" which took place at Bled, Slovenia, from 6^th of July 2026 (Monday) to 15^th of July 2026 (Wednesday), "virtual" (ZOOM) workshop.

About the Workshop

The "virtual" part was hosted by Cosmovia, http://viavca.in2p3.fr/site.html, courtesy of Prof. Maxim Yu. Khlopov.

We also put your presentations on the workshop homepage (see Workshop Diary). As every year, we plan to publish printed Proceedings with the write-ups of your talks in December 2026. Our Proceedings has now a DOI number -- the 2025 is DOI.51746/9789612977351.

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.

To appear the whole proceedings on arxiv, we shall the arxiv number of your talk, the whole proceedings will appear in Scopus and as a-book.

Aims and Topics

Below is a piece of detailed information on the aims and topics of this year's workshop:

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 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 assumptions of the standard model like:

* the origin of massless family members with their related spins and charges,

* the origin of families of fermions,

* the origin of massless vector gauge fields,

* the origin of the Higgs' scalar and Yukawa couplings for massive quarks and leptons,

* the origin of differences in masses of family members?

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 are 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 the masses of new families?

* What are the properties of new gauge fields?

* What are the properties of new scalar fields?

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

o What is the origin of the energy scales:

* the colour phase transition scale,

* the electroweak phase transition scale,

* the scale at 10¹⁹ 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 they offer?

o What can the complex action bring into the understanding of the properties of our universe?

o Why has Nature chosen four (noticeable) space-time dimensions while all the others (if existing) are hidden?

* What is the starting symmetry and starting space-time dimension of our universe?

o How can all gauge fields, including gravity and scalar fields, be unified and quantised?

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 quantisation 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.

Workshop Background

The workshop aims to bring together physicists from the field of the elementary particles and cosmology, who are trying to find the answers to the above and other open questions and who would enjoy actively discussing these questions in a small group.

In the last twenty-eight years, the workshops entitled "What comes beyond the standard models?" have taken place annually in July since 1998 except 2018, which was in June, and each year we spent about ten days, trying to answer the above (and other) questions in a very pleasant and relaxing atmosphere. We have published twenty-eight volumes of Proceedings from these workshops (one in 1999, and then one volume every year since 2001). In the year 2003, we have also organised, in addition and with the help of EURESCO, the conference titled "Euroconference on symmetries beyond the Standard models" from 12th to 17th of July 2003 in Portoroz, Slovenia. The proceedings volume published in 2003 contains write-ups of the talks at this conference.

Location

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.

Bled

Bled is a nice town by the lake of the same name, surrounded by mountains, with many comfortable hotels. The home page of Bled, containing information for visitors, is available at http://www.bled.si in several languages.

Sponsors

The workshop is organised 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, the 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.
