Dear colleague

This is the follow-up page of the twenty-sixth workshop entitled

"What Comes Beyond the Standard Models?"


which took place at Bled, Slovenia, from 10th of July 2023 (Monday, arrival day, afternoon) to 19th of July 2023 (Wednesday, departure day, morning), real and "virtual"  (ZOOM)  workshop.

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

Our workshop was 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 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 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 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 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 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 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.


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-five 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-four 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 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 contains links to hotels). If you want us to do that then, please, let us know very soon.
