# Participation in NuFact 2022, Snowbird, USA

From July 30 through 6th August Janusz Gluza took part in NuFact 2022, chairing one of the plenary sessions and giving the talk “PMNS and the number of additional neutrino flavors” https://indico.fnal.gov/event/53004/contributions/243136/attachments/158351/207755/NuFact_2022.pdf. This conference was held in Snowbird, Utah, USA, and focused on neutrino physics and colliders. The twenty-third of the series of yearly international workshops started in 1999.

# We are organizing: Standard Model and Beyond conference, 21-23.10.2022

On October 21-23, 2022, the Symposium of the Fundamental Interactions Physics Section (SFOF) of the Polish Physical Society was held in Katowice. The symposium was organized in a hybrid form; 79 physicists participated in the event (6 online). During the symposium, in addition to the talks, a poster session was held, and the three best posters were selected. A group of participants spent Friday evening in the “Hipnoza” club, while on Saturday evening we got to know the Silesian Planetarium, which was renewed this year, Chorzów Park.

Janusz Gluza described what happened 10 years ago in the Large Hadron Collider – the first detection of the Higgs boson by ATLAS and CMS experiments – in a short popular article available in Polish on our institute webpage and in English https://us.edu.pl/wydzial/wnst/en/2022/07/01/10-rocznica-wykrycia-bozonu-higgsa/

# Our Visits at CERN in 2022 and Precision Physics Workshop

Biswajit Karmakar, Krzysztof Grzanka, Janusz Gluza, Bartosz Dziewit and Ievgen Dubovyk visited CERN from 29.05 to 18.06 as a part of the UŚ-CERN FCC scientific cooperation. In parallel we took part in the two-week *Precision calculations for future e+e- colliders: targets and tools* workshop, where Janusz Gluza gave a talk on *Feynman parametrization and numerical integration*.

# Modern methods of calculating Feynman integrals and related general multidimensional integrals – lectures.

We invite all students of the Faculty of Science and Technology of the University of Silesia to participate in lectures devoted to modern methods of calculating Feynman integrals and related general multidimensional integrals.

These lectures will be conducted by a recognized specialist in this field:

Dr. Gabor Somogyi.

They are organized within the framework of the POWER project.

**About Us**

The research is carried out in several directions, with an emphasis on precise calculations of higher-order perturbation effects for electroweak observables at LHC and future lepton accelerators. We are particularly focused on the activities related to the FCC-ee project at CERN.

**The research topics of the group include:**

1. Precise calculation of parameters and observables of the Standard Model (SM)

2. Phenomenology of SM extensions (neutrinos, additional gauge bosons, Higgs scalars)

3. Development of methods and tools for the calculation of multi-loop Feynman integrals

**Detailed research goals:**

1. Use of new computational techniques and advanced algebra to define and constraint elements of the neutrino mixing matrix with non-standard neutrinos.

2. Phenomenology of non-standard particles at the LHC and future lepton accelerators (H++, W2, Z2, heavy neutrinos).

Precise calculation of electroweak of electroweak pseudoobservables for the LHC and future accelerators.

3. Developing analytical and numerical methods of calculating multi-loop integrals.

4. Analysis of masses and mixing matrices in models with the so-called family symmetry.

5. Analysis of finite groups up to the order of 1025 assuming the existence of family symmetries for 3HDM models.
