The next Jerzy Pniewski and Leopold Infeld Colloquium of the Faculty of Physics will be held on (this) Monday, APRIL THE 26TH, at 4.30 PM.

 This time we will listen to two lectures on the hot topic in the last days, which is the g-2 problem for the muon. It is an interdisciplinary topic, important not only for physicist working in the domain elementary particles.

 The lectures will be:

 FIRST RESULTS FROM THE MUON G-2 EXPERIMENT IN FERMILAB delivered by DR. BRENDAN KIBURG (FNAL, USA)

 and

 THEORETICAL PREDICTIONS AND INTERPRETATIONS OF THE FERMILAB G-2 RESULT delivered by PROF. DOMINIK STOECKINGER (TECHNICAL UNIVERSITY DRESDEN, GERMANY).

 The abstracts of the lectures are provided below this message.

 Here is a link to the Colloquium on the Zoom platform: https://us02web.zoom.us/j/93881687598?pwd=UmFhVUdVSXhnQ2tIVVozNmowSUNtZz09

Meeting ID: 938 8168 7598

Passcode: prv316

 You are welcome to join the meeting 15-30 minutes before the Colloquium to talk or chat in an informal atmosphere.

DR BRENDAN KIBURG (FERMILAB): FIRST RESULTS FROM THE MUON G-2 EXPERIMENT AT FERMILAB

The Muon g-2 Experiment recently reported a new measurement of the anomalous magnetic moment of the muon with a precision of 0.46 parts-per-million. This result is in good agreement with the previous experimental measurement from Brookhaven National Laboratory and has increased the tension with the Standard Model calculation to 4.2 standard deviations, strengthening hints of New Physics. This talk will give a brief description of the experimental history and will provide an overview of the measurement challenges and analysis techniques.

PROF. DOMINIK STOECKINGER (TU DRESDEN): THEORY PREDICTIONS AND INTERPRETATIONS OF THE FERMILAB
G-2 RESULT.

The quantity g-2 of the muon is sensitive to all known elementary particles and all forces between them. In the Standard Model of particle physics a highly precise prediction is possible. The observed deviation from the Standard Model might be due to additional, so far unknown particles or forces. The talk will briefly explain the status of the Standard Model prediction and give an overview of potential implications for physics beyond the Standard Model.
