Nuclear beta and electron capture (EC) decay serve as sensitive probes of the structure and symmetries at the microscopic scale of our Universe. As such, precision measurements of the final-state products in these processes can be used as powerful laboratories to search for new physics from the meV to TeV scale, as well as addressing fundamental questions of quantum mechanics at the subatomic...
In the framework of the Standard Model Effective Field Theory (SMEFT), the Standard Model can be seen as a low-energy approximation of a deeper, more fundamental theory that introduces new heavy particles at a higher energy scale,

The Higgs boson was discovered in 2012 using data from the Large Hadron Collider (LHC) at CERN. Since its discovery, it has been observed interacting with heavy standard model (SM) particles such as Z and W bosons and heavy quarks. A more interesting search focuses on the Higgs interactions with light SM particles such as the muon manifested in the Higgs-to-dimuon decay path. According to SM...
The ATLAS experiment, located at CERN, studies high energy proton-proton and heavy-ion collisions produced by the Large Hadron Collider (LHC), the world's largest particle accelerator. One of the main goals of the ATLAS experiment is to study the properties of the Higgs boson. With the discovery of the Higgs boson at ATLAS and CMS in 2012, the focus has shifted to studying the properties of...
KDK and KDK+ research is focused on the Potassium-40 decays (40K). The most frequent decay mode is a β- decay to calcium-40. 40K also has an electron capture decay to the excited state of argon-40, as well as two much rarer decays, in the form of an electron capture and a β+ decay to the ground state of argon-40. The electron capture decay of 40K to the ground state of 40Ar was only recently...
Calculation of the free muon lifetime is a classical particle physics problem that was solved long time ago and its solution can be found in various textbook. Evaluation of the bound muon decay rate is significantly more complicated problem that requires a lot of laborious calculations and contains some non trivial physical effects as well. First calculation of the bound muon lifetime was done...
