Particle Physics: Experiment and Phenomenology
The measurements of spectroscopy and decays of hadron states, in particular those formed of heavy quarks, can provide valuable experimental input for QCD. The LHCb detector at the LHC is dedicated to heavy flavour physics. High luminosity of LHC, high b/c-hadron production cross-section and unique capabilities of LHCb detector in reconstructing heavy hadron decays has unprecedented...
The talk is devoted to three latest results.
First is a search for the axion like particles in the decay
$K^+ \to \pi^+ \pi^0 a$:
A high statistics data sample of the K+ decays is recorded by the OKA collaboration. A missing mass analysis
is performed to search for a light invisible pseudoscalar axion-like particle (ALP) in the decay $K^+ \to \pi^+ \pi^0 a$. No signal is observed, the...
Thermal dark matter models with particle masses below the electroweak scale can provide an explanation for the observed relic dark matter density. This would imply the existence of a new feeble interaction between the dark and ordinary matter. The main purpose of the NA64 experiment is a search for sub-GeV dark matter production using the method of missing energy signature. The searches are...
