The Super Charm–Tau factory at the Budker Institute of Nuclear Physics (Novosibirsk, Russia) is an electron-positron collider that will operate in the center-of-mass energy range from 2 to 5-6 GeV with the peak luminosity of about $10^{35}$ cm$^{−2}$s$^{−1}$. The main goal of experiments is to study processes with c quark or τ leptons in the final state. The experiments at Super Charm-tau...

This talk will present a status overview of ongoing LHCb upgrade.
The new detector is designed to operate at the instantaneous luminosity of
2·10^33 cm-2s-1, more than five times higher than in Run 2.
A crucial part of the upgrade is the software-only trigger, which should be
able to select the desired events at 30MHz input rate with up to six
visible interactions per bunch...

From six leptonic atoms (e^+ e^- ), (μ^+ e^- ), (μ^+ μ^- ), (τ^+ e^- ), (τ^+ μ^- ), (τ^+ τ^- ) only positronium (e^+ e^- ) and muonium (μ^+ e^- ) were observed. Observation and study of dimuonium (μ^+ μ^- ) will test QED and quantum mechanics computations in the new regime. Dimuonium radius is 200 times smaller than positronium; therefore, it has a higher new-physics reach potential in...

The overview of two running BINP electron-positron colliders VEPP-4M (1-5 GeV/beam) and VEPP-2000 (0.15-1 GeV/beam) is presented. Since 2016 both colliders are joint to the single accelerator complex via common injector of high quality intensive beams. In 2017 VEPP-2000 resumed data taking after 3 years of upgrade. The luminosity was increased in a factor of 3-5 in a whole energy range.

The BESIII detector and BEPCII accelerator represent major upgrades over the previous version of BES and BEPC; the facility is used for
studies of hadron spectroscopy and ?-charm physics. The design luminosity was reached in 2016, setting a new world record for the accelerator in
this energy regime. After opertaing for more than ten years, BESIII has achieved great success. In my...

Spectroscopy of light and heavy quarks
Invited Oral
The KLOE-2 experiment at the INFN Laboratori Nazionali di Frascati has finished its data-taking campaign at the DAΦNE ϕ-factory with the collection of 5.5 fb$^{-1}$ of integrated luminosity. A peak luminosity of $2.4\times 10^{32} cm^{-2}s^{-1}$ and a maximum daily integrated of 14 pb$^{-1}$ were achieved with the crab waist scheme of beam collisions.
KLOE-2 represents the continuation of...

The super tau-charm facility is of rich in the physics program, is an unique platform for the physics with charmed quark and tau lepton, and provide a great opportunity for study of QCD, exotic hadrons as well as search for new physics. BEPCII/BESIII, which is the only one machine running at the tau-charm region at present, is producing fruitful physics results, but will end its mission in 5-8...

Symmetries (lepton flavor violation, lepton universality)
Invited Oral
High precision measurements of the ground state hyperfine structure (HFS)
of muonium, a leptonic system made of a bound state of a positive muon
with an electron, is a stringent tool for testing bound-state quantum
electrodynamics (QED) theory, determining fundamental constants of the
muon magnetic moment and mass, and searches for new physics. Muonium is
the most suitable system to...

The J-PARC muon $g-2$/EDM experiment (E34 experiment) aims to measure the muon anomalous magnetic moment with a precision of 0.5 ppm and search for muon electric dipole moment with a sensitivity of $10^{-21}~e\cdot$cm. The method of this experiment
is independent of Fermilab's experiment, and a low-emittance muon beam and a factor of 20 smaller muon storage magnet are utilized. A new muon...

The MUonE experiment aims to measure with very high-precision the hadronic contribution to the running of alpha $\Delta\alpha_{had}(t)$, for space-like transferred momenta $t = q^2 < 0$. This measurement has to be performed by means the elastic scattering of high-energetic muons (160 GeV) on electrons target at rest. The precise knowledge of $\Delta\alpha_{had}(t)$ will allow to calculate the...

Lepton Flavour Violation in the charged lepton sector (CLFV) is forbidden in the Standard Model. Therefore, the observation of CLFV process would be clear evidence of physics beyond the Standard Model.
The COMET (COherent Muon to Electron Transitions) experiment will measure one of these processes: $\mu N \rightarrow eN$ at the Japan Proton Accelerator Research Complex (J-PARC) in Tokai,...
