The Belle II experiment at the SuperKEKB energy-asymmetric e+e− collider is a substantial upgrade of the B factory facility at the Japanese KEK laboratory. The target luminosity of the machine is 6×1035 cm−2s−1 and the Belle II experiment aims to record 50 ab−1 of data, a factor of 50 more than its predecessor. With this data set, Belle II will be able to measure the Cabibbo-Kobayashi-Maskawa...

BESIII has collected data sets of 448.2 M $\psi(3686)$ events and 10 B $J/\psi$ events. The huge clean data samples provide an excellent opportunity to search for new physics. We report the search for decay $J/\psi\to \gamma + \rm invisible$, which is predicted by next-to-minimal supersymmetric model. Without significant signal found, we gave around 6.2 times better UL than previous CLEO-c’s...

Search for high mass BSM are performed in dilepton final states using the proton-proton collision dataset at a center-of-mass energy of 13 TeV collected by CMS in 2016, 2017, and 2018, corresponding to integrated luminosities up to ~140/fb. The observations are consistent with the expectations of the standard model in all searched channels. Upper limits on the cross sections are calculated and...

Many theories beyond the Standard Model predict new phenomena, such as Z’, W’ bosons, or heavy leptons, in final states with isolated, high-pt leptons (e/mu/tau). Searches for new physics with such signatures, produced either resonantly or non-resonantly, are performed using the ATLAS experiment at the LHC. This includes a novel search that exploits the lepton-charge asymmetry in events with...

Leptoquarks (LQ) are predicted by many new physics theories to describe the similarities between the lepton and quark sectors of the Standard Model and offer an attractive potential explanation for the lepton flavour anomalies observed at LHCb and flavour factories. The ATLAS experiment has a broad program of direct searches for leptoquarks, coupling to the first-, second- or third-generation...

Many extensions to the Standard Model predict new phenomena occurring at high mass. These include new scalar or vector resonances, as well as new heavy fermions. This talk will summarize recent searches for such heavy particles based on 13 TeV pp collision data collected by the CMS experiment at the LHC.

Several theories beyond the Standard Model predict the existence of additional neutral or charged Higgs particles other than the 125 GeV Higgs boson. In this presentation, the latest CMS results on searches for these particles will be discussed.

With the full Run 2 pp collision dataset collected at 13 TeV, very detailed measurements of Higgs boson properties and its interactions can be performed using its decays into bosons and fermions. These measurements are combined allowing to reach the highest possible measurement precision. This talk presents the latest measurements of the Higgs boson properties by the ATLAS experiment in...

The width and the structure of its couplings to the known SM particles is very important to determine whether 125GeV Higgs is the SM Higgs boson. The off-shell technique provides unique way to measure the Higgs boson width and probe the small anomalous couplings which are allowed in SM. In this talk, a recent measurement on the Higgs width and anomalous couplings with the ZZ decay channel is presented.

The latest results on the production of Higgs boson pairs (HH) in the ATLAS experiment are reported, with emphasis on searches based on the full LHC Run 2 dataset at 13 TeV. In the case of non-resonant HH searches, results are interpreted both in terms of sensitivity to the Standard Model and as limits on the Higgs boson self-coupling. Search results on new resonances decaying into pairs of...

The NOvA experiment is aimed to solve the fundamental neutrino problems: precise determination of neutrino oscillation parameters, determination of neutrino mass hierarchy, search for the CP-violation in the leptonic sector. NOvA consists of the near detector on the Fermi National Laboratory site, where the muon neutrinos are produced in the NuMI accelerator complex, and the far detector...

Latest results from the CUORE experiment
The Cryogenic Underground Observatory for Rare Events (CUORE) is the first bolometric experiment searching for 0νββ decay that has been able to reach the one-tonne mass scale. The detector, located at the LNGS in Italy, consists of an array of 988 TeO2 crystals arranged in a compact cylindrical structure of 19 towers. CUORE began its first physics...

The IceCube Neutrino Observatory is the world largest neutrino telescope, instrumenting one cubic kilometre of Antarctic ice. IceCube started its operation in 2011 and a diffuse flux of neutrino was discovered in 2013. To this day the sources of those neutrinos are still largely unknown. One of the most promising neutrino source candidates are blazars, Active Galactic Nuclei with jets aligned...

KM3NeT is a deep-sea infrastructure mainly devoted to the detection of neutrinos over a large range of energy. It hosts two Cherenkov neutrino telescopes in different sites of the Mediterranean Sea: ARCA, located at 3500 m sea depth, offshore Sicily, will look for high energy neutrinos coming from astrophysical sources; ORCA, installed 2500 m under the sea level, in front of the Provencal...

The IceCube Upgrade involves development of several new optical modules:dual-PMT (D-Eggs), multi-PMT (mDOMs), and upgraded traditional modules (pDOMs). In particular, the D-Eggs offer a high-efficiency and cost-effective solution compared to original IceCube modules. Results extracted from the IceCube Upgrade will compliment low energy analyses, as well as be a key component of the upcoming...

The Pacific Ocean Neutrino Experiment (P-ONE) initiative strives to push the boundaries of high-energy astronomy by creating a next-generation, large-scale neutrino telescope. In this process, P-ONE benefits highly from an already existing deep-sea infrastructure, the NEPTUNE observatory, established and in operation by Ocean Networks Canada (ONC). NEPTUNE provides power and data connections...

High-energy astrophysical neutrinos, discovered by IceCube, are now regularly observed. The observation rate remains small due to their low flux, such that open questions about high-energy neutrino astrophysics and particle physics remain limited by statistics at best, or unanswered at worst. Fortunately, this situation will improve in the next years: new neutrino telescopes will come online,...

We explore the new physics scenarios case by case that can
modify the interactions between neutrinos and matter at future tau neutrino telescopes. Recent progress of multimessenger astronomy, especially the ultra-high-energy neutrino observations at IceCube, has sparked a campaign towards neutrino detection at extreme energies around
the Greisen-Zatsepin-Kuzmin cutoff around 10^9 GeV. A...
