The evidence for the existence of dark matter, so far is based on its gravitational effects. Nevertheless, many theoretical models assume other non-gravitational very-weak interactions between dark matter and ordinary matter, and to test this hypothesis, different experiments are trying to directly detect dark matter signals at particle accelerators.

The forward BFKL equation is discretized in order to understand momenta difussion into the infrared and ultraviolet by means of a semi-infinite matrix. This matrix is square truncated so an exponentiation is possible, leading to asymptotic eigenstates related to the gluon Green's function at large matrix size. There is also a relation between this truncation and the XXX Heisenberg spin=-1/2...

The present work is mainly focussed on the estimation of the level scheme of $ K=0$ and $K=5$ bands in ${^{240}Am}$ using TQPRM model. While exploring the actinide region we have noticed that the experimental level scheme is not systematic to study the properties of ${^{240}Am}$ nucleus. We have also made the comparison between the theoretical energies and experimental energies which lead...

We present new results of the DANSS experiment on the searches for sterile neutrinos. They are based on approximately 4 million of inverse beta decay events collected at 10.9, 11.9 and 12.9 meters from the reactor core of the 3.1 GW Kalinin Nuclear Power Plant in Russia. The neutrino spectrum dependence on the fuel composition is also presented. We have also measured the reactor power using...

SND@LHC is a compact and stand-alone experiment to perform measurements with neutrinos produced at the LHC in a hitherto unexplored pseudo-rapidity region of 7.2 < $\eta$ < 8.6, complementary to all the other experiments at the LHC. The experiment is to be located 480 m downstream of IP1 in the unused TI18 tunnel. The detector is composed of a hybrid system based on an 800 kg target mass of...

Measurements that exploit electroweak boson scattering processes have become increasingly common at the Large Hadron Collider in the last few years. In this talk, we present the study of the electroweak Zy production via both two neutrino and lepton final states. In addition, we present precision differential cross-section measurements of WW production in association with at least one jet. We...

Various Supersymmetry (SUSY) scenarios, including split SUSY and anomaly or gravity-mediated SUSY-breaking scenarios, lead to signatures with long-lived particles. Searches for these processes may target either the long lived particle itself or its decay products at a significant distance from the collision point. These signatures provide interesting technical challenges due to their special...

The High-Luminosity Large Hadron Collider (HL-LHC) is expected to deliver an integrated luminosity of up to 3000 fb$^{-1}$. The very high instantaneous luminosity will lead to about 200 proton-proton collisions per bunch crossing (“pileup”) superimposed to each event of interest, therefore providing extremely challenging experimental conditions. Prospects for selected topics in the SM and...

than that of the Higgs boson. The latest ATLAS results on searches for such resonances in final
states with leptons and photons based on pp collision data collected at 13 TeV will be

We present the first search for a light scalar arising from the decay of a B meson at CMS enabled by the novel technique of data scouting. In order to explore otherwise inaccessible phase space at low dimuon mass and non-zero displacement from the interaction point, a dedicated high rate dimuon trigger stream is used. No significant excesses are found and stringent constraints set on a wide...

In the list of interesting isotopes to be measured, Indium-115 is one of the most suitable due to the relatively high Q-value (497.954 keV) and half-life (4.41 $\times$ 10$^{14}$ yr).
We propose to exploit a cryogenic... -
