 Searches for lepton flavor and lepton number violation in $K^+$ decays with NA62 / Duk, V (INFN, Perugia) /NA62 Collaboration The NA62 experiment at the CERN SPS provides unique opportunity to study rare and forbidden decays of $K^{+}$ mesons. Using the data collected in 2017 a search for the lepton number violating decays $K^{+}$ → $\pi^-$ $\mu^+$ $\mu^+$and $K^{+}$ → $\pi^-$ $e^{+}$ $e^{+}$ has been performed.

 Charged Kaons semi-leptonic form factors from NA48/2 / Lamanna, G (Pisa U.) /NA48/2 Collaboration The NA48/2 experiment collected unprecedent statistics of charged kaon decays in 2003 and 2004. The main purpose of the experiment was to measure direct CP violation in kaon decays to three pions while an extensive physics program was carried out together with the main goal.

 First observation and study of the $K^{\pm} \rightarrow \pi^{\pm} \pi^0 e^+ e^-$ decay with the NA48/2 experiment at CERN / Bloch-Devaux, B (Turin U.) /NA48/2 Collaboration The first observation of the rare decay $K^{\pm} \rightarrow \pi^{\pm} \pi^0 e^+ e^-$  is reported by the NA48/2 experiment at CERN, based on 4919 candidates with 4.9% background contamination. From the analysis of 1.7 × 10$^{11}$ kaon decays collected in 2003–2004, the branching ratio in the full kinematic region is measured to be BR ($K^{\pm} \rightarrow \pi^{\pm} \pi^0 e^+ e^-$)= (4.24 ± 0.14) × 10$^{-6}$.

 New Result on $K^+ \rightarrow \pi^+ \nu \overline{\nu}$ from the NA62 Experiment / Ruggiero, G (Lancaster U.) The NA62 experiment at the CERN SPS is designed to measure the branching ratio of the $K^+ \rightarrow \pi^+ \nu \overline{\nu}$ with a decay-in-flight technique and took data in 2016–2018. The statistics collected in 2017 allows NA62 to achieve the best up–to–date single event sensitivity for $K^+ \rightarrow \pi^+ \nu \overline{\nu}$ corresponding to more than 2 Standard Model $K^+ \rightarrow \pi^+ \nu \overline{\nu}$ expected events.

 Two years’ test of a temperature sensing system based on fibre Bragg grating technology for the CMS GE1/1 detectors / CMS Muon Group Collaboration A temperature monitoring system based on fibre Bragg grating (FBG) fibre optic sensors has been developed for the gas electron multiplier (GEM) chambers of the Compact Muon Solenoid (CMS) detector. The monitoring system was tested in prototype chambers undergoing a general test of the various technological solutions adopted for their construction. [...] 2020 - 8 p. - Published in : J.

 The RICH detector of the NA62 experiment / Brizioli, F (INFN, Perugia ; Perugia U.) ; Lollini, R (INFN, Perugia ; Perugia U.) /NA62 Collaboration The RICH detector of the NA62 experiment is one of the key detectors to achieve the muon rejection needed in the search for the $K^+ \rightarrow \pi^+ \nu \overline{\nu}$ decay, performed by NA62. Since BR($K^+ \rightarrow \pi^+ \nu \overline{\nu}$) is higher than BR($K^+ \rightarrow \pi^+ \nu \overline{\nu}$ ) by more than 9 orders of magnitude, it represents one of the most relevant background contributions.

 Using LHC to Discover the Bilepton / Frampton, Paul H (Salento U. ; INFN, Lecce) We discuss a minimal and simple extension of the standardelectroweak model and discuss its uniqueness properties.Its most readily testable prediction is the existence of$|Q|= |L|= 2$ gauge bosons, bileptons, which decay intolike-sign lepton pairs. We discuss how a discoverycould be made at the LHC..
