When the Standard Model is extended with extra scalar particles, they mix to form physical mass eigenstates. One of these eigenstates is associated with the recently discovered 125 GeV Higgs boson. If one of the other eigenstates is sufficiently massive, it may decay to two 125 GeV states, and thus provide significant contribution to the $pp \to hh$ cross section which in the Standard Model is...

Search for isobar-analog states of superheavy hydrogen isotopes 5-7H was performed among the high-excited states of helium isotopes 5-7He. The excited spectra were measured in stopped pion absorption by light nuclei. The experiment was performed at low energy pion channel of LANL with two-arm multilayer semiconductor spectrometer. The method of research is based on precise measurements of...

Search for rare cluster configuration in 14С nucleus was carried out in the correlation measurements of stopped pion absorption reaction π¯+ 14C → p + d + Х. For our analysis we took the data obtained in the experiment on the LANL accelerator (Los Alamos, USA) using the multilayer semiconductor spectrometer [1]. The analysis of the reaction was made via previously used method for the search of...

Results on the measurement of the spectra of p, d, t formed in the reaction of stopped pion absorption by atomic nuclei from the wide mass number range (6 < A < 209) are presented. Phenomenological model developed by us [1, 2] had allowed to calculate contributions of cluster absorption, preequilibrium and evaporation processes in the particle formation. A-dependences of primary particles...

The formation of high-multiplicity nuclear stars was observed upon irradiating nuclear track emulsions with ultrarelativistic muons [1-3]. Kinematical features studied in this exposure of nuclear track emulsions for events of the muon-induced splitting of carbon nuclei to three alpha particles are indicative of the nucleardiffraction interaction mechanism. The irradiation of track emulsions...

Application of the nuclear track emulsion technique (NTE) in radioactivity
and nuclear fission studies is discussed. It is suggested to use a HSP-1000
automated microscope for searching for a collinear cluster tri-partition of heavy
nuclei implanted in NTE. Calibrations of α-particles and ion ranges in a novel NTE
are carried out. Surface exposures of NTE samples to a Cf-252 source...
