J-PARC Heavy Ion project (J-PARC-HI) is a future fixed target experiment to study the properties of the dense matter created by the heavy-ion collisions with 1–12[Formula: see text]AGeV/[Formula: see text] at J-PARC. This project aims to search for the QCD phase boundary and its critical endpoint and to study the equation of state of the dense matter at J-PARC. For this purpose, the high-intensity beam and the precision detector with high-speed DAQ are necessary. J-PARC will be upgraded to produce the world’s highest intensity of heavy-ion beam by adding a new compact heavy-ion linac and a booster ring and utilizing the existing RCS and MR synchrotrons. We will construct the multi-purpose spectrometer with a large acceptance to measure hadrons, dileptons and photons, and their correlations and fluctuations. In these proceedings, we will report the current status of the project, the design of the detector configuration, and detector R&D.

The Nuclotron-based Ion Collider facility (NICA) is a new high luminosity machine which is under construction in Dubna (Russia). Heavy-ion collisions at the NICA are well suitable to investigate multiple problems of strongly interacting matter, including its Equation of State, phase transformations, modifications of hadron properties in dense medium, as well as critical phenomena. The MPD detector is a spectrometer with a large uniform acceptance capable of momentum measurement and particle identification in the high multiplicity environment of heavy-ion interactions. In this paper, the MPD performance to measure the hyperon production and the excitation function of the kaon-to-pion ratio in Au[Formula: see text]Au collisions at NICA energies is reported.

Alpha decay (AD) and spontaneous fission (SF) half-lives of superheavy nuclei [Formula: see text] have been studied within the density-dependent cluster model. The alpha-nucleus potentials were calculated using the double-folding model with the realistic M3Y nucleon–nucleon interaction. To calculate nuclear half-lives, several semi-empirical formulas were used in addition to the Wentzel–Kramers–Brillouin (WKB) approximation. The calculated AD half-lives agree well with the values computed by the analytical formulas of Royer, the semi-empirical formula of Poenaru et al. and the Viola–Seaborg systematic. To identify the mode of decay of these nuclei, the SF half-lives were calculated using the semi-empirical formula given by Xu et al. The results show that among the isotopes studied, isotopes [Formula: see text] can be survived from the SF and have a half-life greater than [Formula: see text][Formula: see text](s). The study predicts [Formula: see text] chains from isotopes [Formula: see text], [Formula: see text] chains from isotopes [Formula: see text], [Formula: see text] chains from isotopes [Formula: see text] and an AD from [Formula: see text]. These isotopes have a half-life long enough to be synthesized in the laboratory. Also, in the decay chains of these isotopes, it is observed that the nuclei [Formula: see text] have higher half-lives than their neighbors. The neutron numbers corresponding to these isotopes are [Formula: see text] indicating the magical or semi-magical behavior of these numbers, which is in good agreement with the research results.

We have studied systematically the alpha decay and cluster radioactivity half-life of heavy [Formula: see text]Mendelevium ([Formula: see text]) isotopes. The alpha decays from Md isotopes have been studied within the framework of Coulomb and proximity potential model using 14 different versions of nuclear potentials. Also, we have studied the half-lives of alpha decay of Md nuclei within the nuclear potentials generalized liquid drop model (GLDM) and also within GLDM with modified different nuclear potentials, namely proximity potential 2010, 1977, 1988, 2000 and 2002. Moreover, the half-lives of the [Formula: see text]-decay and cluster radioactivity calculated using the Universal formula for cluster decay (UNIV) of Poenaru et al., the Universal decay law (UDL) of Qi et al. and the Unified formula of half-lives for both the [Formula: see text]-decay and cluster radioactivity (UFADCR) of Ni et al. and found to be in good agreement. Our results have been compared with experimental data and demonstrate the acceptability of the approach. Among the different proximity potentials, GLDM with proximity 1977 version (GLDM[Formula: see text][Formula: see text][Formula: see text]P77) ([Formula: see text]) provides the best description for alpha decay studies with low deviation.
