1. Seminar topic: “Thermodynamic characteristics of particles produced in π^–C interactions at 40 GeV/c as a function of the cumulative number and the van der Waals equation of state”

   Authors: M. Sovd, Ts. Baatar, A. I. Malakhov, B. Otgongerel, B. Batgerel and
   G. Sharkhuu

   Speaker: Ts. Baatar.

   Abstract:
   
   In this paper, we determined constants a and b of the van der Waals equation of state using the experimentally obtained critical parameters T_c, V_c and P_c for π^– mesons and protons from π^–C interactions. We also analyzed p-V diagrams.

2. Seminar topic: “Two different distance scales of q² and V_QCD potential of protons from π^–C interactions at 40 GeV/c”

   Authors: Ts. Baatar, A. I. Malakhov, B. Otgongerel, M. Sovd, G. Sharkhuu

   Speaker: Ts. Baatar.

   Abstract:
   
   In this paper, we expressed the formula for the four-momentum squared q² as a function of two different distance scales r₁ and r₂. This procedure necessitates to take into account an additional derivative from the formula for q² (or the running of α_s(q²)). We calculated the force using the potential V_QCD(r₂). The impact of r₂ parameter to the force is also studied.

3. Seminar topic: “On the possibility of pion condensation from π_–C interactions at 40 GeV/c”

   Authors: M. Sovd, Ts. Baatar, A. I. Malakhov, B. Otgongerel, B. Batgerel,
   G. Sharkhuu

   Speaker: Ts. Baatar.

   Abstract:
   
   In this paper we consider the possible observation of the π^– meson condensation on the basis of the dependence of the temperature (T) as a function of the target mass (m_t) and the chemical potential (μ_sec(μ_B,T)) from π^–+C interactions at 40 GeV/c.
