Antikaon-induced K1(1270)+ meson production on nuclei near threshold

We study the inclusive strange axial-vector meson $K_1(1270)^+$ production in ${K^-}A$ reactions at near-threshold laboratory incident antikaon momenta within a nuclear spectral function approach, which describes incoherent direct $K^-$ meson--proton ${K^-}p \to {K_1(1270)^+}\Xi^-$ processes and accounts for three different options its in-medium mass shift (or effective scalar potential) central density $\rho_0$. calculate absolute differential total cross sections of mesons on $^{12}$C $^{184}$W target nuclei angles 0$^{\circ}$--45$^{\circ}$ by with 2.5, 2.8 3.5 GeV/c, are close to threshold momentum ($\approx$ 2.95 GeV/c) off free proton rest. The intrinsic properties carbon tungsten have been described terms their functions, take into account protons energies separation from considered nuclei. show that (absolute relative) antikaon-induced initial not far -- $\sim$ 2.8--3.5 there is yet no strong drop strength, reveal distinct sensitivity changes mass, studied paper, both low-momentum (0.1--1.0 full-momentum ranges. This would permit evaluating this shift. Experimental data necessary aim can be obtained dedicated experiment J-PARC Hadron Facility.
