Ds Meson

In this paper, we study the mass spectra of Ds mesons, such as Ds, [Formula: see text] and Ds1. In the simulation, we use Nf = 2 twisted mass lattice QCD gauge configurations generated by the European Twisted Mass Collaboration (ETMC). The simulation is performed on lattices with lattice spacings a = 0.067 fm and lattice size 323×64, and a = 0.085 fm and lattice size 243×48, respectively. Our numerical results for the mass spectra of Ds mesons reached impressive agreement with the experimental data.

The production cross-section of the beyond the standard model (BSM) scalar boson (S boson) have been considered it the article. Scalar boson produced via photon fusion reaction in the deep inelastic scattering of a charged particle (proton or electron) on heavy nucleus of the target. This process is one of the possible mechanisms of BSM boson production at the SHiP (Search for Hidden Particles) experiment at the CERN LHC and may be dominating among others processes due to large nuclear charge. Previously [1], the amplitude and the production cross-section of this reaction were found. The found cross-section was analyzed for the case of proton scattering on the lead nucleus and compared with the production cross-section in the decay of Ds meson. In this paper we make estimate of the process more accurate and consider also electron-nucleus scattering. It was found that the photon fusion reaction pZ \to S may be effective only in the case of massless S boson.
