Sensitivity of the SHiP experiment to Heavy Neutral Leptons
SHiP Collaboration
Heavy Neutral Leptons (HNLs) are hypothetical particles predicted by many extensions of the Standard Model. These particles can, among other things, explain the origin of neutrino…
On the Sigma^0 --> Lambda^0 + gamma decay in the Effective quark model with chiral U(3)xU(3) symmetry
A. N. Ivanov, A. Ya. Berdnikov, Ya. A. Berdnikov +5
We analyse the angular distributions of the Sigma^0 --> Lambda^0 + gamma decay rate in the laboratory and in the rest frame of the Sigma^0 - hyperon in the dependence on baryon pol…
On the polarization properties of the charmed baryon Lambda^+_c in the Lambda^+_c -> p + K^- + pi^+ + pi^0 decay
A. Ya. Berdnikov, Ya. A. Berdnikov, A. N. Ivanov +3
The polarization properties of the charmed Lambda^+_c baryon are investigated in weak non-leptonic four-body Lambda^+_c -> p + K^- + pi^+ + pi^0 decay. The probability of this deca…
On the reactions p + p -> p + Lambda + K^+ and p + p -> p + Sigma^0 + K^+ near thresholds
A. Ya. Berdnikov, Ya. A. Berdnikov, A. N. Ivanov +3
The cross sections for the reactions of the strange production p + p -> p + Lambda + K^+ and p + p -> p + Sigma^0 + K^+ near thresholds of the final states p Lambda K^+ and p Sigma…
On the hadron production from the quark-gluon plasma phase in ultra-relativistic heavy-ion collisions
A. Ya. Berdnikov, Ya. A. Berdnikov, A. N. Ivanov +4
We describe the quark gluon plasma (QGP) as a thermalized quark-gluon system, the thermalized QGP phase of QCD. The hadronization of the thermalized QGP phase is given in a way res…
On the K^+_- meson production from the quark-gluon plasma phase in ultra-relativistic heavy-ion collisions
A. Ya. Berdnikov, Ya. A. Berdnikov, A. N. Ivanov +3
An abundance of the strangeness that can be induced in a thermalized quark-gluon plasma (QGP) is considered as a signal of the QGP phase appearing in the intermediate state of ultr…
