Long-Range Interactions of the Ball

In model independent way considered long-range interactions of the macroscopic objects under assumption that any particle of this objects interact with probe particle as $ A/r^n$. Also presented model-independent corrections to the Coulomb energy levels from regularised version of the potential $ A/r^n$.

Axial Symmetry and Bound States of Particles with Anomalous Magnetic Moment

We consider bound states of fermions with an anomalous magnetic moments in the field of charged cylinder.Also we obtain second order equations for axially symmetric $Z_0(r)$-boson field, radial axially symmetric magnetic field, obtain second order equations for case of bound states of fermions in the radial electric and magnetic fields.

P-Parity Violating Bound States of Particles with Anomalous Magnetic Moment

We consider bound states of fermions with an anomalous magnetic moments(neutrinos,neutrons) in radial electric and magnetic field of monopole.In case of radial magnetic field the interaction $\vecΣ\vec{H}$ violates P-parity and for this reason we must use the method of (hep-ph/9901248) where both components of spinor considererd as a linear combination of spheric spinors with different P-parity. Also we apply pseudoscalar-like interaction (2) obtained in \cite{DF} to monopole case and add it in Dirac equation.We obtain the system of differential equations for radial functions which define energy levels of fermions with anomalous magnetic moments in the presence of monopole.

Lepton -Neutron Bound States

We consider lepton-neutron (and lepton-antineutron) bound states and resonances which appear due to spin-spin, spin-orbital interactions,neutron polarization by muon. Our analis is also true for any system which include one charge and one neutral particle with finite size e.g. $π^0μ^{\pm}$-bound states.We consider also cylindrically symmetric bound states and resonances of particles with anomalous magnetic moments.

Doubly Charged Fermions Bound States,Vector Bosons Bound States

We consider positronium-like bound states of doubly charged fermions.We consider also $P(CP)$-parity violation in positronium like system (including quarkonium and lepton antilepton bound states and mesoatoms) which take place due to $Z^0$-bosons or Higgs bosons exchange.By model independent way we consider also vector bosons bound states in the Coulomb and Higgs potential and have shown that in the presence of the Higgs potential effective potential become less singular and in this case fall down on the center is absent.Vector bosons energy levels in the magnetic field are considered. Considered magnetism of electron gas in the finite volume.

Electroweak Lepton-Lepton and Lepton-Antilepton Bound States

In model independent way we consider the possibility of the existence of fermion-antifermion, fermion-fermion bound states which appear due to $γ, Z^0(W^{\pm}$-bosons and scalar, pseudoscalars exchanges including radiative corrections. Our consideration includes the case where at least one particle in the bound state is Majorana fermion or scalar.This paper considers various types of bound states of particles contained in various extensions of the Glashow-Weinberg -Salam model. We calculate long-range forces induced by photonic, gluonic and fermionic loop corrections in scalar (pseudoscalar) exchange.

$R$-Parity Violation and Scalar Leptons Production at Lepton- Antilepton Colliders

In the framework of models with R-parity violation, scalar neutrinos and scalar leptons production in the processes $l_i^+l_j^-\to\tilde ν_{k,L} Z^0$ and $l^+_il^-_j\to \tilde{l}^{\mp}_{k,L}W^{\pm}$ is considered.We also consider within the Minimal Supersymmetric Standard Model Higgs bosons production in the processes $μ^+μ^-\toH_i^0Z^0$, $μ^+μ^-\to H^{\pm}W^{\mp}$.

R-Parity Violation and Photon-Neutrino Interactions

In the framework of the supersymmetric theories with R-parity violation we consider the process $γγ\to ν_i \bar{ν_j}$ and its contribution into energy loss from the stars.Under some conditions the studied contribution exceeds the standard model contribution to the same process.

Higgs Bosons Production with Photons at Lepton-Antilepton Colliders

By model independent way scalar and pseudoscalar neutral Higgs boson production with photon in the tree process $μ^+μ^- \to H^0 γ$ are considered.For the Standard Model and Minimal Supersymmetric Standard Model cases numerical estimates are obtained.The model independent flavour changing Higgs bosons production in the tree processes $e^+e^-,μ^+e^- \to H^0_{fc} γ$ is also considered.

Heavy Majorana Neutrino Decays and CP-Parity Violation

In the framework of the left-right symmetric model the CP-parity violation has been studied in heavy Majorana neutrino decays $N\rightarrow e^{\mp} μ^{\pm} n$. The numerical estimates of CP-asymmetry for different masses of neutrino and $W_{R}^{\pm}$-boson were obtained. The possibility to detect this phenomenon at high energy colliders is mentioned.
