Gauged linear sigma models with C^m-valued scalar fields and gauge group U(1)^d, d \leq m, have soliton solutions of Bogomol'nyi type if a suitably chosen potential for the scalar fields is also included in the Lagrangian. Here such models…
In some supersymmetric extensions of the Standard Model fairly light superpartner of t-quark is predicted, which may form bound states - stoponiums. We estimate potentials of TESLA linear collider in search for stoponium, considering the…
We consider the properties of the ground state of bottomium. The $\Upsilon$ mass is evaluated to two loops, and including leading higher order [$O(\alpha_s^5\log\alpha_s)$] and $m_c^2/m_b^2$ corrections. This allows us to present updated…
Asymptotic levels of the A $^1\Sigma_u^+$ state of the two isotopomers $^{39}{\rm K}_2$ and $^{39}{\rm K}^{41}{\rm K}$ up to the dissociation limit are investigated with a Doppler-free high resolution laser-spectroscopic experiment in a…
The Belle experiment at KEK accumulated a $121.4~{\rm fb}^{-1}$ sample of $e^+e^-$ collisions at the $\Upsilon(5S)$ resonance. This sample provides ample opportunity for improving the understanding of both the properties of $B_s$ mesons and…
We derive new limits on light stops from diboson resonance searches in the $\gamma\gamma$, $Z \gamma$, $ZZ$, $WW$ and $hh$ channels from the first run of the LHC. If the two-body decays of the light stop are mildly suppressed or…
Under the Initial Single Pion Emission mechanism, we study the hidden-bottom dipion decays of $\Upsilon(11020)$, i.e., $\Upsilon(11020)\to \Upsilon(nS)\pi^+\pi^-$ $(n=1,2,3)$ and $\Upsilon(11020)\to h_b(mP)\pi^+\pi^-$ $(m=1,2)$. We predict…
