The $\ensuremath{\beta}$ decay of ${}^{53,54}$Ni, ${}^{52,53}$Co, ${}^{51}$Fe, and ${}^{50}$Mn was investigated via the fragmentation a ${}^{58}$Ni primary beam with an energy 68.6 MeV/u. proton-$\ensuremath{\gamma}$ coincidences ${}^{53}$Ni $\ensuremath{\beta}$-delayed proton emission were observed. Based on analysis coincidence events, it inferred that previous assignment excitation for isobaric analog state in ${}^{53}$Co may be problematic. half-lives these nuclei obtained, which...
In-situ hermiticity detection using Titanium dioxide (TiO 2 ) thin film resistors has been investigated for the first time.Titanium is widely used as an oxygen sensor, with accurate partial pressure reading at high temperatures.In addition to being sensitive room temperature, TiO were found be excellent gauges typical bonding pressures in range of 1 Torr 760 Torr.Combining sensitivity selectivity, constitute perfect solutions MEMS devices capped deficient environment sub-atmospheric...
We study the classical cosmic string solution in a theory with dynamical U(1) symmetry breaking. calculate energy per unit length of and compare it to that obtained model fundamental Higgs field. find predictions standard Abelian are quite stable towards addition higher dimension operators expected effective Lagrangian for order parameter breaking, at least small coupling constant $\ensuremath{\lambda}$.
Stability of the chiral soliton coupled with ρ meson which is quantized by taking breathing modes into account in addition to spin-isospin rotational examined on basis families trial functions. It shown that parity-conserving states are not ones minimum energies and solitons collapse through spontaneous parity-violating states. The decay paths represented a parameter profile
The presence of a heavy fermion doublet in the electroweak instanton probably leads to unsuppressed number nonconservation. By calculating numerically effective potential barrier with Minkowski space by using semiclassical approximation, it is shown that, if mass exceeds critical value [Formula: see text] TeV (for M H = W ), tunneling should be and decays violation. dependence on Higgs also presented.
The presence of a heavy fermion doublet fourth generation in the standard model would lead to anomalous decay with number non-conservation. path background electroweak instanton is demonstrated by numerical calculation. If mass exceeds critical value $m_f^{\rm cr}$=9.2 TeV (for $M_H=M_W$), it shown that there exists rapid semi-classical approximation. dependence on Higgs also presented.
For strong enough Yukawa coupling the electroweak standard model fermion finds it energetically advantageous to transform itself into a bound state in hedgehog background of Higgs field semiclassical approximation. By considering states give masses for lepton and quark, we found that all strongly constants tend an unitary constant. On other hand, $W$ $Z$ produced by keep almost no change.
