Mass bounds in the standard model.

چکیده
Nonperturbative triviality and vacuum stability mass bounds are obtained for the Higgs scalar and top quark degrees of freedom in the standard electroweak model using Wilson renormalization group techniques. Particular attention is given to the effect of the generalized top Yukawa coupling on the scalar mass upper bound.

ضریب گشتاور مغناطیسی لپتون باردار در فضا- زمان ناجابهجایی
The g-factor of the charged leptons has always been considered by many physicists, both experimentaly as well as theoretically. In fact the electron and muon g-factor play the main role in testing the QED as well as the standard model. Meanwhile, there is a discrepancy between the standard model prediction of the muon anomalies magnetic moment and its experimental determination as large as (25...
متن کاملBounds on the Higgs Mass in the Standard Model and Minimal Supersymmetric Standard Model
We present bounds on the Higgs mass in the Standard Model and in the Minimal Supersymmetric Standard Model using the effective potential with nextto-leading logarithms resummed by the renormalization group equations, and physical (pole) masses for the top quark and Higgs boson. In the Standard Model we obtain lower bounds from stability requirements: they depend on the top mass and the cutoff s...
متن کاملExact maximum coverage probabilities of confidence intervals with increasing bounds for Poisson distribution mean
A Poisson distribution is well used as a standard model for analyzing count data. So the Poisson distribution parameter estimation is widely applied in practice. Providing accurate confidence intervals for the discrete distribution parameters is very difficult. So far, many asymptotic confidence intervals for the mean of Poisson distribution is provided. It is known that the coverag...
متن کاملNeutralino Mass Bounds in the Next–To–Minimal Supersymmetric Standard Model
We analyze the experimental data from the search for new particles at LEP 100 and obtain mass bounds for the neutralinos of the Next–To–Minimal Supersymmetric Standard Model (NMSSM). We find that for tanβ ∼>5.5 a massless neutralino is still possible, while the lower mass bound for the second lightest neutralino corresponds approximately to that for the lightest neutralino in the Minimal Supers...
متن کاملImpacts of Premium Bounds on the Operation of Put Option and Day-ahead Electricity Markets
In this paper, the impacts of premium bounds of put option contracts on the operation of put option and day-ahead electricity markets are studied. To this end, first a comprehensive equilibrium model for a joint put option and day-ahead markets is presented. Interaction between put option and day-ahead markets, uncertainty in fuel price, impact of premium bounds, and elasticity of con...
