We revisit a recently proposed scale invariant extension of the standard model, in which the scalar bi-linear condensate in a strongly interacting hidden sector dynamically breaks scale symmetry, thereby triggering electroweak symmetry breaking. Relaxing the previously made assumption on U (N f ) flavor symmetry we find that the presence of the would-be dark matter candidate opens a new annihilation process of dark matter at finite temperature, such that the model can satisfy stringent constraints of the future experiments of the dark matter direct detection.

The calculation of the electrode model in the corona plasma discharge case has been carried out using the semi-ellipse line to plane (S-ELTP) configuration model in the air. The final focus of this research is to calculate the (I–V) current–voltage characteristics of the plasmas discharge. Part of the work in the (I–V) characteristics includes computational calculations and carrying out experimental activities. Experimental data include current vs voltage variations that occur at the time of plasma discharge. All the discharge processes are generated by a positive DC voltage source. The arrangement of the geometric configuration of the electrodes consists of two plates in the form of a half ellipse (active electrode) and a rectangular plate (passive electrode) in a mutually perpendicular position. The size variation of the active electrode includes variations of the small and large size plates with each plate having two variations in the distance between the two electrodes. The calculation concept of the electrode model is to insert the certain shape sharpness factor of k in the numerical calculation in the sharp electrode capacitance part. The k factor value is obtained by calculating the fitting between numerical simulation and research data. The research results prove that there is a fairly high level of conformity between numerical simulation and the research data. Simulation calculation for the (I–V) characteristic curve and its level of accuracy used Python GUI Programming.

In this report, we study the electro-optics effect on cooking oil to obtain the relative dissociation energy as a new single proposed parameter of oil quality. The sample was canola oil which had been heated in 0.5 hours, 2 hours and 4 hours. The light source used in the experiment was a green pointer laser with a wave length of 532 nm. The sample was applied to a potential difference from 0 to 9 kV to obtain the electro-optics effect in form of the change of the polarization angle Dq as function of potential difference DV. The relative dissociation energy was obtained from the fitting data of the relative Lenard-Jones potential energy curves represented by change of polarization per unit change of potential difference, Dq/DV. The result shows that the relative dissociation energy is reduced as the oil quality decreased after heated. The relative dissociation energy provides simple physical understanding about electro-optics effect on cooking oils. The study of electro-optics polarization that represents relative Lenard-Jones potential energy is a new but somewhat intuitive, which can be further improved and emphasized for grouping, mapping, and determining various cooking oil quality and halal food due to the lard contamination.

Terdapat beberapa ekstensi Model Standar dalam Fisika Partikel untuk menjelaskan pembentukan massa neutrino. Salah satu ekstensi yang paling sederhana adalah mekanisme Seesaw tipe I. Dalam mekanisme ini diperkenalkan neutrino right-handed yang tidak ambil bagian dalam interaksi lemah atau sering disebut juga dengan steril (Y=0). Pada tulisan ini, kami berusaha menuliskan penjabaran mengenai mekanisme ini.
