Abstract

Information related to deviants in the near future is often the case by a group of adolescents. Behavior that deviates from anxiety because of a problem in daily life. One way that is taught by Islam by listed in the Qur'an and hadith to reduce anxiety in a person is to do istighfar dhikr. Knowing the beta brain wave activity in anxiety and istighfar dhikr condition can be done using an EEG (Electroencephalogram). Beta waves are brain waves that are detected when a person feels anxious. Beta wave measurement method is calculated based on peaks or troughs per second on the beta signal type frequency (13-30Hz). The method in this research is an experiment with quantitative data collection. The sample used in this study were 8 students in Universitas Islam Negeri Walisongo Semarang with an age range of 20-23 years. The data analysis technique used is bivariate with Paired T-test. The results showed that the average beta wave in anxiety condition was 14.213 Hz and istighfar dhikr was 13.085 Hz. The result of the Paired t-test showed that p = 0.002 (p 0.05) indicating that the decrease in beta waves in the brain is very significant. It shows that istighfar dhikr can reduce anxiety in adolescents.

Abstract

The Standard Model is a model of particle physics in which one Higgs particle has been confirmed with a mass of 126 GeV. In 2016 some discoveries made it possible to have other scalar particles similar to the Higgs. The modified left-right symmetric model extends the standard model with an expanded scalar sector. There are ϕ_L and Δ_L left sector scalar particles, ϕ_L and Δ_L right sector scalar particles and two singlet η and ξ scalar particles. Therefore, this research objective is to analyze of the possibility of a Higgs interaction with other scalar particles. The method of this research is using a Feynman diagram to describe the interaction terms at the Higgs Potential. The interaction probability is sought using the Feynman rule for Toy Theory. The decay rate uses the Golden Rule. When the universe's temperature reaches the mass of η, the scalar becomes non-relativistic and decays into ϕ_L and ϕ_R. The scalar ξ is scattered into ϕ_L through the η scalar propagator and into ϕ_R. The scalars Δ_L and Δ_R do not decay, they only scatter into ϕ_L and ϕ_R. The η and ξ scalars have transformed into ϕ_L in the left sector and ϕ_R in the right sector, and only ϕ_L in the sectors are likely to be detected as the Higgs Standard Model.
