We combine a recent construction of Becchi-Rouet-Stora-Tyutin (BRST)-invariant, nonlinear massive gauge fixing with the background field formalism. The resulting generating functional preserves background-field invariance as well BRST quantum manifestly. features BRST-invariant mass parameters for and ghost fields. formalism employs Nakanishi-Lautrup which is part gauge-fixing sector thus shoul...
We derive the off-shell nilpotent and absolutely anticommuting (anti-)BRST symmetry transformations for any arbitrary D-dimensional St$\ddot u$ckelberg-modified massive Abelian 3-form theory within framework of augmented version superfield approach (AVSA) to Becchi-Rouet-Stora-Tyutin (BRST) formalism where, in addition horizontality condition (HC), we exploit theoretical strength gauge invarian...
this research concentrates on the lithostratigraphy, biostratigraphy, microfacies and sedimentary environment of the asmari and gachsaran formations at southwest firuzabad. the thickness of the studied section in all 608.95 meters that 220.8 meters belong to the asmari formation and 387.95 meters belong to the gachsaran formation (champe and mol members). in the study area, the asmari formation...
abstract birbery and corruption and other criminal and as such is one of social phenomena , and i can firmly say that society is protected and safe from harm , this is criminal . eache community is familiar with these crimes and the crime associated ( direct or indirect ) with the political economic , social , and cultural beliefs and religious issues , especially with the community . admitted...
this dissertation has six chapter and tree appendices. chapter 1 introduces the thesis proposal including description of problem, key questions, hypothesis, backgrounds and review of literature, research objectives, methodology and theoretical concepts (key terms) taken the literature and facilitate an understanding of national security, national interest and turkish- israeli relations concepts...
increasing academic and professional language demands around the world are not a deniable fact. the purpose of this study was to investigate english language needs and communication needs of the chemistry students at master and ph.d. levels at the iranian universities. in this research, different methods were used including un-structured interview, structured interview, and two sets of question...
By constructing a nilpotent extended BRST operator ¯ s that involves the N=2 global supersymmetry transformations of one chirality, we show that the standard N=2 off-shell Super Yang Mills Action can be represented as an exact BRST term ¯ sΨ, if the gauge fermion Ψ is allowed to depend on the inverse powers of supersymmetry ghosts. By using this nonanalytical structure of the gauge fermion (via...
In some of the physically interesting gauge systems, we show that application Noether theorem does not lead to deduction Becchi-Rouet-Stora-Tyutin (BRST) and anti-BRST charges obey precisely off-shell nilpotency property despite fact these are $(i)$ derived by using nilpotent (anti-)BRST symmetry transformations, $(ii)$ generators above continuous $(iii)$ conserved w.r.t. time-evolution due Eul...
