Anomalous U(1) Symmetry and Proton Decay
Recently, a new mechanism, which explains why three gauge coupling constants meet at a scale in the minimal supersymmetric standard model, has been proposed in a scenario of grand unified theories (GUT) with anomalous U(1)A gauge symmetry. It is non-trivial that although there are a lot of superheavy fields whose mass scales are below the unification scale, the mechanism explains the fact by us...
متن کاملThe Origin and Status of Spontaneous Symmetry Breaking
From its inception in statistical physics to its role in the construction and in the development of the Brout-Englert-Higgs mechanism in quantum field theory, the notion of spontaneous symmetry breaking permeates contemporary physics. The discovery at the LHC of the BEH boson would confirm the mechanism and promote the quest for unified laws of nature. These topics are reviewed with particular ...

15 صفحه اولTHE FRANK KINETIC MODEL FOR SPONTANEOUS CHIRAL SYMMETRY BREAKING WITH VARIABLE CONCENTRATION OF THE ACHIRAL SUBSTRATE
This paper considers the possibility of spontaneous transition of aracemic mixture (composed of equal amounts of two enantiomeric species, say L and D) into a monochiral state (in which only one enantiomer, say L, is present). Transitions of this kind have been recently experimentally observed. A plausible approach to this phenomenon is a model put forward by Frank, based on simple laws of ...

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
