Level-Crossing in the Instanton-Anti-Instanton Valley
We study the level crossing of the fermion system described by the euclidean Dirac Hamiltonian in the valley background. One chiral fermion level is shown to cross twice the zero value in the case of well-separated instanton-antiinstanton background. Below a critical separation, however, level crossings are absent. The phenomenon can be interpreted as the transition to a gauge field configurati...
متن کاملthe effect of authentic listening materials on the listening proficiency of efl learners in the intermediate level
having conducted the experiment and analysed the data, the researcher computed the groups mean scores and variances for the test relating to the research question. as the final atep, a t-test was conodonted for the hypothesis. as noted earlier, the significance level was determined at .05 and .01 respectively. the observed t-value was higher than the critical t-value at. 5 and .01 levels. conse...

where √ s is c.m. energy of the process, Esp ≈ 4 √ 6πmw g ≈ 16 TeV energy of sphaleron [7]. The first term in ”Holy Grail” function F (ε) is ’t Hooft suppression factor [1], the second corresponds to the multiple W and Higgs bosons production in Gauss approximation [4, 5], the third is a contribution of tree boson graphs [8, 9]. Boson loops [10] and fermion contribution [11] are accumulated in ...
متن کاملthe effect of using critical discourse analytical tools on the improvement of the learners level of critical thinking in reading comprehension
?it is of utmost priority for an experienced teacher to train the mind of the students, and enable them to think critically and correctly. the most important question here is that how to develop such a crucial ability? this study examines a new way to the development of critical thinking utilizing critical discourse analytical tools. to attain this goal, two classes of senior english la...
A Z2 Classification for 2D Fermion Level Crossing
We demonstrate that the number of fermionic zero modes of the static 2-dimensional Dirac operator in the background of SU(2) static gauge-Higgs field configurations is a topological invariant modulo four. Static configurations which are everywhere odd under parity with even-parity pure gauge behaviour at infinity admit 4n, n ∈ Z, zero modes of the Jackiw-Rebbi (JR) type. Odd-parity configuratio...
