Tests of Quantum Chromodynamics in Exclusive E+e-and Ye Processes*

One of the most, important area.s of investigation in quantum chromodynamics are few-hod3, exclusive reactions initiated by electromagnetic initial states. such as e'e-i HH t+tt-> + ?H. and the two-photon processes 77-+ Hfi shown in Fig. 1. The simplicity. of the photon's couplings to the quark currents and the a.bsence of initial state hadronic interactions allows one to st,ud>. the process of...

historicizing in the contemporary fiction ("ma'soum-e panjm", "ayene-ha-ye dar-dar" va "barre-ye gomshode-ye ra'ie": a case study)

abstract the ancient history and culture of iran has been a main field of research for many writers in the contemporary times. among these writers is hushang golshiri. in many of his works, in fifth innocent and shazdeh ehtejab (prince ehtejab) in particular, he has paid great attention to history. the main question of the present study is to discuss how golshiri has dealt with story and myth i...

Seek and Ye Shall Find

This chapter proposes that search engines apply a verticalizing pressure on the WWW many-to-many information distribution model, forcing this to revert to a distributive model similar to that of the mass media. The argument for this starts with a critical descriptive examination of the history of search mechanisms for the Internet. Parallel to this there is a discussion of the increasing ties b...

On the modular curves YE(7)

Let E denote an elliptic curve over Q and Y E (7) the modular curve classifying the elliptic curves E over Q such that the representations of Gal(Q/Q) in the 7-torsion points of E and of E are symplectically isomorphic. In case E is given by a Weierstraß equation such that the c 4 invariant is a square, we exhibit here nontrivial points of Y E (7)(Q). From this we deduce an infinite family of c...
