Soft colour interactions and the diffractive structure function

Soft Colour Interactions and the Diffractive Structure Function

We discuss our model for soft colour interactions and present results on the diffractive structure function F D 2 (β, x IP , Q 2) and inclusive transverse energy flows, which agree with available HERA data. The observation of rapidity gap events at HERA [1, 2] has led to a renewed interest in diffractive phenomena and how they can be understood within QCD. In [3] we presented a new model for di...

Soft Colour Interactions and Diffractive DIS

The basic ideas and some results of the semiclassical approach to diffractive DIS are briefly described. In the production of high-p⊥ jets boson-gluon fusion is predicted to be the dominant partonic process. The p⊥-spectrum and the two-jet invariant mass distribution provide a clear test of the underlying ‘hard’ partonic process and the ‘soft’ mechanism of colour neutralization. The events with...

Soft Interactions and Diffractive Phenomena

the underlying structure of language proficiency and the proficiency level

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...

Soft Classification of Diffractive Interactions at the LHC

Multivariate machine learning techniques provide an alternative to the rapidity gap method for event-by-event identification and classification of diffraction in hadron-hadron collisions. Traditionally, such methods assign each event exclusively to a single class producing classification errors in overlap regions of data space. As an alternative to this so called hard classification approach, w...
