About three decades after the first experiments on deep inelastic lepton hadron scattering began to investigate the structure of hadrons, the history of this fruitful field of particle physics continues in the broad spectrum of research performed at the electron and positron proton collider HERA at DESY, where the multipurpose detectors ZEUS and H1 access ep scattering at a center of mass energy of 300 GeV and explore as yet uncharted kinematic realms of deep inelastic scattering. After the first years of data taking at HERA, each of the experiments has collected a total of roughly 40 pb 1 of e+p data, yielding sensitivity to deep inelastic e+p interactions at high four momentum transfers, Q2, where typi cal cross sections drop into the subpicobarn regime. This kinematic domain is characterized by electroweak unification, manifesting itself most markedly in the neutral and charged current cross sections, which approach an equal order of magnitude as Q2 rises above the square of the W and Z masses. Consequently, HERA allows, for the first time, studies of both types of pro cesses simultaneously with the same initial state conditions and in the same detector, and thus we can investigate the interplay of electroweak and strong forces governing the respective cross sections.

While preparing for Class XII Board Exams, many students often burn the midnight oil by the sidewise preparation of JEE Mains which is the most reputed Engineering Entrance Exam in India conducted by The Central Board of Secondary Education (CBSE). As the students are well-known about the syllabus of this exam which appears tough by the inclusion of subjects like Physics, Chemistry and mathematics, the book shown in the right side is of great help to cope up its difficulty level this year. Titled ‘17 Years’ JEE MAIN Chapterwise Chemistry’ the book is a revised version and provides the detailed solutions on 20 chapters of Chemistry from 2002 to 2018. The manner in which the solutions have been made is easy to grasp. For self-evaluation, 10 Mock Tests is attached in the book along with free Online Practice as well to suit the students’ comfortability. Also, Solved Papers of Previous Years’ Questions (2015-2018) is charted along the book to familiarize students with the exam pattern. Designed as per the students’ perspective, it is a premium book to support the dream of leading success in the upcoming JEE MAIN. Table of ContentSome Basic Concepts of Chemistry, Sates of Matter, Atomic Structure, chemical Bonding, Thermodynamics, Solutions, Equilibrium, Redox Reactions and Electrochemistry, Chemical Kinetics and Surface Chemistry, Periodicity of Elements, Principles and Processes of Metallurgy, Hydrogen, s and p Block Elements, d and f Block Elements and Coordination Chemistry, Environmental Chemistry, General Organic Chemistry, Hydrocarbons and their Halogen Derivatives, Organic Compounds Containing Oxygen (Alcohols, Ethers, Aldehydes, Ketones, Carboxylic Acids and their Derivatives), Organic Compounds Containing Nitrogen (Amines and Diazonium Salts), Polymers and Biomolecules, Analytical Chemistry and Chemistry in Everyday Life, Practice Sets and Solved Papers for JEE MAIN.

This book is a rare jewel, describing fundamental research in a highly dynamic field of subatomic physics. It presents an overview of cross section measurements of deeply virtual Compton scattering. Understanding the structure of the proton is one of the most important challenges that physics faces today. A typical tool for experimentally accessing the internal structure of the proton is lepton–nucleon scattering. In particular, deeply virtual Compton scattering at large photon virtuality and small four-momentum transfer to the proton provides a tool for deriving a three-dimensional tomographic image of the proton. Using clear language, this book presents the highly complex procedure used to derive the momentum-dissected transverse size of the proton from a pioneering measurement taken at CERN. It describes in detail the foundations of the measurement and the data analysis, and includes exhaustive studies of potential systematic uncertainties, which could bias the result.
