How Well Do We Know the Electromagnetic Form Factors of the Proton?
نویسنده
چکیده
Recent measurements of recoil polarization in elastic scattering have been used to extract the ratio of the electric to the magnetic proton form factors. These results disagree with Rosenbluth extractions from cross section measurements, indicating either an inconsistency between the two techniques, or a problem with either the polarization transfer or cross section measurements. To obtain precise knowledge of the proton form factors, we must first understand the source of this discrepancy.

Welcome to virosphere
Viruses may seem alien, but they are the most abundant and, arguably, the most important organisms on Earth. They are found just about everywhere, from oceans and forests to the people around you and, of course, in and on you as well. This world of strange, quasi-living things has been dubbed the virosphere, and it is a mysterious one – we know less about viruses than any other life form. But t...
متن کاملMembrane fusion/repair in nerve cells: a biophysical application in spinal cord injuries regeneration
Cell membrane has a critical and vital role in functioning and existence of nerve cells that form central nervous system (CNS) in mammals. Disruption of nerve membrane that normally occurs following an accident injuring spinal cord is known to be the major cause of paralysis. In most occasions, spinal cord injuries are not leading to complete cut in spinal cord fibers but are known to cause cru...
متن کاملDeterminants of Subjective Well-Being; Do We Really Know What Makes People Happy? : A Study Among Rasht Dwellers as a Metropolis in North of Iran
Recently, along with traditional economic indicators, policymakers are increasingly dealing with subjective well-being (SWB) as an evaluation criterion of their performance and as an index for the population’s psychology health. This study tries to define different determinants of SWB with a focus on some specific aspects of the living area. Also, this article investigates outskirt-urban differ...
متن کاملSatisfaction Function in Present Undesirable Factors
Data Envelopment Analysis (DEA) is an efficient method to perform evaluation of units. In DEA we try to evaluate units with undesirable factors in input & outputs by satisfaction function, testing some models. On the other hand benefiting this concept, we can identify non-efficient units. Also we can recognize why these units are inefficient and calculate the reason of their inefficiency and ho...
