Electric dipole moments of elementary particles Essay

Electric dipole moments of elementary particles - Essay Example A significant increase in experimental sensitivity surged with over 106 factor4 improvement. Figure 1 below shows an impressive breakthrough in said improvement in the experimental sensitivity. This improvement was for about 8 years.5 Yet, despite all these improved pursuits, no electric dipole moment was observed. Why do some scientists still spend so much time and effort looking for an EDM, something that is almost deemed a lost cause? Lamareoux and Golub6 believe that the reason why many physicists are quite obsessed in in searching for the EDM is that the observation of a non-zero neutron electric dipole moment is proof of time reversal violation that goes over and beyond the electro-weak interactions called â€Å"Standard Model†. A vital point is that the standard model predictions of time reversal violation’s magnitude are not consistent with the existing ideas about the formation of our universe. The production of what is presently seen as matter/antimatter asymm etry needs time reversal violation that has many orders of magnitude more than what is forecasted by the standard model. Figure 1. Sensitivity of neutron EDM experiments over time. On the left of the graph are some theoretical predictions of the magnitude of the neutron EDM. The electric dipole moments could easily offer to the world of physics one of the, if not the most thrilling prospects for its progress, particularly in particle physics. This could easily spell a bright future awaiting prospective experimentations that has something to do with the EDM calculations. Golub and Huffman7 has been very precise on what physicists and scientists expect to find when it comes to the search for neutron electric dipole moments by saying that such search for nEDM could easily represent a good hope for understanding and learning Physics well beyond the Standard Model (SM) since finding any non-zero neutron electric dipole moment would be a strong proof of the breakdown of the SM. The C, P a nd T The reversal of space coordinates, or the so-called parity P, T or the time reversal invariance and C, the charge conjugation are the three significant symmetry principles in the field of nuclear science. In particle physics, these three have a crucial role in understanding weak forces and weak interactions. These 3 symmetries are also the main points in understanding if a nucleus is behaving differently when the spatial configuration becomes reversed (P),or if time’s direction is made to run in a backward direction instead of the usual forward direction (T), or should the nucleus’ matter particles are changed to antimatter particles (C).†8 In a CP symmetry, the charge conjugation turns a particle into its reverse or its anti-particle. Likewise, parity creates an object’s mirror image. It has been an accepted fact in science that physical laws are unchangeable or invariant when undergoing parity transformation. Time, charge and space are nuclear prope rties that are reserved or reflected in mirror-like changes in symmetry properties. In the natural universe, it is but expected that mirror symmetries or inverses to exist. Since parity symmetry is valid for all reactions that involve strong forces and electromagnetism, the fundamental conservational laws such as conservation of momentum and conservation of energy also include parity conservation. However, two physicists, Chen Ning Yang and Tsung-Dao Lee, contradicted

The Broadway Cafe Research Paper Example | Topics and Well Written Essays - 1000 words

The Broadway Cafe - Research Paper Example The researcher states that one of the significant issues faced by the Broadway Cafà © has been that it does not have a computer system. In the modern day context, computers have significantly enhanced the way the companies operate in their respective industries. There has been significant advancement in technology, thus, the businesses that do not make use of the information system technology are at disadvantage in comparison to their competitors. By installing information system technology in Broadway Cafe, the orders can be recorded in the computer systems. The management will be capable of recording all the orders in the system as this will reduce the time required for taking orders and, therefore, the management will be able to pay due attention to other activities of the business. If the company is capable of managing its operations successfully then in such circumstances, the sales and the profitability of the company can be enhanced. It will permit the company to cut expenses because by updating information technology in an organization, there will be lesser requirement of employee force. Also, the names of the recipes for the baked goods and soups may be stored in the computers. E-Business is applied broadly in modern day business context. It is used to facilitate companies though the use of internet and communication technologies. It would be beneficial for Broadway Cafe to make use of internet as one of the significant tools for the purpose of ordering the goods and services. It is crucial for the company to create its own website via which it can trade its goods and services online and reach wider number of customers. It is because of the e-business technologies that Broadway Cafe will be capable of offering its customers with greater customer service, increase its sales volume, streamline its business processes and minimize the rising costs (Department of Jobs, Enterprise and Innovation, 2012). Creation of Online Community By creating online commun ity, Broadway Cafe will be capable of understanding the needs, interests and desires of the customers and will also be capable of connecting with other people who share similar interests. Facebook and Twitter are considered to be well known social networking sites that connect millions of people. Therefore, if Broadway Cafe is capable of creating its page in these sites then it will be able to make a large number of people aware about its products and services. Wireless Network The conventional network concept of the wired users is becoming obsolete. It is because of the increasing use of the wireless LANs, the data can be easily accessible to the users and, therefore, it may lead to productive and effective workforce. By installing wireless network in the Cafe, customers will be capable of accessing internet in their laptops and will be capable of working effectively. The customers may prefer spending prolonged hours within the cafe. This will have a significant impact upon the sal es and profitability of the company (Golden West Technology & Internet Solutions, 2012). CRM to Implement Marketing Campaigns and Sales Strategies In order to identify the ever-increasing customer demands, most of the companies in the recent times tend to implement a customer relationship management strategy so that it can administer the customer-facing methods of their business.
