New Physics Essay - 775 Words

What is the (next accessible) scale of new physics? We do not have a clear answer. We are living through a challenging and exciting era, in sharp contrast to the situation in the past (half) century in physics. The discovery of the Higgs boson, the determination of the non-zero $\theta_ {13} $ neutrino mixing parameter, the first detection of gravitation waves, and many significantly improved experimental probes for new physics beyond the standard model mark the great triumphs of our understandings of nature. Profound puzzles of nature, such as hierarchy problem, dark matter, neutrino properties, matter-antimatter asymmetry, strong CP, flavor structure, etc., are actively being explored but yet remain to be solved. However, no clear†¦show more content†¦My research on supersymmetry~(SUSY) includes DM physics in conjunction with Higgs boson, SUSY particle searches in scenarios such as compressed spectra, stealthy SUSY and displaced SUSY with long-lived particles, as well as using the Higgs bosons as portals to SUSY particles. Moreover, I am experienced and interested in QCD and Jet observables at colliders in both traditional kinematics construction and Machine Learning methods. Furthermore, my research in studies of general resonances also stands out, such as colored resonances, $t\bar t$ resonances, $Z^\prime$ and $W^\prime$ through assorted asymmetries and electroweak radiation observables. Currently, I have pioneered in using unconventional on-shell interference effects to between signals and background amplitudes to probe new physics. I have identified several critical processes at the LHC and found these interesting on-shell interference effects not only an essential component of the precision programs but also unique probes for BSM physics. Whats more, I am working on using angular distributions in boosted $t\bar t$ system at the LHC and proposing new searches for exotic long-lived particle signatures in stop coannihilation DM scenario in the MSSM and a next to minimal dark matter model.

This concept is a great contender of quantum relativity mess theory, string theory and the theory of everything. In this essay, we visit these theories and provide a general view or opinion on the future of physics.

Towards the end of the 19th century physics was mostly thought to be at an apex. One man at the time, William Thomson Kelvin [cited by Glen Elert in The Physics Hypertextbook], said along the lines of â€Å"There is nothing new to be discovered in physics now. All that remains is more and more precise measurement.† This statement was to quickly become fiction with the beginnings of the 1900s. Two major problems in physics were still apparent; Theories on the luminiferous ether. ThatRead MoreEvaluating Kuhn ´s Theory of Scientific Development Essay1545 Words   |  7 Pagesof science. One of such is the Kuhn theory of science development postulated by Thomas Kuhn. His theory brought about a new perspective where scientific theories are placed in an umbrella of a grand theory called the paradigm. Thomas Kuhn who was born in 1922 in Cincinnati, studied physics at Harvard, graduating summa cum laude in 1943, applied his knowledge of quantum physics to humanities of science developing the Kuhn theory of science development (Bird, 2012). Although, earlier perspective ofRead MoreRelationship Between Mind And The Brain1270 Words   |  6 Pagesdualism. The dualist and physicalist have a long-standing feud regarding the mind and body. Before we can properly debate the mind-body problem, we must properly define what is physical. In this essay, I will argue that we cannot define what is physical. I will demonstrate this by anal yzing Barbara Montero’s essay called the Body Problem. I will explain the â€Å"body problem† , the problem(s) that arise from Hempal’s dilemma, and finally conclude that we should be more concerned if the mind is non-mentalRead MoreThe Progression Of Truths Within A Taxonomy1280 Words   |  6 PagesAn Essay on the Progression of Truths in a Taxonomy To begin understanding whether or not science progresses towards greater truths, truth must first be defined. It is the quality or state of conforming to fact or reality.1 As such a greater truth is one which better conforms to reality. Through scientific revolutions science progresses towards a taxonomy of greater truths. To accept this one must first understand that truths exist in science, that there are greater truths which replace falsifiedRead MoreThe Value Of Knowledge Is Greatly Diminished1566 Words   |  7 PagesAnezka Boyle O’Neill IB Theory of Knowledge Period 4 11-7-15 TOK Essay: â€Å"Without application in the world, the value of knowledge is greatly diminished.† Consider this claim with respect to two areas of knowledge. Knowledge can be defined as being skills or information acquired through experiences or encounters, an awareness of familiarity gained from an experience, and a theoretical or practical understanding of a subject. The last of these definitions is more of an arguable definition.

For example, the business man must come up with an idea to cut costs and increase revenue for his company. He must find a creative twist to an old idea, a new combination of numbers that allows the company to increase profit and drop costs. Yet this man strays from the numbers and thinks in images, and during the brief moment before the creative act his consciousness seems to play absolutely no role.

Great discoveries were made in the realm of science and technology which lead to the atomic age. One of the leading pioneers in the area of physics was Enrico Fermi. Without his contributions, the atomic bomb may not have been developed or would have possibly been postponed. Enrico Fermi was born into a family who had enough money to live comfortably. Fermi was born in Rome on the 29th ofRead MoreThe Rise Of Natural Science1425 Words   |  6 Pagesreligion-based societies tended to come to an end and there occurred two revolutions particularly in Western Europe: the French Revolution and the Industrial Revolution. Owing to them, society had been radically changed in terms of politics and economy albeit new other problems had been brought such as job competition and capital-based societies, in other word, capitalism (Hossain and Mustari, 2012: 64; Gollin, 1970: 1). As a result, in spite of the end of the absolute monarchy, there still remained the inequality
