Particle Physics as a Building Block of the Universe
نویسنده
چکیده
The Standard Model in particle physics describes the forces, components and reactions of the basic particles that make up matter. Also it predicts that there is an elementary particle, the Higgs boson, which would produce the effect of mass. In this paper we have first focused some important milestones of physical laws extending to standard model. We have then considered some particulars of Higgs boson showing the associated dominant features and the properties involved therein. It further highlights how the Higgs boson has become a key missing piece for astronomers and physicists to understand the basic building blocks of the universe. The effects of fundamental forces are described in natural world including four kinds of symmetry associated with microworld. The progresses in the field of cosmic microwave background as well as the role of gravitational wave and cosmic shear have been critically examined with a view to interfacing particle physics and cosmology together. Different techniques employed for solar radio observations and the instruments used for the successful recording of radio emissions from the Sun are summarized pointing out the early attempts for the same. The expansion of the wavelengths for astronomical observations in recent years is critically examined and the different sources of radio waves are noted besides measured and unwanted signals at any radio observatory. The importance of the role of detectors as well as receiver with radio telescope antenna have considered besides aperture synthesis, an approach to high angular resolution with radio telescope. The possibilities of different type of polarizations in astronomical radio sources have been focused and information for any investigation on radio astronomical universe is discussed. The roles of neutrino astronomy and gravitational wave astronomy have also been highlighted. The recent experiment using Large Hadron Collider and its planning for further development is highly promising in astroparticle research. As the temperature fell below a critical value with the expansion of the early universe, an invisible force field called the 'Higgs field' came into play throughout the cosmos in addition to 'Higgs boson'. We have also highlighted the major epochs and the related main events linked to the formation of the universe and which in turn is associated with the Higgs boson particle. The correct explanation for the expansion of the Universe is still unknown but a possible source of interpretation will come through the ideas of 'dark matter' and 'dark energy'. The background and sources of …

Noether Symmetry in f(T) Theory at the anisotropic universe
As it is well known, symmetry plays a crucial role in the theoretical physics. On other hand, the Noether symmetry is a useful procedure to select models motivated at a fundamental level, and to discover the exact solution to the given lagrangian. In this work, Noether symmetry in f(T) theory on a spatially homogeneous and anisotropic Bianchi type I universe is considered. We discuss the Lagran...

متن کاملA Scientific Comment of the Quranic Expression of bi Ghayri Amadin Tarownaha about Raising up, Raf,`and Creating, Khalq, the Heavens
Some contemporary commentators have taken the Quranic expression of bi Ghayri Amadin Tarownaha, the verses 2 of Ra`ad and 10 of Loqman, as referring to gravity and its role in the creation of the high building of Heaven. It is as if the gravitation has been taken as some invisible columns; since taking gravitation as column is not a scientifically sound analogy, this article, while critiquing a...
متن کاملMessenger Particles and Relativity
This article is an attempt to expose the role played by messenger particles in physics. The concept of the ”messenger particle” has long been considered in physics. The latest research shows evidence that the four fundamental forces of nature ,Gravitation, Electromagnetic and the Weak and Strong Nuclear forces are all created by messenger particles. This hypotheses is leading to a new way of th...
