![]() ![]() Another is that space-time possesses additional “supersymmetric” dimensions that would imply the existence of an entirely new mirror-world of particles that cancel out the troublesome quantum corrections from standard ones. One is that the Higgs boson is made of more basic entities held together by very strong forces, which circumvents the impact of quantum corrections. Apart from putting it beyond the reach of any conceivable experiment, such a heavyweight Higgs would not allow the universe as we know it to have formed.Īware of this paradox (called the electroweak hierarchy problem) long before the Higgs boson was discovered, and guided by the possible existence of particles and forces beyond those described by the Standard Model, physicists have come up with various explanations. Totting up these so-called quantum corrections would suggest a value for the Higgs-boson mass that is many orders of magnitude larger than is observed. But if this picture is true, the Higgs boson itself should gain mass from the interactions of known particles with its parent field. This field is understood to have come into existence during an epochal “electroweak” phase transition a fraction of a nanosecond after the Big Bang whereas, previously, elementary particles such as the electron had moved at the speed of light, they were forever after forced to interact with this quantum molasses, which imbued them with the property of mass. As with all elementary particles, it is an excitation, or quantum, of a more fundamental entity called a field – the uniquely featureless Brout–Englert–Higgs field, which fills all space uniformly. The Higgs boson is the simplest known particle: a “ fragment of vacuum” with no charge or spin. But where does the Higgs boson come from? And why is it so light that the LHC is able to produce it in droves? Such conundrums were discussed during a week-long workshop, Exotic Approaches to Naturalness, hosted by the CERN Theoretical Physics department from 30 January to 3 February. Precise measurements by the ATLAS and CMS collaborations show that this fundamental particle, which is responsible for generating the masses of elementary particles, behaves as predicted by the half-century-old Standard Model of particle physics. Hence we are continuously doing some amount of work in our daily life.The discovery of the Higgs boson at the Large Hadron Collider (LHC) in 2012 was a triumph of theoretical and experimental physics, yet its implications are only just beginning to be understood. We are playing badminton, energy is being transferred to the racket, we did work. We are piling up some packages on top of each other, work is being done. We are cleaning the floor by moving the mop forward and backward, we are doing work. ![]() The phenomenon of work in physics is the same as in the English language. If you are having any problem while calculating work or you still don’t understand how to calculate work done? then don’t worry! This online physics work calculator is used to calculate work done by an object on the other when force and distance are known. ![]() Work (W) = 250 Joules What is the work calculator?
