Last summer, physicists announced that they had identified a particle with characteristics of the elusive Higgs boson, the so-called "God particle." But, as often the case in science, they needed to do more research to be more certain.
On Thursday, scientists announced that the particle, detected at the Large Hadron Collider, the world's most powerful particle-smasher, looks even more like the Higgs boson.The news came at the Moriond Conference in La Thuile, Italy, from scientists at the Large Hadron Collider's ATLAS and Compact Muon Solenoid experiments. These two detectors are looking for unusual particles that slip into existence when subatomic particles crash into one another at high energies.Scientists have analyzed two and a half times more data than they had when the first announced the Higgs boson results last July 4.
The Higgs boson is associated with the reason that everything in the universe -- from humans to planets to galaxies -- have mass. The particle is a component of something called the Higgs field, which permeates our universe. The electron would have no mass if it not experience the effect of Higgs field the same is the case with humans also. So, without the Higgs boson, we would not be here at all says scientists.

| Inside LHC |
Large Hadron Collider(LHC) :
The Large Hadron Collider is located in a 17-mile tunnel near the French-Swiss border, and is operated by CERN, the European Organization of Nuclear Research.The $10 billion particle-smasher set a record in 2012 for the amount of energy achieved in particle collisions: 8 trillion electron volts (TeV). The LHC shut down last month for a long staycation full of maintenance and upgrades. After about two years, it will come back online with 13 TeV.Detecting the Higgs boson takes a lot of particle collisions -- there's only one observed event in every trillion proton-proton collisions, So according to scientists it takes still more time to arrive at a concrete opinion regarding the existence of Higgs Boson.
how do the scientists estimate the size of the particles?

Hi Harish I searched the answer for your question with every possible way what i came to know is that there were no instruments capable of measuring the size of the subatomic particles and that is why even today we dont have exact details regarding the size of the particles. The estimation is done through formulating equations by using basic laws (newton's law,couloumb's law, mass energy equivalence)that involve radius of the particle and the other known properties like charge,mass and constants like speed of light and planck's constant etc.,.An equation will be developed by various assumptions such that the unknown quantity(radius)will be as a function of known quantities and constants..This is how a rough estimate of size will be done.
ReplyDeleteBy searching the web I came across this link which made an attempt to measure the size of electron which include very complex physics
http://www.alternativephysics.org/book/ElectronStructure.htm
also an approximate method to find size of electron can be found here using classical electron radius method http://scienceworld.wolfram.com/physics/ElectronRadius.html
What i feel is in the case of other particles also same procedure is followed as in electron.
Awaiting discussion on this...
thank you
Did i know how to block some restricted sites in my computer ?

Hi akhil:
ReplyDeleteIts quite easy to block restricted sites in your computer..Just follow these steps..(Windows7 And i think the same with others also)
1) Login as an administrator.
2) Search for "internet options" in search box in start menu..
3) Internet options dialog will pop up and click "privacy" tab there.
4) Then in the privacy select "Sites". Here you can provide the address of restricted site and hit "Block".. Voilaa !! You had blocked a site in your computer..
In case of blocking in a particular browser, browser privacy setting must be changed...
