Most of the research going on these days is about the higgs boson and its technological benefits. The higgs boson is a massive elementary particle that was predicted to exist by standard particle physics and discovered by experiments carried out in the large hadron collider. A boson is a force...
a result of 47 has a deviation of three from the average (or “mean”) value of 50. The standard deviation is just the square root of the average of all the squared deviations. One standard deviation, or one sigma, plotted above or below the average value on that normal distribution...
$CP$ Properties of Higgs Boson Interactions with Top Quarks in the $t\\bar{t}H$ and $tH$ Processes Using $H ightarrow \\gamma\\gamma$ with the ATLAS Detector A study of the $CP$ properties of the interaction between the Higgs boson and top quarks is presented. Higgs bosons are ident...
orabsolutelyweak. It’s not about whether the force could break a window, or hold up a bar of gold. “Strong” and “weak” in this context aresemi-absoluteterms, in a sense that we never use in daily life, or even in undergraduate physics classes. It’s a...
What is the significance of potential in electromagnetic field? What is the Higgs boson and why is it important? What is an example of a physical entity that is quantized? State specifically what the entity is and what the limits are on its values. What is the difference between quantum mec...
Fig. 1: At left, the mass-type neutrinos (neutrino-1, -2 and -3) have definite masses (still unknown, though some differences of the squares of their masses are known throguh the measurements described below.) At right: the weak-type neutrinos (the electron-, muon- and tau...
In this channel, we do not find the dilution of significance of the 'SM-like' Higgs boson that is naively expected because of the mixing. This is because of leakage of events from the other scalar into its signal region. Nevertheless, we show that the broadening of theh→WW→lνlν...
As an example, we show that a light Higgs boson produced in weak-boson fusion with a subsequent decay into muons can be extracted from the backgrounds. The method, aimed at phenomenological studies, can be incorporated in parton-level event generators and accommodate parametric descriptions of ...
Higgs bosonKM quark-mixing matrixCP violationThis chapter presents tests of significance concerned with comparing properties of different populations. It discusses whether the means of two populations are equal, whether the variances of two populations are equal, and whether the variances of more than ...
