I am facing problem to write the matrix Us
Can anybody help me to write the complete matrix?
I am planning to publish a paper after extending my MS thesis work. What i am planning to to do is not something new. Some people worked on those recently i will extend that for more models using their formalism. But to do that lots of numerical and computational work is needed. I have written...
i think the part of z (ϵμ∗ )boson is correct but there is a problem in vertex. Because sterile neutrino does not interact in weak interaction so it will not couple to z boson. so you need to do something different here. You can check Mahapotro's " Massive neutrinos in physics and astrophysics "...
Thanks Ben . But will you please explain that why the sign of d3 does not change. Is it because of spherical co-ordinates : d3p = p2sin(theta)d(theta)d(phi)dp , where p = |p| ?

Cost free physics journals for authors??
if i m not wrong Journals like Physics review a,b,c,d charge from authors to publish papers. But is there good journals which don't charge from authors? What about Journal of High energy physics and European physics journal? Do they also charge? :rolleyes:
