After the correct comments, this question is not here to compare gravity's and EM's long range forces' energetics and amplitudes to microscopic scattering amplitudes of such forces as weak and strong. I am basically trying to figure out if there is any observable effect in everyday life of the weak force. From the answers it is obvious that the weak force can be attractive or repulsive too. I am just trying to figure out if there is an observable effect of this (for the weak force) that we can see somehow in everyday life. Maybe not obvious, maybe we see it, experience it every day, we just do not know (that it is because of the weak force) it until it is explained in detail (like the strong force).
Maybe my question can be asked as simply as, 1. can the weak force pull/push (attr/rep) particles? 2. does it push/pull (attr/repl) particles in everyday life observable or is it just a rare thing, like decay? Does it hold something (particles) together or keep something apart in the everyday matter that we live in/around?
I have read these questions:
As it is currently known,
EM force is mediated by virtual photons, and can either be attractive or repulsive, and in everyday life it is easily observable, just hold a magnet. You can see the same thing with electricity. Then there is the covalent bond that makes molecules out of atoms. It is observable too, that the EM force is stronger on the short distance then gravity
gravity, just let something go, and you see it is always attractive, there are obviously observable effects in everyday life, and it is observable that gravity on the short distance is weaker then the EM force or the strong force
even the strong force, that keeps quarks confined, inside a nucleon, a neutron or proton, and the residual strong force that keeps neutrons and protons inside a nucleus, has an observable effect in everyday life, since without it, nuclei would not exist, they would fall apart. It is attractive on certain distances (between 0.8 fm and 2.5 fm), but it becomes repulsive at short distances (less then 0.7 fm), and that makes sure neutrons and protons do not get too close. This effect, though not commonly known, is responsible in part for giving material volume. It is observable too, that the strong force is stronger then gravity and EM on the short scale.
But what about the weak force? I know it can be repulsive or attractive, see here:
For weak isospin, there are two isospin charges (or flavors), up and down, and their associated anti-charges, anti-up and anti-down.
up repels up (anti-up repels anti-up)
down repels down (anti-down repels anti-down)
up attracts down (anti-up attracts anti-down)
up attracts anti-up (down attracts anti-down)
up repels anti-down (down repels anti-up)
For weak hypercharge, there is just one type of charge and its associated anti-charge.
hypercharge repels hypercharge (anti-hypercharge repels anti-hypercharge)
hypercharge attracts anti-hypercharge
Note that electric charge is a certain mixture of weak isospin and weak hypercharge.
OK, so I know that the weak force can be either attractive or repulsive. But the answers say too, that the weak or strong force does not have a classical field theory. Still, the strong force does have observable (in everyday life) attractive or repulsive effects.
- But what about the weak force, are there any effects that are in everyday life observable where the weak force is attractive or repulsive?
