The powerful machine LHC accelerates and steers billions of protons to collide with billions of
other protons. The goal of this work is to answer fundamental questions to understand Nature of the
proton and for each collision, the physicist’s want to count, track and characterize all the different
particles that were produced in order to reconstruct the process in full and they study the main parts
that are produced from this collision.
In this paper, we present a study of particle production in proton-proton collisions. Furthermore,
we present a new structure for proton similar to a cherry or to the sun with two layers; the Core and
the mantle. The core is almost spherical and fortified and its radius is about one-third of the entire
protons radius, but its density is about 15 times more than the mantle and the mantle is a brawny
layer, which includes about 2/3 of the total radius, and completely encircles the core by a much
lower density than it. When two protons collide the mantle part splits into two large fragments and
some tiny particles but the smash is not enough to split the dense core. So the heavy dense particle
which is called down quark is not anything other than the proton's core, the two parts of the mantle
that are larger, lighter and less dense than core, are not something other than the up quarks, and the
other small parts are photons and rays.
By this definition: 1. We no longer need to define the strong nuclear force 2. The existence of a
structure like this in the nature
