No, it is not.  That is the *collision* energy coming from at least *two* 
colliding protons.  You want to read page 3 and following of the 2009 
edition of the LHC Guide:

<http://cds.cern.ch/record/1165534/files/CERN-Brochure-2009-003-Eng.pdf#page-3>

> Via E = mc2 the mass is simply 7 TeV/c2 -

["mc2" and "c2" are not proper notations.  If you cannot use Unicode -- 
"mc²" and "c²", respectively -- you have to find an ASCII-compatible way to 
express powers.  The usual way is to use the circumflex/caret character, so 
it would be "mc^2" and "c^2", respectively.]

As has been explained here many times before (including several times by 
me), E = m c² (E = m c^2) is only true for the energy at relative rest,
E = E(v = 0) = E(p = 0) =: E₀.

The full equation for energy, and thereby the mass–energy equivalence, that 
can be derived from the norm of the four-momentum is

  E = √((m c²)² + (p c)²)                                               (1)

 [E = sqrt((m c^2)^2 + (p c)^2)],

with momentum

  p = γ m v                                                             (2)

 [p = gamma m v],

and the Lorentz factor

  γ = 1∕√(1 – (v∕c)²)                                                   (3)

 [gamma = 1/sqrt(1 - (v/c)^2)],

therefore, applying (3) to (2),

  p = m v∕√(1 – (v∕c)²)                                                 (4)

 [p = m v/sqrt(1 - (v/c)^2)],

and finally, applying (4) to (1),

  E = m c³ √(1/(c² − v²))

 [E = m c^3 sqrt(1/(c^2 - v^2))],

assuming m > 0, c > 0, and v ≥ 0 (v >= 0).

As you can read in the LHC Guide, the protons in the LHC, when they reach 
their greatest relative velocity, move with 99.9999991 % of the speed of 
light in vacuum, or 0.999999991 c.  So it is very important not to ignore 
the part of their energy that comes from their relative motion.  In fact, 
that is why we need particle *accelerators* for achieving high particle 
energies, therefore the chance for producing heavy particles like the 
discovered Higgs boson, in the first place.

Well, would be quite impossible to collide a proton alone. What is the
cross-section of a proton?

Most of the time this is talked about as a "differential" cross section, 
where this means essentially the rate of scattering where the incoming 
particle is scattered by a particular angle.

This is a classical mechanics problem, and Rutherford worked it out when 
he was trying to figure out alpha-nucleus scattering.

https://en.wikipedia.org/wiki/Rutherford_scattering

The equation is the one directly *above* the section header "Details of 
calculating maximal nuclear size". For proton-proton scattering, Z=1.

Congratulations, you actually managed to top the stupidity of the question 
of the ’nym-shifting troll with a wrong answer that has nothing to do with 
it.

You just said collision of *two* protons, and dare to call the others 
stupid and wrong?

PointEears:
"No, it is not.  That is the *collision* energy coming from at least
*two* colliding protons."

Hey Pointy, let me ask you in this way. Can the collision of one proton be 
directed towards something other than another proton? You are great, keep 
up the good work.

Why should that question be stupid? You are not as much stupid PointHead 
is. Or you both know nothing about cross-section ☭ Very funny indeed ♫♪♫♫

The stupid must be you, pointhead. Cross-sections are IMAGINARY, pointhead, 
you don't need to cut. Say it to the other pointhead, so he can learn, 
cross-sections. ┌∩┐(◣_◢)┌∩┐

Thanks for the Clarification, That is what I was Figuring ... 
I consider Space time ( the totality of ) to be "Kinetic Energy" .... so that fits RIGHT IN .. Thanks for the pointer. 

Mass exists Precisely because of the Vacuum's Impedance to velocity. 

The Mass = (376.73 / c) Times the Kinetic energy of the Vacuum = (376.73  c)*c^2 or simply (376.73 * c) which is 1 / (376.73 * the speed of light) = 8.85419518 × 10^-12 s / m 
Or the Reciprocal of the vacuum permittivity 

So is This ...[((((4 * pi * (10^(-7)))^2) / 2)^pi = 9.5176229e-39 ] starting to Sink in YET ???

You know the meaning of mc2 and c2 so why are you knit picking Fuller on keyboard fonts and the " standard format " if you knew what his meaning was? This is off subject to the question at hand yes / no ?

Yeah, Sorry ..That was just Garbage ["mc2" and "c2"] I copied and pasted from the CERN Site. normally I correct it. Big Difference between 4pi and 4^pi

You want to reconsider.  Spacetime is a mathematical framework for 
describing reality instead.  E is the energy of an object in spacetime — 
which does not need to move relative to the observer; p can be 0 and the 
object still has energy —, not the energy of spacetime itself.  In fact,
the total energy of the universe is very likely 0.

The relativistic kinetic energy of a rigid body is instead

  E_k = m γ c² – m c².

Note how with γ = 1∕√(1 – (v∕c)²) the kinetic energy of a rigid body *also* 
depends on the frame of reference as v is the speed of the object relative 
to the stationary observer, and that it becomes zero if m γ c² = m c²; that 
happens precisely when γ = 1 which requires that v = 0 (no relative motion).

No, that is you just performing the "Hand Waving Maneuver"
Do it this way then

sqrt(The pi root of 10^-39 / 2) = vacuum permeability approx.

The vacuum impedes velocity

Fascinating.  But you probably did not know that years ago a reknowned Dutch 
astronomer, Cornelis de Jager, found out that many of the fundamental 
physical constants, and even astronomical measures, are actually provided by 
Dutch roadsters (a kind of city bicycle).

I could not find the original article [1] online, so I thought I should give 
you the privilege of learning about the most important parts of this amazing 
discovery and new school of thought, called Cyclosophy (in Dutch: 
Velosofie), from me, right here (taken from German translations that I have 
found):

If one defines the quantities, as carefully measured on the aforementioned 
vehicle,

  P – pedal travel
  W – front wheel diameter 
  L – lamp diameter
  B – bell diameter

then it turns out that

          P² √(L B) = 1823 ≈ m_p∕m_e (proton mass∕electron mass)

              W²∕P⁴ = 1∕137 ≈ α (fine structure constant)

  1∕P⁵ 3 ∛(L∕(W B)) = 6.67 × 10⁻⁸ ≈ G (gravitational constant in ft³∕slugs²)

            √P ∛B/L = 1.496 ≈ 1 au (in units of 10⁸ km)
 
and finally (if you are not sitting already, you better sit down before you

Vacuum is a medium that is devoid of matter that could hinder the motion of 
particles traveling through it (by them colliding).  It is therefore the 
best medium to enable motion, not to hinder it.  For that reason, for 
example the speed of light is greatest in a vacuum.

but that just works out to 

1/(c*50) = G  .. It is Not Exact 

1 / (the speed of light * 50) = 6.6712819 × 10^-11 s / m

The "WHY" is completely IGNORED

WHY = https://goo.gl/photos/xQvTEFVJPSHhwNEV7 

https://goo.gl/photos/1wLBgxBT8ySVAJoM6 


Think (Surface area m^2 of a Sphere - 1^2) ^2 ... 
1/(1^2) now = 1- (1 / 24.1327412287) = 0.95856252 

1 - 0.95856252 = 0.04143748 

137 + 1/((4pi)^2 - (4pi-1)^2) = 137.041437481 


pi / ((11 * 2) / 7) = 0.9995976625

I simplified THAT mess for you ......

Magnetic permeability = (4pi * 10^-7)

(4pi * 10^-7)/ ((11^2 + 4^2)*(11/4) = 3.33546665e-9 Hz

1/((4pi * 10^-7)/ ((11^2 + 4^2)*(11/4) )= 299808124.049

There is no mess to simplify, you poor lunatic.  It is nonsense intended to 
be that; actually, it is sarcasm about crazy people like you who arbitrarily 
put in numbers (like, “who cares about dimensions?”) and actually assign 
meaning to the inevitable outcome of these plays with numbers.
 
> Magnetic permeability = (4pi * 10^-7)

Do you even read what you are replying to?  B is _not_ meant to be the 
magnetic field here; it is the bell diameter, the diameter of a bicycle’s 
bell – bell as in ringing, not in Bell Labs.  So the magnetic permeability 
does not even feature here.

And I can’t believe that you are taking this seriously.  Get some 
professional help, will you, *please*?
