In 2015, researchers at the Large Hadron Collider found data suggesting the existence of super-rare, super-elusive particles called pentaquarks. Tara Shears explains how our investigation into these particles has the potential to revolutionise our lives in every aspect.

It's here – the last of our trilogy of Tara Shears films talking about discoveries at the LHC. And on the day we reached 700K subscribers no less. Coincidence? We think not.
Importantly, we're just in the middle of planning our content for 2020 so hands up if you'd like more stuff like this! (And maybe also tell us if it was the topic, or the format, or Tara, or something else that you liked, or if there's something else you are wondering about and we could quiz a scientist about.)
this houses the homeless and feeds the hungry HOW?
What we know about strong force? Where it comes from? How it occurs? Why it is there? And many more questions. I think we know very little about forces rather than particles.
Tara's communication tone and style really are spot on. The content was surprisingly accessible. More!
Dr. Shears got me hooked on this channel (good writing Anand!) and I am still waiting for her talk on why all the particles and antiparticles in the Universe didn't instantly annihilate 100%. It's been years since her talk. YEARS.
6-pack quark is coming up next
It's gonna be really exciting to find out !
Strong force, weak force, electromagnetic force, magnetic force,and gravity are not found inside of particles.These are field attributes.Fields are immaterial. The LHC will be a monument to forever remember the foolishness of Spending 100’s of millions of dollars searching for magical particles trying to rationalize materialism. I do hope I am wrong and they discover the magic fairy dust that transforms the world but I’m not holding my breath.
Excellent summary on the LHC signals indicating the existence of the tetraquark and the more recently discovered pentaquark.
Can you detect the strong force like we do the electromagnetic force? Can the strong force be observed above the quantum scale?
yes yes science…

If a pentaquark can be thought of as a baryon bound with a meson, then a deuteron can be thought of as a hexaquark, and deuterons are stable.
So when I am painting..I am really painting quarks with quarks no matter the colour
Wouldn't a Quark and an anti Quark annihilate each other when they came into contact inside a Meson?
I have a question concerning pentaquarks and potentially larger multi-quark barrions. We know that as a neutron star gains mass, so too does it's volume decrease. Is it possible that penta/multi quark barrion formation account for this loss of volume? Also, assuming that higher orders or multi-quark barrions exist in extreme environs such as neutron stars, wouldn't this also affect the effective neutron degeneracy pressure making these barrions capable of supporting far higher levels of pressure prior to collapse?
Not realistic comparing applications of the electron to applications which may arise from pentaquarks…. Electrons are stable AND plentiful. That kind of hype is just to justify the huge expense of the lhc… Just like there won't be useful applications of Higgs bosons.
What do pentaquarks do?
What are the possibilities of a subatomic 3d printer ?
They are so rare because they only occur that we know of at one place. Like Faberge eggs they are carefully crafted under very specific conditions by specialists in the field of exotic particle manufacture. And like Faberge eggs they are very expensive and essentially an entertainment for the ruling class who will tout them as miracles of human endeavor while people are dying from hunger and starvation. But hey, all the money spent on these devices and all the bloated salaries of all those researchers is nothing compared to the waste in the military.
Please! Seriously? Finding more combinations of quarks is going to lead to something like Faraday!?
0:25 I hear morse code
Is higg boson or God particle
Or higgs field is responsible for stick
U d d particle in neutron.
Because there is a strong field
Can it act as glue to stick Two or three quarks in Barrion and messon
This glue is a higgs field ?
MADAM
The color of quarks in neutron if
U DD
Is green blue red
Means D quarks (down)
Has found in two colors
And also in proton UUD
U had found in two colors
So every quarks can have two colors
Every quarks means k pi strange b t d u
And other quarks must represent in two colors
Please explain
If what is found universe is tetra quarks stable to form neutrons protons
But if
Other universe or galaxy possess pentaqurks and quadra quarks stable and form heavy matter than proton and neutrons
Then ….
I can want to oder food out of thin air. 😂
Lovely
