In particle physics, mesons (/ˈmiːzɒnz/ or /ˈmɛzɒnz/) are hadronic subatomic particles composed of one quark and one antiquark, bound together by the strong interaction. Because mesons are composed of sub-particles, they have a physical size, with a diameter of roughly one fermi, which is about 2⁄3 the size of a proton or neutron. All mesons are unstable, with the longest-lived lasting for only a few hundredths of a microsecond. Charged mesons decay (sometimes through intermediate particles) to form electrons and neutrinos. Uncharged mesons may decay to photons.
Mesons are not produced by radioactive decay, but appear in nature only as short-lived products of very high-energy interactions in matter, between particles made of quarks. In cosmic ray interactions, for example, such particles are ordinary protons and neutrons. Mesons are also frequently produced artificially in high-energy particle accelerators that collide protons, anti-protons, or other particles.
In nature, the importance of lighter mesons is that they are the associated quantum-field particles that transmit the nuclear force, in the same way that photons are the particles that transmit the electromagnetic force. The higher energy (more massive) mesons were created momentarily in the Big Bang, but are not thought to play a role in nature today. However, such particles are regularly created in experiments, in order to understand the nature of the heavier types of quark that compose the heavier mesons.
Los Miserables is a Chilean punk rock band formed in the early 1990s shortly after the demise of the military regime of Augusto Pinochet. The band is known for its songs charged with strong left-wing political ideas and anti-establishment commentary. The band has clearly presented itself as activist in its work with major participation in political events, international charity concerts, human rights events, and volunteer work in impoverished Chilean communities. The band has modeled itself in some ways after the famed Chilean band Los Prisioneros, who left a void after their initial break-up in 1990. Their albums can be found in Chile, Latin America, and the United States.
The band achieved major success in Chile in the mid-1990s, and is well known in Argentina, Colombia, and Mexico. They have recorded 8 albums, including three live albums, and received gold records in Chile. The band has also contributed songs to major Chilean movie soundtracks including the main song for the Chilean film El Leyton, a film by famed director Gonzalo Justiniano, of the films B-Happy (2003), Amnesia (1994), and Caluga o Menta (1990). They have also performed in tribute albums to Victor Jara, Violeta Parra, and Los Prisioneros.

We're well on our way in exploring how the strong force glues the nucleus together. The next phase of that research involves the production and study of hybrid mesons. David Lawrence explains how hybrid mesons are different from the regular variety.

The CMS and LHCb experiments at CERN have seen an important rare decay predicted by the Standard Model of particle physics. For every billion B_s mesons (pronounced B-sub-s) produced, only about three are expected to decay into two muons, heavier cousins of the electron. These decays are ideal processes in which to search for signs of new physics: a deviation from the precise predictions of the Standard Model (SM) would indicate the presence of physics “beyond the Standard Model” (BSM physics).

Este es un reportaje realizado por el periodista Saul Sanchez Lemus para el programa de Los Reporteros de Televisa.
I've got your calling card and it says don't call at
all.
All in all I've got no one and nobody gots me.
And due to excessive shoe loss,
yeah, they're falling off, they're falling off.
Without further adieu, I'm-a stop it all with signs and
everything and all.
If you didn't want to be here you shouldn't have come
at all.
WE'RE GONNA HAVE A BALL.
And if you don't come it's your loss.
Shake it from side to side.
This is Mexico and from here on out it's a no holds
barred.
See he's already in.
I've lost all momentum to attempt to have half of a
conversation with you.
But this is nothing new.
But this is nothing.
You're the worst thing that's happened to me and if I
was lying maybe we could agree to disagree.
"We're not working out"...
"I know, I know, I know, I know, I know, I know, I
know..."
Abrupt pause. "I know." ,
"I'll walk you out"... I'm on my way right now. We've
got to find that horse.
Well, let's go, where's your seatbelt? Let's grow, mi
dos.
Grow up? I've neglected to mention there's a hole in my
boat, we're not going anywhere.
You're still on mute, I'm a mime.
They call me Luke, It's short for Leukemia.
You keep getting louder.
I'm not accusing you, I'm just saying It's all your
fault.
You put the 'cool' in alcohol, and I've lost all
momentum to try to speak to you.
Alas, my fingers hurt from snapping, so, you better
stay on beat.
I'm lost and you know exactly where to find me, on and
on ...so wrong.
Silly girl, tricks are for kids, where's your tricks
now?
