Pentaquarks, Elusive or Non-existent?
Outline:
Beginning in 2003, scientists claim to have experimental evidence of a five-quark combination, and it is now being called a pentaquark. Pentaquarks are postulated subatomic particles consisting of four quarks and one antiquart. Scientists that have done research believe it to exist; others are doubtful skeptics that are against its existence.

Pentaquarks, Elusive or Non-existent? First of all, what is a pentaquark? A pentaquark is a postulated subatomic particle consisting of four quarks and one antiquart. Whether or not this particle is real has yet to become determined, making the pentaquark currently theoretical. Scientists that have done research in the past believe it to exist; others are doubtful skeptics of the modern world that are against its existence. There are positive and negative evidences confirming and denying its existence. This heated debate has everyone asking the question: Who has the correct prediction?

There are a lot of people involved in the origin of the pentaquark. This controversy has raged since the first pentaquark sighting was confirmed by more than ten other labs. "In 2003, there were lots of positive results, everybody found something," says Battaglieri. A review of data taken in 1997/98 at the ELSA accelerator in Strong evidence for the pentaquark came from experiments at the Jefferson Lab in Newport News, Virginia during 2003. A retrospective study of 1986 bubble chamber
