Heavy Pentaquarks in the Diquark Model and the Large N_c Expansion
Margaret E Wessling
Recent experimental evidence for the Theta^+(1540) has given rise to much theoretical interest in exotic baryons. The Theta^+ is a baryon that has strangeness S=+1, meaning that it…
Negative-Parity Heavy Pentaquark States in 1/N_c
Margaret E. Wessling
The 1/N_c expansion for negative-parity heavy pentaquarks is developed using the formalism introduced for excited baryons in large N_c. Relations are found between the mass splitti…
Stable Heavy Pentaquark States
Iain W. Stewart, Margaret E. Wessling, Mark B. Wise
If the Theta^+(1540) is interpreted as a bound state of a quark and two (ud) diquarks in a relative P-wave, then it is very likely that there exist pentaquark states with…
The Long Range Gravitational Potential Energy Between Strings
Margaret E. Wessling, Mark B. Wise
We calculate the gravitational potential energy between infinitely long parallel strings with tensions τ_1 and τ_2. Classically, it vanishes, but at one loop, we find that the long…
