Nucleon-antinucleon Interaction from the Modified Skyrme Model
We calculate the static nucleon-antinucleon interaction potential from the
modified Skyrme model with additional term using the product
ansatz. The static properties of single baryon are improved in the modified
Skyrme model. State mixing is taken into account by perturbation theory, which
substantially increases the strength of the central attraction. We obtain a
long and mid range potential which is in qualitative agreement with some
phenomenological potentials.Comment: 21 pages, 7 figur
Lepton flavor violating and conversion in unparticle physics
We have studied lepton flavor violation processes and
conversion in nuclei induced by unparticle. Both and conversion rate strongly
depend on the scale dimension and the unparticle coupling
(K=V, A, S, P). Present experimental upper bounds on
, and put stringent constraints on the parameters of unaprticle physics. The
scale dimensions around 2 are favored for the unparticle scale
of and the unparticle coupling of
. is proportional to
for the pure vector and scalar couplings between
unparticle and SM fermions, this peculiar atomatic number dependence can be
used to distinguish unparticle from other theoretical models.Comment: 16 pages, 5 figure
