A kinematical basis for power form factors
S G Kamath M Gupta S Chakrabarty A N Mitra
A kinematical basis is proposed for form factors of the power type associated with multiple derivative couplings, on the basis of a Lorentz contraction effect on the external momenta involved in the transition matrix elements for mesons and baryons as appropriate quark composites. The argument (due to Licht and Pagnamenta) which applies separately to the Breit and c.m. frames for a decay matrix element provides a formal theoretical justification for the

The superconformal anomaly in the 1 + 1 dimensional Wess-Zumino model
The superconformal trace anomaly is worked out to one-loop order in perturbation theory for the 1+1 dimensional Wess-Zumino model.

When
How does the inclusion of a gravitational potential alter an otherwise exact quantum mechanical result? This question motivates this report, with the answer determined from an edited version
of a problem with a pair of masses sandwiched between three springs obeying Hooke’s law. To elaborate, we begin with the Hamiltonian associated with the vibration of the two masses
about their equilibrium positions in one dimension; the Schrödinger equation for the reduced mass is then solved to obtain the parabolic cylinder functions
