Model independent bounds on the modulus of the pion form factor on the unitarity cut below the threshold
B. Ananthanarayan, I. Caprini, Diganta Das +1
We calculate upper and lower bounds on the modulus of the pion electro magnetic form factor on the unitarity cut below the inelastic threshold, using as input the phase in the…
Consistency tests of AMPCALCULATOR and chiral amplitudes in SU(3) Chiral Perturbation Theory: A tutorial based approach
B. Ananthanarayan, Diganta Das, I. Sentitemsu Imsong
Ampcalculator is a Mathematica based program that was made publicly available some time ago by Unterdorfer and Ecker. It enables the user to compute several processes at one-loop (…
New Physics Effects and Hadronic Form Factor Uncertainties in B -> K^* l^+ l^-
Diganta Das, Rahul Sinha
It is well known that New Physics can contribute to weak decays of heavy mesons via virtual processes during its decays. The discovery of New Physics, using such decays is made dif…
Isolating New Physics Effects from Hadronic Form Factor Uncertainties in B\to K^* \ell^+\ell^-
Diganta Das, Rahul Sinha
The discovery of New Physics, using weak decays of mesons is difficult due to intractable strong interaction effects needed to describe it. We show how the multitude of "related ob…
Tadpole cancellation in top-quark condensation
Diganta Das, Kosuke Odagiri
We show that quadratic divergences in top-quark condensation are cancelled when the tadpoles cancel. This latter cancellation is naturally implemented as the cancellation among the…
