Collider sensitivity to SMEFT heavy-quark operators at one-loop in top-quark processes
Celine Degrande, Rogerio Rosenfeld, Andres Vasquez
We study the effects of four-heavy-quark operators in the production of top quarks in the framework of the Standard Model Effective Field Theory (SMEFT) at the LHC. In particular,…
A Note on the Quality of Dilatonic Ultralight Dark Matter
Jay Hubisz, Shaked Ironi, Gilad Perez +1
Dilatons are pseudo-Nambu-Goldstone bosons arising from the breaking of conformal invariance. In this letter we point out that in general a dilaton mass has a power-law dependence…
Physics Beyond the Standard Model
R. Rosenfeld
In these three lectures I review the need to go beyond the Standard Glashow- Weinberg-Salam Model and discuss some of the approaches that are explored in this direction.
Estimating sigma-meson couplings from D \to 3πdecays
C. Dib, R. Rosenfeld
Using recent experimental evidence from E791 on the sigma meson in D \to 3πdecays, we study the relevant couplings in D \to σπand σ\to π pi within the accepted theoretical framewor…
Can be sensitive to new physics beyond the Standard Model ?
R. Rosenfeld, L. A. Barreiro, C. O. Escobar +1
We investigate the impact of new physics beyond the Standard Model to the process, which is responsible for the short-distance contribution to the radiative dec…
A QCD Sum Rule Approach to the Contribution to the Radiative Decay
M. Nielsen, L. A. Barreiro, C. O. Escobar +1
QCD sum rules are used to calculate the contribution of short-distance single-quark transition , to the amplitudes of the hyperon radiative decay, $Ω^-\rightarrow…
