Recent results from Beyond Standard Model(BSM) at LHC

, 2014
I present the results for searches beyond the Standard Model (BSM) at the LHC by the ATLAS and CMS collaborations. The minimal supersymmetric extension of the SM has been investigated in various configurations and lower limits are set on the s-particle ...

Barr-Zee diagrams at a high-energy muon collider

Journal of High Energy Physics
The sensitivity of electron EDM experiments has been increasing at a rapid pace, and could yield indications of new physics in the coming decade. An intriguing possibility is that an EDM signal could be generated by new, electroweak-charged particles at ...

Meson mixing bounds on Z ′ mass in the alignment limit: establishing the phenomenological viability of the 331 model

Journal of High Energy Physics
We perform a systematic study of flavor-changing neutral currents (FCNCs) in the 331 model with right-handed neutrinos (331RHNs), analyzing constraints on the Z ′ boson mass from K-, D-, B d -, and B s -meson oscillations.

Searches for BSM physics in ATLAS

, 2016
The Standard Model (SM) doesn't provide all answers to what is observed in nature. Some open questions remain, such as gravity, Dark Matter/Energy and Hierarchy problem, which are explain by the SM.

Powerful Yukawas

Journal of High Energy Physics
We introduce a class of models where the masses of the light Standard Model fermions are due to an Effective Field Theory operator that appears beyond dimension-4 in the power counting expansion, resulting in a ‘Powerful Yukawa’.

MadbaM: automated tools for precision calculations of the Baryon Asymmetry of the Universe in BSM models

, 2019
The measured Baryon Asymmetry of the Universe (BAU) is a firm evidence for the existence of new physics beyond the Standard Model of particle physics (BSM). Despite of that, the offer of scientific software for the high-energy physics community currently

Entrepreneurial Innovation and Sustained Long-run Growth without Weak or Strong Scale Effects [PDF]

R&D-based growth theory suggests that a larger population size raises either the long-run rate of economic growth (“strong scale effect”) or the level of per capita income (“weak scale effect”), with far-reaching policy implications.

Positivity from J-Basis operators in the standard model effective Field Theory

Journal of High Energy Physics
In the effective field theory (EFT), the positivity bound on dim-8 effective operators tells us that the s 2 contribution in the scattering amplitude of 2-to-2 process geometrically corresponds to the convex cone composed of the ultraviolet (UV) states ...
