Potential analysis of holographic Schwinger effect in the magnetized background

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
We study the holographic Schwinger effect with magnetic field at RHIC and LHC energies by using the AdS/CFT correspondence. We consider both weak and strong magnetic field cases with $$B\ll T^2$$ B≪T2 and $$B\gg T^2$$ B≫T2 solutions respectively. Firstly,

Deciphering the Belle II data on B → Kν ν ¯ $$ B\to K\nu \overline{\nu} $$ decay in the (dark) SMEFT with minimal flavour violation

open access: yesJournal of High Energy Physics
Recently, the Belle II collaboration announced the first measurement of the branching ratio B B + → K + ν ν ¯ $$ \mathcal{B}\left({B}^{+}\to {K}^{+}\nu \overline{\nu}\right) $$ , which is found to be about 2.7σ higher than the Standard Model (SM ...

$${b\rightarrow c\tau \nu }$$ b→cτν transitions in the standard model effective field theory

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
The $$R(D^{(*)})$$ R(D(∗)) anomalies observed in $$B\rightarrow D^{(*)}\tau \nu $$ B→D(∗)τν decays have attracted much attention in recent years. In this paper, we study the $$B\rightarrow D^{(*)}\tau \nu $$ B→D(∗)τν , $$\Lambda _b\rightarrow \Lambda _c ...

Charged-Lepton Flavour Physics

open access: yes, 2012
This writeup of a talk at the 2011 Lepton-Photon symposium in Mumbai, India, summarises recent results in the charged-lepton flavour sector. I review searches for charged-lepton flavour violation, lepton electric dipole moments and flavour-conserving CP ...

Phenomenological anatomy of top-quark FCNCs induced by a light scalar singlet

open access: yesJournal of High Energy Physics
Scalar singlets under the Standard Model gauge group appear naturally in many well-motivated New Physics scenarios, such as the composite Higgs models. Unlike the Higgs boson in the Standard Model, they can induce large flavour-changing neutral currents (

Unraveling the final-state interactions and correlations inside high-multiplicity jets at LHC [PDF]

open access: yesEPJ Web of Conferences
Recent CMS measurements on high-multiplicity jets have revealed intriguing near-side long-range correlations in two-particle correlations within jets containing over 80 charged tracks.

Parametrized leptogenesis from linear seesaw

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
We present a purely linear seesaw mechanism in a mirror left-right symmetric framework and then realize a novel leptogenesis scenario for parametrizing the cosmic baryon asymmetry by the charged lepton masses, the light Majorana neutrino mass matrix and ...

Predicting the flavour and SUSY flavour structure from grand unified theories [PDF]

open access: yes, 2016
Grand Unified Theories (GUTs) offer an attractive framework for flavour models, since they feature relations between quarks and leptons. Combining them with Supersymmetry (SUSY) and flavour symmetries, we derive predictions for the flavour and SUSY ...

Lepton flavor violation and local lepton number

open access: yesPhysical Review D
We investigate the predictions for lepton number violating processes within the minimal theory of neutrino masses based on the spontaneous breaking of local lepton number. In this framework, the symmetry is broken at the low scale, leading to the existence of a viable dark matter candidate.

Lepton flavor violation as a probe of quark-lepton unification [PDF]

open access: yesPhysical Review D, 2005
The recent measurements of the solar neutrino mixing angle theta_{sol} and the Cabibbo mixing angle theta_C reveal a surprising relation, theta_{sol}+theta_C ~ pi/4. Interpreting this empirical relation as a support of the quark-lepton unification, we find that the PMNS mixing matrix can be decomposed into a CKM-like matrix and maximal mixing matrices,
