Vector meson spectral function in a dynamical AdS/QCD model
European Physical Journal C: Particles and Fields, 2022 By using gauge/gravity duality, we calculate the spectral function of the heavy vector mesons with the presence of an intense magnetic field in a hot and dense medium.

Systematic Approach to Gauge-Invariant Relations between Lepton Flavor Violating Processes
, 2004 We analyze four-lepton contact interactions that lead to lepton flavor violating processes, with violation of individual family lepton number but total lepton number conserved.

Lepton-Quark Collisions at the Large Hadron Collider.
Physical Review Letters, 2020 Processes commonly studied at the Large Hadron Collider (LHC) are induced by quarks and gluons inside the protons of the LHC beams. In this Letter, we demonstrate that, since protons also contain leptons, it is possible to target lepton-induced processes

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

The decomposition of neutron-antineutron oscillation operators
Journal of High Energy Physics, 2023 We study the systematic decomposition of the dimension nine neutron-antineutron oscillation operators at tree and one-loop levels. We discuss the topologies’ generation and the assignment of the chiral quarks.

Preserving the Lepton Asymmetry in the Brane World [PDF]
, 2002 In models where the Standard Model spectrum is localized on a brane embedded in a higher dimensional spacetime, we discuss the lepton number violation induced by the emission of right-handed neutrinos from the brane.

Leptonic scalars at the LHC [PDF]
Journal of High Energy Physics, 2020 Abstract We explore the collider prospects of neutrino non-standard interaction with a Standard Model (SM) gauge-singlet leptonic scalar ϕ carrying two units of lepton-number-charge. These leptonic scalars are forbidden from interacting with the SM fermions at the renormalizable level and, if one allows for higher-dimensional ...

Hunting for ALPs with lepton flavor violation [PDF]
Journal of High Energy Physics, 2019 We examine the low-energy signatures of axion-like particles (ALPs) in lep- ton flavor violating (LFV) processes. By using a dimension-5 effective Lagrangian, we compute the most general ALP contributions to LFV decays of leptons and mesons. The provided

Nonconventional Techniques in Plant Alkaloid Extraction: A Decade of Progress (2014–2023)
Chemistry &Biodiversity, EarlyView.This figure seeks to represent the evolution of the different unconventional approaches that were adopted for the extraction of plant‐derived alkaloids during the decade from 2014 to 2023. ABSTRACT Plant metabolism encompasses primary and secondary pathways, with secondary metabolism yielding diverse natural products crucial for plant adaptation and ...
