Tetraquarks at large M and large N

Journal of High Energy Physics
We study tetraquarks in large N QCD with heavy quarks, in the domain where non-relativistic quantum mechanics offers an adequate approximation. Within the regime of validity of the Born-Oppenheimer approximation, we systematically study and explicitly ...

A general model for analysis of linear and hyperbolic enzyme inhibition mechanisms

FEBS Open Bio, EarlyView.
We developed a general enzyme kinetic model that integrates these six basic inhibition mechanism onto a single one. From this model, we deduced a general enzyme kinetic equation that through modulation of simple parameters, γ (the relative inhibitor affinity for two binding sites) and β (the reactivity of the enzyme–substrate–inhibitor complex), is ...

Multi-spin soft bootstrap and scalar-vector Galileon

Journal of High Energy Physics, 2021
We use the amplitude soft bootstrap method to explore the space of effective field theories (EFT) of massless vectors and scalars. It is known that demanding vanishing soft limits fixes uniquely a special class of EFTs: non-linear sigma model, scalar ...

Molecular determinants of signal transduction in tropomyosin receptor kinases

FEBS Open Bio, EarlyView.
Tropomyosin receptor kinases control critical neuronal functions, but how do the same receptors produce diverse cellular responses? This review explores the structural mechanisms behind Trk signaling diversity, focusing on allosteric modulation and ligand bias.

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications

FEBS Open Bio, EarlyView.
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.

Two-loop amplitudes for processes gg → Hg, qg → Hq and qq¯→Hg $$ \mathrm{q}\overline{\mathrm{q}}\to \mathrm{H}\mathrm{g} $$ at large Higgs transverse momentum

Journal of High Energy Physics, 2018
We compute the two-loop QCD corrections to amplitudes for processes gg → Hg, qg → Hq and qq¯→Hg $$ q\overline{q}\to Hg $$ in the limit when the Higgs transverse momentum is larger than the top quark mass, p ⊥ ≫ m t .

Goldstone bosons on celestial sphere and conformal soft theorems

Journal of High Energy Physics, 2023
In this paper, we study celestial amplitudes of Goldstone bosons and conformal soft theorems. Motivated by the success of soft bootstrap in momentum space and the important role of the soft limit behavior of tree-level amplitudes, our goal is to extend ...

Enhancing Oncological Care for India's Aging Population: Addressing the Complex Needs of Older Adults With Cancer

Aging and Cancer, EarlyView.
Aging‐associated physiological and molecular alterations pose significant challenges in cancer management among India's elderly. Limited geriatric oncology expertise, financial constraints, and inadequate specialized care exacerbate disparities. Strategic expansion of insurance coverage, integration of palliative care, and infrastructural advancements ...

Power corrections to the production of a color-singlet final state in hadron collisions in the N-jettiness slicing scheme at NLO QCD

Journal of High Energy Physics
We compute next-to-leading power corrections in the zero-jettiness variable for the production of colorless final states at hadron colliders at next-to-leading order in QCD.

Mixed QCD⊗QED corrections to on-shell Z boson production at the LHC

Journal of High Energy Physics, 2020
We compute the mixed QCD⊗QED corrections to the production of on-shell Z bosons at the LHC at a fully-exclusive level. We also include the factorised NLO QCD correction to Z boson production and NLO QED correction to Z boson decay into two leptons.
