Plane wave backgrounds and colour-kinematics duality

open access: yesJournal of High Energy Physics, 2019
We consider perturbative gauge theory on a fixed Yang-Mills plane wave background, describing its Feynman rules in detail. Using these rules, the tree-level 4-point gluon amplitude is computed.

Semileptonic B Decays into Excited Charmed Mesons ($D_1$, $D^*_2$) in HQEFT [PDF]

open access: yes, 2000
Exclusive semileptonic B decays into excited charmed mesons ($D_1$, $D^*_2$) are studied up to the order of $1/m_Q$ in the framework of the heavy quark effective field theory (HQEFT), which contains the contributions of both particles and antiparticles ...

Exclusive decay of $1^{- -}$ heavy quarkonium into photon and two pions [PDF]

open access: yes, 2001
We study the exclusive decay of $1^{--}$ heavy quarkonium into one photon and two pions in the kinematic region, where the two-pion system has a invariant mass which is much smaller than the mass of heavy quarkonium.

An Analytical Approach for the Two-Dimensional Plunging Breaking Wave Impact on a Vertical Wall with Air Entrapment

open access: yesFluids, 2020
This study investigates an idealized formulation of the two-dimensional impact of a breaking wave on a vertical impermeable wall. An overturning-like wave is assumed, which is close to the concept of a plunging breaker.

Evaluation of average travel delay caused by moving bottlenecks on highways. [PDF]

open access: yesPLoS ONE, 2017
This paper presents a modelling framework to evaluate travel delay of all vehicles influenced by moving bottlenecks on highways. During the derivation of analytical formulas, the arrival of slow vehicles was approximated by a Poisson process based on the

On duality of color and kinematics in (A)dS momentum space

open access: yesJournal of High Energy Physics, 2021
We explore color-kinematic duality for tree-level AdS/CFT correlators in momentum space. We start by studying the bi-adjoint scalar in AdS at tree-level as an illustrative example.

Chiral effective theory predictions for deuteron form factor ratios at low Q^2 [PDF]

open access: yes, 2006
We use chiral effective theory to predict the deuteron form factor ratio G_C/G_Q as well as ratios of deuteron to nucleon form factors. These ratios are calculated to next-to-next-to-leading order.

Resonance Enhancement by Suitably Chosen Frequency Detuning

open access: yesMathematics, 2020
The theory of exact resonances (kinematics and dynamics) is well developed while even the very concept of detuned resonance is ambiguous and only studies of their kinematic characteristics (that is, those not depending on time) are available in the ...

Study of Underwater and Wave Gliders on the Basis of Simplified Mathematical Models

open access: yesApplied Sciences, 2022
Both underwater and wave gliders are known as autonomous unmanned energy-saving vehicles which have recently found applications for monitoring the world ocean.
