Baryon octet electromagnetic form factors in a confining NJL model

open access: yesPhysics Letters B, 2016
Electromagnetic form factors of the baryon octet are studied using a Nambu–Jona-Lasinio model which utilizes the proper-time regularization scheme to simulate aspects of colour confinement.

P-Wave Charmonium Production in B-Meson Decays

open access: yes, 1992
We calculate the decay rates of $B$ mesons into P-wave charmonium states using new factorization formulas that are valid to leading order in the relative velocity of the charmed quark and antiquark and to all orders in the running coupling constant of ...

SU(3) analysis of weak decays of doubly-heavy tetraquarks $${b\bar{c}}{q\bar{q}}$$ bc¯qq¯

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
We study the weak decays of exotic tetraquark states $${b\bar{c}}{q\bar{q}}$$ bc¯qq¯ with two heavy quarks. Under the SU(3) symmetry for light quarks, these tetraquarks can be classified into an octet plus a singlet: $$3\bigotimes \bar{3}=1\bigoplus 8 ...

Probing compositeness with the CMS eejj & eej data

open access: yesPhysics Letters B, 2016
Quark-lepton compositeness is a well-known beyond the Standard Model (SM) scenario with heavy exotic particles like leptoquarks (LQs) and leptogluons (LGs) etc. These particles can couple to leptons and jets simultaneously.
