Complete meson-meson scattering within one loop in Chiral Perturbation Theory: Unitarization and resonances [PDF]

, 2001
We review our recent one-loop calculation of all the two meson scattering amplitudes within SU(3) Chiral Perturbation Theory, i.e. with pions, kaons and etas.

The Ds0(2590)+ as the dressed cs¯(21S0) meson in a coupled-channels calculation

Physics Letters B, 2022
The recent discovery of the Ds0(2590)+ meson by the LHCb Collaboration has stimulated the analysis of meson-meson channels effects in the two-body quark-antiquark meson spectrum.

One park, two owners—Inconsistencies in forest stewardship

Conservation Science and Practice, Volume 4, Issue 12, December 2022., 2022
Data and experiences from the Šumava NP are used to elucidate varied management approaches applied by state and private municipal owners in forests of high conservation value. We used high resolution aerial photographs to evaluate the effects of forest management practices applied, and compared the status of spruce habitats before and after a major ...

The role of meson exchanges in light-by-light scattering

Physics Letters B, 2017
We discuss the role of meson exchange mechanisms in γγ→γγ scattering. Several pseudoscalar (π0, η, η′(958), ηc(1S), ηc(2S)), scalar (f0(500), f0(980), a0(980), f0(1370), χc0(1P)) and tensor (f2(1270), a2(1320), f2′(1525), f2(1565), a2(1700)) mesons are ...

$\delta$ meson effects on neutron stars in the modified quark-meson coupling model

, 2008
The properties of neutron stars are investigated by including $\delta$ meson field in the Lagrangian density of modified quark-meson coupling model. The $\Sigma^-$ population with $\delta$ meson is larger than that without $\delta$ meson at the beginning,

Composite leptoquarks and anomalies in B-meson decays [PDF]

, 2014
A bstractWe attempt to explain recent anomalies in semileptonic B decays at LHCb via a composite Higgs model, in which both the Higgs and an SU(2)L-triplet leptoquark arise as pseudo-Goldstone bosons of the strong dynamics.

Measurement of branching fractions for D meson decaying into ϕ meson and a pseudoscalar meson

Physics Letters B, 2019
The four decay modes $D^{0}\to ^{0}$, $D^{0}\to $, $D^{+}\to ^{+}$, and $D^{+}\to K^{+}$ are studied by using a data sample taken at the centre-of-mass energy $\sqrt{s} = 3.773$~GeV~with the BESIII detector, corresponding to an integrated luminosity of 2.93 fb$^{-1}$. The branching fractions of the first three decay modes are measured to be ${

The non-perturbative unquenched quark model

EPJ Web of Conferences, 2017
In recent years states in the quarkonium spectrum not expected in the naive quark model have appeared and created a lot of interest. In the theoretical side the study of the effect of meson-meson thresholds in the spectrum have been performed in ...

Free energies as invariants of Teichmüller like structures [PDF]

, 2013
A Teichmüller like structure on the space of d-degree holomorphic maps on the circle S1, marked by conjugations to the map z 7→ z d, can be defined. Here we introduce a definition of free energy associated to this kind of dynamics as an invariant of ...
