The molecular states in coupled channel system of $B_s^0N-\bar B\Lambda-\bar B^*\Lambda-\bar B\Sigma-\bar B^*\Sigma$ are investigated within one-boson-exchange model that includes $S$-$D$ wave mixing and a tunable short-range $\delta(r)$…
We investigate non-minimal Higgs inflation in a no-scale-inspired supergravity framework and confront its predictions with the latest CMB constraints from ACT DR6 and \emph{Planck}. Working within a shifted hybrid inflation scenario, we…
We study exclusive electroproduction of dijets in the collinear factorization framework as a probe of generalized parton distributions (GPDs). For quark dijet production, we extend previous analyses by including contributions from helicity…
In the present study, we extend our previous analysis of the proton electromagnetic form factors (FFs) extracted from exclusive photon leptoproduction (EP) measurements in kinematic regions where the Bethe-Heitler (BH) process dominates the…
Neutrino oscillations provide compelling evidence for physics beyond the Standard Model, while the weakly interacting nature of neutrinos makes them powerful probes of new interactions and hidden sectors. In this work, we investigate a…
Arroyo-Ure\~na, Hern\'andez-Tom\'e, L\'opez-Castro, Roig, and Rosell (AHLRR) take the structure-dependent (SD) amplitude for $\tau \to P \nu_\tau \gamma$ from the resonance chiral theory result of Guo and Roig (GR10), obtaining $\delta…
We calculate the magnetic dipole moments of doubly strange hidden-charm pentaquark states with spin-parity $J^P = 1/2^-$ and $3/2^-$ using QCD light-cone sum rules (LCSR), presenting the first systematic LCSR investigation of the…
We present a comprehensive analysis of the $\pi^+p$ femtoscopic correlation functions measured by the ALICE Collaboration in high-multiplicity $pp$ collisions at $\sqrt{s}=13$ TeV. Using the Koonin-Pratt formula with a Gaussian source and…
We compare the size of dimension-8 effects on $W^+W^-$ production at the LHC arising from the $q\bar q$ and $\gamma\gamma$ initial states. In particular, we consider bosonic operators, which contribute to the anomalous triple and quadruple…
We update the analysis of minimal supersymmetric SO(10) grand unification with a universal, constrained-MSSM-like soft-breaking spectrum. A pair of Yukawa matrices in the ${\bf 10} \oplus \overline{\bf 126}$ Higgs sector fixes the charged…
We investigate the spectroscopic properties of the double strange hybrid baryon with quark content $ssqg$ within the framework of QCD sum rule. Using an interpolating current with explicit gluonic degrees of freedom, the two-point…
The cross-section for photoproduction of a vector meson on a nucleus is usually determined in nucleus-nucleus collisions, which introduces a two-fold ambiguity as to which nucleus emitted the photon. This can be resolved in asymmetric…
Using the quantum field theory, we derive a Breit-Wigner-type formula for the $e^+ e^-$ annihilation into a vector meson and its antiparticle, and relate the formula parameters to observable quantities. The formula's soundness is checked by…
Quasi-PDFs provide a connection between Euclidean spatial correlations in lattice QCD and lightcone parton distributions. Their perturbative expressions contain both the infrared divergence required for matching and the scheme-dependent…
The axion, a hypothetical particle proposed to solve the strong CP problem and considered a viable candidate for dark matter, has prompted extensive experimental efforts for its detection. This study presents a novel approach combining…
PQ solution to the strong CP problem probably encounters the axion domain wall problem. In this article, we propose a simple and testable solution, assuming that the $U(1)_{\rm PQ}$ possesses mixed anomaly to a hidden $SU(N_c)$ color. Then,…
Standard routes to a light composite Higgs either rely on tuning a single channel near criticality or protect a pseudo-Nambu--Goldstone coordinate of a coset. We introduce a third mechanism class in which the protected object is an…
Two-sided octonionic $E_6^L\times E_6^R$ unification carries a nominal second colour $SU(3)_{c'}$ which, gauged, would colour the charged lepton and must be suppressed by hand. We argue no such device is needed: the left-right symmetry acts…
We show that with the introduction of new right-handed neutrinos $N_R$, the Peccei--Quinn ($PQ$) transformation in the DFSZ (Dine--Fischler--Srednicki--Zhitnitsky) model depends only on the $PQ$ charge of the scalar singlet $\phi$, namely…
We present a relativistic study of the exclusive double-charmonium processes $e^-e^+ \to \gamma^*\gamma^* \to \chi_{c1}+\eta_c$ and $e^-e^+ \to \gamma^*\gamma^* \to h_c+h_c$ at $\sqrt{s}=10.6$ GeV in the framework of the $4\times4$…
