Charmonium production in pNe collisions at $$\sqrt{s_{\scriptscriptstyle \text {NN}}} =68.5$$ s NN = 68.5 GeV

European Physical Journal C: Particles and Fields, 2023
The measurement of charmonium states produced in proton-neon ( $$p\text {Ne}$$ p Ne ) collisions by the LHCb experiment in its fixed-target configuration is presented.

The ancient art of laying rope [PDF]

, 2010
We describe a geometrical property of helical structures and show how it accounts for the early art of ropemaking. Helices have a maximum number of rotations that can be added to them -- and it is shown that this is a geometrical feature, not a material ...

An optimal condition for the uniqueness of a periodic solution for linear functional differential systems

Electronic Journal of Qualitative Theory of Differential Equations, 2009
Unimprovable effective efficient conditions are established for the unique solvability of the periodic problem $$ \begin{aligned} u'_i (t)&=\sum\limits_{j=2}^{i+1} \ell_{i,j}(u_{j})(t) + q_i(t) \qquad \text{for} \quad 1 \leq i\leq n-1,\\ u'_n (t ...

Shedding light on the X(3930) and X(3960) states with the $$B^- \rightarrow K^- J/\psi \omega $$ B - → K - J / ψ ω reaction

European Physical Journal C: Particles and Fields, 2023
We have studied the contribution of the state X(3930), coming from the interaction of the $$D \overline{D}$$ D D ¯ and $$D^{+}_s D^{-}_s$$ D s + D s - channels, to the $$B^- \rightarrow K^- J/\psi \omega $$ B - → K - J / ψ ω decay.

Numerical prediction and experimental analysis of ends-together yarn splicing [PDF]

, 2016
Pneumatic yarn splicing is a technical process for joining two yarn ends together. The process involves injecting compressed air into a splicing chamber. The inlet pressure and chamber slope determine the main parameters affecting this process.

Pólya fields and Kuroda/Kubota unit formula

Mathematics Open, 2023
Let K be a number field. The Pólya field concept is used to know when the module of integer-valued polynomials over the ring of integers [Formula: see text] of K has a regular basis. In [C. W.-W.

Measurement of $$\tau _\text {L}$$ τ L using the $${B} _s^0 \rightarrow J/\psi \eta $$ B s 0 → J / ψ η decay mode

European Physical Journal C: Particles and Fields, 2023
Using a proton–proton collision data sample collected by the LHCb detector and corresponding to an integrated luminosity of $$5.7~\text {fb}^{-1}$$ 5.7 fb - 1 , the lifetime of the light $${{B} ^0_{s}} $$ B s 0 mass eigenstate, $$\tau _{L}$$ τ L , is ...
