Search for photonic signatures of gauge-mediated supersymmetry in 8TeV pp collisions with the ATLAS detector
2015
A search is presented for photonic signatures motivated by generalized models of gauge-mediated supersymmetry breaking. This search makes use of 20.3 fb[superscript −1] of proton-proton collision data at √s = 8 TeV recorded by the ATLAS detector at the LHC, and explores models dominated by both strong and electroweak production of supersymmetric partner states. Four experimental signatures incorporating an isolated photon and significant missing transverse momentum are explored. These signatures include events with an additional photon, lepton, b-quark jet, or jet activity not associated with any specific underlying quark flavor. No significant excess of events is observed above the Stand…
Synthesis and Structures of Aluminum and Magnesium Complexes of Tetraimidophosphates and Trisamidothiophosphates: EPR and DFT Investigations of the P…
2005
Reactions of (RNH)3PNSiMe3 (3a, R = tBu; 3b, R = Cy) with trimethylaluminum result in the formation of {Me2Al(μ-NtBu)(μ-NSiMe3)P(NHtBu)2]} (4) and the dimeric trisimidometaphosphate {Me2Al[(μ-NCy)(μ-NSiMe3)P(μ-NCy)2P(μ-NCy)(μ-NSiMe3)]AlMe2} (5a), respectively. The reaction of SP(NHtBu)3 (2a) with 1 or 2 equiv of AlMe3 yields {Me2Al[(μ-S)(μ-NtBu)P(NHtBu)2]} (7) and {Me2Al[(μ-S)(μ-NtBu)P(μ-NHtBu)(μ-NtBu)]AlMe2} (8), respectively. Metalation of 4 with nBuLi produces the heterobimetallic species {Me2Al[(μ-NtBu)(μ-NSiMe3)P(μ-NHtBu)(μ-NtBu)]Li(THF)2} (9a) and {[Me2Al][Li]2[P(NtBu)3(NSiMe3)]} (10) sequentially; in THF solutions, solvation of 10 yields an ion pair containing a spirocyclic tetraimid…
Maaseudun paikka tulevaisuuden kestävässä yhteiskunnassa
2022
Fossiilitalous on yli satavuotisen historiansa aikana vapauttanut ihmiskunnan paikallisten luonnonvarojen kantokyvyn rajoista, mahdollistanut ennennäkemättömän talouden ja hyvinvoinnin kasvun. Samalla kiihdyttänyt keskittymiskehitystä ja kaupungistumista ja synnyttänyt ilmastonmuutoksen. Irtaantuminen fossiilitaloudesta merkitsee valtavaa yhteiskunnallista murrosta, joka jäsentää uudelleen ruoka-, energia- ja yhdyskuntajärjestelmiä. Tässä Maaseudun paikka tulevaisuuden kestävässä yhteiskunnassa -hankkeessa (MAKE) halusimme tarkastella maaseudun roolia tässä suuressa murroksessa. Hankkeessa tuotetut visiot, kestävän yhteiskunnan ilmentymät ja kestävyysmurroksen kipupisteet voivat toimia kesk…
La preservación del favor filii en supuestos de ruptura de la convivencia de los acogedores, tutores o guardadores del menor
2021
Cuando la guarda del menor por parte de los progenitores no es posible y esta es atribuida de forma conjunta a dos personas convivientes que posteriormente cesan dicha convivencia, resulta necesario determinar cuál de ellas va a ejercer a partir de ese momento las funciones inherentes a dicha guarda. Las posibles soluciones dependerán de si se trata de un supuesto de acogimiento, de tutela o de siempre guarda. When care of the child by the parents is not possible and is attributed jointly to two people living together who subsequently stop living together, it is necessary to determine which of them will exercise the functions inherent to the care from that moment on. The possible solutions …

Two-particle transverse momentum correlations in pp and p-Pb collisions at energies available at the CERN Large Hadron Collider
2023
Two-particle transverse momentum differential correlators, recently measured in Pb--Pb collisions at energies available at the CERN Large Hadron Collider (LHC), provide an additional tool to gain insights into particle production mechanisms and infer transport properties, such as the ratio of shear viscosity to entropy density, of the medium created in Pb-Pb collisions. The longitudinal long-range correlations and the large azimuthal anisotropy measured at low transverse momenta in small collision systems, namely pp and p-Pb, at LHC energies resemble manifestations of collective behaviour. This suggests that locally equilibrated matter may be produced in these small collision systems, simil…
Strictly correlated electrons approach to excitation energies of dissociating molecules
2019
In this work we consider a numerically solvable model of a two-electron diatomic molecule to study a recently proposed approximation based on the density functional theory of so-called strictly correlated electrons (SCE). We map out the full two-particle wave function for a wide range of bond distances and interaction strengths and obtain analytic results for the two-particle states and eigenenergies in various limits of strong and weak interactions, and in the limit of large bond distance. We then study the so-called Hartree-exchange-correlation (Hxc) kernel of time-dependent density functional theory which is a key ingredient in calculating excitation energies. We study an approximation b…

Constant sign and nodal solutions for parametric anisotropic $(p, 2)$-equations
2021
We consider an anisotropic ▫$(p, 2)$▫-equation, with a parametric and superlinear reaction term.Weshow that for all small values of the parameter the problem has at least five nontrivial smooth solutions, four with constant sign and the fifth nodal (sign-changing). The proofs use tools from critical point theory, truncation and comparison techniques, and critical groups. Spletna objava: 9. 9. 2021. Abstract. Bibliografija: str. 1076.
