The isopin breaking effect due to different masses and electric charges between up/down quarks are stuided non-perturbatively using lattice QCD+QED. Up, down, and strange quark masses are determined using K±,K0, and π± meson masses as inputs. The charge splitting of Kaon mass, mK± −mK0 , is broken up into the part coming from up, down quark mass difference and that from electromagnetic effects....

We consider low-dimensional dynamical systems exposed to a heat bath and to additional ac fields. The presence of these ac fields may lead to a breaking of certain spatial or temporal symmetries, which in turn cause nonzero averages of relevant observables. Nonlinear (non)adiabatic response is employed to explain the effect. We consider a case of a particle in a periodic potential as an example...

Physics of the low-lying and high-lying hadrons in the light flavors sector is reviewed. While the low-lying hadrons are strongly affected by both U(1) A and spontaneous SU(2) L × SU(2) R breakings, in the high-lying hadrons these symmetries are restored. A manifestation is a persistence of the chiral multiplet structure in both baryon and meson spectra. A fundamental origin of this phenomenon ...

New limits on couplings λjk , which break both the baryon number and the R–parity, are derived by using a new mechanism that contributes to the neutronanti-neutron oscillation. The constraints due to proton decay and its potential phenomenology are also reexamined. The minimal supersymmetric standard model (MSSM) [1] has been widely considered as a leading candidate for new physics beyond Stand...

Gauge coupling unification in the Supersymmetric Standard Models strongly implies Grand Unified Theories (GUTs). With grand desert hypothesis, we show that supersymmetric GUTs can be probed at future proton-proton (pp) colliders and Hyper-Kamiokande experiment. For with GUT scale MGUT≤1.0×1016 GeV, probe dimension-six proton decay via heavy gauge boson exchange Moreover, for MGUT≥1.0×1016 study...

We discuss magnetic moments of the baryons allowing for avour symmetry breaking in the quark magnetic moments. We nd that such a symmetry breaking is necessary to achieve consistency with data for the nucleon spin structure obtained from deep inelastic scattering. For the e ective magnetic moments we nd u= d = 1:79 0:06 and s= d = 0:68 0:05. We also calculate weak decay form factors, which in o...

Having in view the statistical data calculated for 10 years, the total consumption of rolling mill rolls represents 0 785...0 8 kg/tone of rolled steel. Nationwide, the 5 million tones steel being rolled every year represents a consumption of 4000 tones rolls, worth 6 million euro/year, which imposes large research with an important economic and scientific impact [1-6] It is noticeable that app...

The linear sigma model at finite baryonic density with a massive vector field is investigated considering that all the bosonic fields develop non zero expected classical values, eventually associated with condensates and corresponding to dynamical symmetry breakings which might occur in the QCD phase diagram. A modified equation for the classical vector field is proposed with its respective sol...

Downslope windstorms (DWs) are responsible for wildfires, wind gusts, and turbulence on the lee side of Taebaek Mountains in Yeongdong (YD) region Korea. We classified synoptic conditions YD using a self-organizing map (SOM). For windstorm events from 1979 to 2019, sea level pressure anomalies were used train SOM. It was found that patterns could be into three representative types: (1) south-hi...
