LIGHT THERMAL RELICS ENABLED BY A SECOND HIGGS

Light thermal relics enabled by a second Higgs

Sub-GeV thermal relic dark matter typically Latches requires the existence of a light mediator particle.We introduce the light two-Higgs-doublet portal, illustrated by a minimal UV-complete model for sub-GeV dark matter with kinematically forbidden annihilations into leptons.All new physics states in this scenario lie at or below the electroweak sc

The effect of environmental factors on distribution of three oak species (Q. brantii Lindl., Q. libani Oliv. and Q. infectoria Oliv.) in northern Zagros forests

This study was carried out to explore the relationship between environmental factors and presence of three important oak species (Q.brantii, Q.libani, Q.infectoria) in northern Zagros forests.Following the site selection, vertical distributions were determined based on the minimum and maximum ranges species presence.A number of 54 circular Winch Bu
